Best Free Gutenberg Block Plugins and Tools: 35 Options

The best free Gutenberg block plugin depends on what you need to build. Kadence Blocks is a strong starting point for business pages with responsive layouts, GenerateBlocks suits custom designs assembled from flexible building blocks, and Ultimate Blocks focuses on the extras that make long articles easier to navigate.

This guide covers 35 plugins and tools, from complete block libraries to table editors, form builders, and theme-development utilities. They aren’t all substitutes for one another. A few need special attention: the supplied Spectra plugin is now Spectra Legacy, some older tools carry compatibility warnings, and ACF’s custom-block feature requires Pro.

Our recommendations use official plugin descriptions and documentation, checked on October 21, 2026. This is a research-based comparison, without hands-on speed or usability rankings.

Start with the job you need to do

• Build service pages or a small business site: Compare Kadence Blocks and Stackable. Kadence offers layout, text, gallery, and form blocks; Stackable puts particular emphasis on coordinated design settings. Both reserve additional features for paid versions.
• Create custom layouts and post listings: Start with GenerateBlocks. Its free plugin includes layout primitives, a Query block, and dynamic tags; additional query and data options require Pro.
• Improve long articles: Choose Ultimate Blocks for a table of contents, content toggles, tabs, and other publishing features. Coupon and Timeline blocks are paid additions.
• Fix one specific content problem: Flexible Table Block handles complex tables; Syntax-highlighting Code Block extends WordPress’s existing Code block. Neither requires adopting a whole page-building system.
• Show different blocks to different visitors: Compare Block Visibility with Conditional Blocks. Conditional Blocks explicitly limits its free edition to three built-in conditions plus a developer API.
• Build your own reusable blocks: Look at Lazy Blocks if you can write the output template. ACF Free does not include ACF Blocks.

For freemium products, “free” means the downloadable plugin has usable features without purchasing its paid edition. It doesn’t mean every advertised template, integration, AI service, or advanced block is included. Hosting and any external service costs are separate.

All-in-one Block Suites

These tools cover page construction and related features. Conditional Blocks serve a narrower purpose within this group: controlling when existing blocks appear.

Spectra

The supplied Spectra download is now named Spectra Legacy. It includes containers, headings, calls to action, post layouts, forms, and other blocks, but its current role is maintaining sites already built with that plugin.

Brainstorm Force says Legacy continues to receive security and compatibility updates and support, while new features go into a separate product called Spectra Blocks. Existing users do not face a required migration or deadline.

Choose it for: Continuing an existing Spectra site. For a new project, assess the separate current product before choosing this Legacy download. Features identified as Spectra Pro Legacy, including its Loop Builder, aren’t part of the free offer.

Kadence Blocks

Kadence Blocks combines structural blocks with practical page elements: Row Layout, Advanced Text, buttons, accordions, galleries, and Advanced Form. Device-specific typography controls help you adjust how headings and body text fit different screens.

That mix makes it a useful first candidate for a services homepage, landing page, or small business site. You can build the page structure and its supporting content within one block library.

Free scope: The core toolkit is free; Pro expands its capabilities. Check the specific feature you need rather than assuming a premium demo can be reproduced in the free plugin. For example, its listing distinguishes Pro evergreen countdown campaigns from the standard countdown.

Conditional Blocks

Conditional Blocks adds display rules to blocks you already use. Its free edition documents three built-in conditions: hide from everyone, show according to logged-in or logged-out status, and control visibility by screen size. Developers also get a Conditions API for custom rules.

A practical use is showing a sign-in prompt to logged-out visitors while displaying a different message to members. The lockdown condition can hide a section while you prepare it.

Free scope: Three built-in conditions and the API. Advanced conditions belong to Pro. Despite its placement among suites, this is a visibility utility, not a library of page layouts.

Gutenberg Essential Blocks

Gutenberg Essential Blocks offers a broad collection of content and design blocks, including accordions, image treatments, buttons, and social elements. Its copy-and-paste styling feature is useful when several blocks need the same treatment.

Consider it when a page needs several specialized elements that would otherwise require separate plugins. Before committing, identify the actual blocks you need and check them against the free collection.

Free scope: A free block library with paid enhancements. The listing also promotes AI text and image features, but a free plugin download doesn’t establish cost-free access to an external AI service. Choose it on its block features unless you’ve separately checked the AI requirements.

Otter Blocks

Otter Blocks combines additional blocks and patterns with tools that extend the editor. Its documented features include custom CSS and animation controls, which can be useful when the missing capability is styling an existing block.

This gives it a different appeal from a library chosen mainly for ready-made sections: you can consider Otter for both new page elements and adjustments to the blocks already on a page.

Free scope: A free core plugin with an Otter Pro upgrade. Its listing discusses the broader product family, so verify paid features before building around dynamic content or advanced commercial-site requirements.

Gutenverse

Gutenverse brings page-building controls, templates, global color and typography settings, and responsive controls into the native WordPress editing workflow. Its Site Editor support makes it relevant when the project extends beyond individual pages to headers, footers, and post templates.

Choose it for: A coordinated site design using a block theme and the Site Editor. Page-level blocks and site-wide template editing solve different tasks; confirm your theme supports the workflow you intend to use.

Free scope: Core blocks, template-library access, responsive controls, global styles, and layout tools. Pro adds capabilities including advanced forms, dynamic data, and display conditions. Check the selected template and any companion-product requirements separately.

Nexter Blocks

Nexter Blocks, available under the older “the-plus-addons-for-block-editor” plugin slug, provides a broad page-building toolkit. Its documented free collection includes a Flexbox Container and layout, typography, and content blocks.

The useful comparison is between the free blocks you would actually deploy and those in another suite. The total product count includes a larger paid offering.

Free scope: A free block collection, with Pro adding further blocks and capabilities. The listing specifically places AI credits, dynamic content, display conditions, and WooCommerce blocks among Pro features. Don’t budget a free store build around those paid additions.

Stackable

Stackable emphasizes a shared design system: global colors, typography, spacing, and other settings alongside content blocks and ready-made designs. That approach is useful for a site whose pages need to share a consistent visual language.

Compare it with Kadence when you need both page-building elements and reusable styling decisions. Stackable’s appeal is the coordination across those elements, rather than a particular block count.

Free scope: The core plugin is free. Premium adds dynamic content, conditional display, integrations such as ACF and WooCommerce, and additional motion and agency tools. Those capabilities should not be assumed from the free download.

Qubely

Qubely documents row and column layouts, predefined sections, responsive controls, tabs, accordions, testimonials, and post grids. It has the feature set of a general page-building toolkit.

Maintenance caveat: At the research date, WordPress.org warns that Qubely hasn’t been tested with the latest three major WordPress releases. Its listed last update is March 10, 2025.

The warning does not establish that every installation is broken. It does make Qubely a cautious choice for a new build: assess compatibility on staging before relying on it. It remains relevant to readers maintaining an existing Qubely site, but isn’t part of our starting shortlist.

Lightweight and Layout Builders

This group covers layout-oriented tools, but “lightweight” isn’t a measured ranking here. The plugins vary considerably in scope; a smaller block count alone doesn’t prove a faster site.

GenerateBlocks

GenerateBlocks takes a building-block approach with containers, grids, text, buttons, images, shapes, and queries. Instead of choosing a separate predesigned block for each section, you combine these elements into the layout you need.

The free plugin also documents a Query block and dynamic tags, making it relevant to custom post listings as well as static pages. It works with themes beyond GeneratePress.

Choose it for: Custom layouts where you want to control the structure. Pro expands querying and dynamic data options, including post-meta query parameters and additional tags. Its modular approach may require more assembly than a template-led suite.

Greenshift

Greenshift is a candidate for layouts that need more detailed control over positioning, CSS grid, flexbox, and motion. Its listing describes responsive controls, hover transitions, and animation capabilities alongside page-building blocks.

Choose it for: A design where interaction and movement are deliberate requirements, rather than extras added after the page is finished.

Free scope: A free core plugin with a broader add-on ecosystem. Check the extension required for a particular demo or advanced workflow. The developer makes performance claims, but this comparison does not establish Greenshift as faster than other tools on the same site.

CoBlocks

CoBlocks supplies rows and columns alongside content blocks such as galleries, services, pricing tables, forms, and food-and-drink listings. The latter gives it a concrete use case for restaurant and hospitality content.

Compatibility caveat: Its current WordPress.org page carries the warning that it hasn’t been tested with the latest three major WordPress releases. The listed last update is March 5, 2026.

Its free availability and relevant blocks don’t remove that compatibility question. If you’re maintaining a CoBlocks site, check the blocks it uses during upgrades; for a new project, compare currently verified alternatives before committing.

Getwid

Getwid combines section-building tools with content blocks such as image boxes, banners, sliders, icon boxes, and headings. The official description identifies its block collection and premade templates as free.

It is worth considering when you want a variety of familiar business-page elements without starting from a premium template package. A section might combine a banner, service descriptions, and an image-and-text presentation from the same library.

Choose it for: Business and editorial pages needing a broad free content toolkit. Check individual blocks for external-service requirements; an integration block and the service it connects to aren’t necessarily the same cost.

Genesis Blocks

Genesis Blocks includes containers, advanced columns, testimonials, pricing, post grids, and a Section & Layout block. The layout library is its main reason to enter a shortlist: it offers starting structures for pages and sections.

Free scope: Core blocks and the included layouts are available free; Genesis Pro adds a larger library and additional capabilities.

Existing-site note: The plugin documents conversion of its deprecated Button block to WordPress’s core Buttons block when you open affected content in the editor. Review the result if that content uses custom button styling.

Gutentor

Gutentor provides page-building blocks with controls for columns, backgrounds, spacing, borders, and other layout details. Its template workflow offers another way to begin a page without constructing every section from scratch.

Choose it for: Comparing a template-led building workflow with the more primitive-led approach of GenerateBlocks. Gutentor’s scope extends beyond a small collection of layout helpers, so assess it as a page-building system.

Free scope: The core plugin is free. Its description also references related products and template services; confirm what a chosen design requires before importing it into a project.

Blog and Content Blocks

Ultimate Blocks

Ultimate Blocks focuses on publishing features: a table of contents, content toggles, tabs, content filtering, review presentation, and calls to action. For an article-led site, these can answer a more immediate need than another container or row system.

Choose it for: Structuring long posts and giving readers ways to navigate or reveal supporting information. It is our first shortlist pick for that specific task.

Free scope: The listed core publishing blocks are free, while Coupon and Timeline are explicitly marked Pro. Schema-capable blocks provide markup tools; they don’t guarantee Google rich results or improved rankings.

PublishPress Blocks

PublishPress Blocks pairs extra content blocks with editorial management tools. Its documented features include control over which blocks user roles can use and a block-usage tool for finding blocks across a site.

That makes it particularly relevant to a multi-author publication. The decision isn’t only what an editor can design, but which controls the publishing team should expose to different contributors.

Free scope: A free edition with a Pro upgrade. Check the exact management or visibility feature you need against the edition documentation; the overall product description covers a wider set of capabilities than a simple block list.

Flexible Table Block

Flexible Table Block addresses tables directly. It supports merging and splitting cells, styling individual cells and captions, and selecting multiple cells for editing.

Responsive options include horizontal scrolling and arranging cells vertically on mobile, with configurable breakpoints. Those are useful choices for specification tables that need more structure than a simple two-column list.

Choose it for: Comparison charts, schedules, and other content where table editing is the actual problem. It is a free specialist plugin, so you can evaluate it without adopting a general page builder. Keep header labels clear when using complex merged cells.

Syntax-highlighting Code Block

Syntax-highlighting Code Block extends WordPress’s core Code block instead of introducing a separate publishing system. Highlighting happens on the server, so the plugin doesn’t need a front-end JavaScript highlighting library.

It documents automatic language detection, a manual language override, line numbers, highlighted lines, and optional wrapping. Existing core Code blocks can benefit from the extension.

Choose it for: Tutorials and technical articles that publish source code. The plugin is free. Its description notes that highlighting is applied to the rendered output rather than providing syntax highlighting inside the editor itself.

Qi Blocks for Gutenberg

Qi Blocks for Gutenberg is a broader design collection than this category name suggests. Its free base includes custom blocks with detailed presentation options, while Premium expands the collection.

Choose it for: Comparing content treatments and visual options for an editorial site, portfolio, or branded page. Look at the particular block’s demo and edition rather than selecting it on the overall collection size.

Free scope: A free base plugin. Qi Blocks Premium and the related Qi Templates offering are separate considerations; the free download doesn’t establish access to every design shown across those products.

The Icon Block

The Icon Block adds a dedicated way to insert SVG icons into the block editor. Its controls include icon sizing and colors, and it supports custom SVG input.

Choose it for: Service lists, supporting labels, and other places where a meaningful icon is the missing page element. It is a narrower choice than installing a large suite primarily to obtain an icon block.

Free scope: The plugin is free. Permission to use a custom icon still depends on that asset’s license; the ability to paste SVG does not grant rights to the artwork.

GutenBee

GutenBee offers content blocks including headings, icon boxes, image boxes, icon lists, and image comparisons. The image-comparison block gives it a specific role for pages showing edits or before-and-after work.

It can also supply supporting business-page content without making theme development the focus of the project.

Choose it for: A page needing several of those content treatments, particularly a visual comparison. The free plugin provides the block collection; check the blocks you intend to use with your theme before building a larger library of reusable sections around them.

Forms and Templates

Form plugins, template importers, and block suites solve different parts of page creation. Use this group to fill a missing workflow rather than treating every entry as a replacement for your layout plugin.

Fluent Forms

Fluent Forms builds forms through its own form builder and provides block-editor integration, including a Gutenberg Form Styler. The documented free edition includes conditional logic, entry exports, form scheduling, notifications, and spam-protection integrations.

Choose it for: Enquiry forms where the fields need to change according to earlier answers. Free conditional logic is a meaningful distinction when comparing it with WPForms Lite.

Free scope: A usable free form builder; Pro adds capabilities such as multi-step forms, file uploads, and additional integrations. Payment services and AI features require their own terms check if you plan to use them.

WPForms Lite

WPForms Lite is another dedicated form builder whose forms can be placed in block-editor content. It is a candidate for a basic contact or feedback form, rather than a source of layout blocks.

Its directory page describes both Lite and the broader paid product. Features appearing in the overall marketing copy aren’t automatically available in Lite.

Free scope: Basic form building in the Lite plugin. The listing identifies conditional logic, file uploads, and multi-page forms among paid capabilities. If your enquiry form depends on conditional questions, compare that requirement with Fluent Forms’ documented free logic before choosing.

Starter Templates

Starter Templates imports complete site designs, individual pages, and sections. It is useful when you want a visual starting point rather than a blank page and a collection of blocks.

Choose it for: Beginning a new site from a suitable template. Select a Gutenberg-compatible design: a template built for Elementor belongs to a different editing workflow. Current Gutenberg templates are described as powered by Spectra Blocks, so inspect the required plugins before importing.

Free scope: Free templates are available alongside paid options and AI-related services. A free importer doesn’t make every design or service in its library free.

GutenKit

GutenKit combines layout containers, content blocks, patterns, and templates with a page-builder-style workflow inside Gutenberg. It is relevant to readers who want to construct complete pages using ready-made pieces.

Choose it for: Evaluating template-assisted layouts and detailed page controls within the native editor. It is a broader toolkit than a template importer alone.

Free scope: A free plugin and a separate premium edition. Its headline description includes advanced features across the product family; check the edition of the exact block or module required by a demo before making it part of a free build.

BlockArt Blocks

BlockArt Blocks offers section, heading, paragraph, and other page blocks alongside prebuilt sections and templates. Its modular controls let you enable or disable individual block types.

That makes it worth comparing when you want a starting library but prefer to limit the blocks exposed in the editor to those the project uses.

Choose it for: Building business or nonprofit pages from sections and then adjusting their content and styling. The core plugin is free. Review the selected template’s requirements before importing, especially if it introduces elements beyond the blocks you planned to use.

ZoloBlocks

ZoloBlocks provides blocks, patterns, page templates, and responsive containers for the native editor. Its import and export options for patterns are relevant when reusing layouts across pages or projects.

Choose it for: Comparing reusable page patterns with a manually assembled layout workflow.

Free scope: A free edition with paid tiers. The listing explicitly describes the advertised collection as a mixture of free and Pro blocks. Features such as loops, effects, or menus need an individual edition check. Optional AI text generation also connects to a third-party service, which has separate requirements.

Editor enhancements and developer tools

Block Visibility

Block Visibility adds conditions to existing blocks. Its free plugin documents scheduling, logged-in and logged-out states, user roles, screen sizes, and query-string-based rules, alongside integrations for more specialized conditions.

Choose it for: Scheduled promotions, role-specific messages, or other conditional content without adding a second block library. It deserves comparison with Conditional Blocks when the latter’s three free built-in conditions don’t cover the task.

Free scope: The downloadable plugin includes the documented visibility controls. Integrations can require the corresponding plugin or service. Screen-size visibility should not be treated as a way to protect sensitive content.

Editor Plus

Editor Plus documents visual styling controls for typography, spacing, borders, backgrounds, animation, and custom CSS, plus blocks such as tabs and accordions.

Maintenance caveat: Its last listed update is November 9, 2023, and WordPress.org warns that it hasn’t been tested with the latest three major releases. We would not start a new project around it without resolving that compatibility concern.

It remains in this guide for readers who already use it or encounter it in an older site. Free availability is not enough to make it a current recommendation over maintained alternatives.

Lazy Blocks

Lazy Blocks is a custom-block builder. You configure a block, add controls for its content, and write the output using HTML or PHP. The plugin also documents import and export options for moving block definitions.

Choose it for: A reusable component with a defined editing interface, such as a staff profile or project summary, when you can implement the output template.

Free scope: The free plugin supports custom-block creation. It is a more relevant starting point than ACF Free when the specific requirement is creating blocks without purchasing ACF Pro. Visual control configuration still leaves template development to you.

Advanced Custom Fields

Advanced Custom Fields provides a free toolkit for structured fields, post types, and taxonomies. That is useful for organizing site data, but it doesn’t make ACF Free a custom-block library.

Important paid boundary: ACF Blocks is an ACF Pro feature. If you want PHP-rendered custom blocks built through ACF’s block framework, a Pro license is required.

Choose it for: Free content modeling where the fields themselves are the requirement. It is included here as a supporting developer tool, not as a recommendation for free custom-block creation. Compare Lazy Blocks for that separate task.

Blocks Animation

Blocks Animation adds CSS animation settings to the block settings sidebar. It is useful when your existing blocks already provide the layout and content, but you want to introduce movement.

Choose it for: Adding animation controls without changing the page’s main block library. The plugin is free, and its source is maintained within the Otter Blocks project.

Before adding it, check whether your existing suite already covers the motion you need. Keep important content readable without animation and review the resulting behavior on smaller screens and with reduced-motion preferences.

Create Block Theme

Create Block Theme is a theme-authoring utility. It can create a blank theme, clone an active theme, create a child theme or style variation, and export theme work that includes changes made in the WordPress Editor.

Choose it for: Turning Site Editor work into theme files that can be saved and moved. It is not a library of ready-made content blocks.

Free scope: The plugin is free. Its documentation explicitly warns that saving can make permanent changes to the active theme or site, so use a development copy and retain backups before writing changes to theme files.

Gutenberg

The Gutenberg plugin gives early access to editor development ahead of inclusion in WordPress core. It is different from the stable block editor already bundled with WordPress.

Choose it for: Development, compatibility testing, and exploring upcoming editor features. You do not need to install it simply to use blocks, and it is not a replacement for a content-block library.

Free scope: The plugin is free, with experimental and evolving functionality. For a regular site that only needs better layouts, tables, or forms, start with the built-in editor and the relevant specialist plugin instead.

How to choose a workable plugin combination

Start with one representative page. For a service business, that might need a responsive introduction, a service section, testimonials, and an enquiry form. Compare Kadence Blocks with Stackable against those requirements before adding more tools. If the chosen suite’s form covers the enquiry, a separate form builder may be unnecessary.

For a publication, begin with the built-in editor and add Ultimate Blocks when you need article navigation or content toggles. Add Flexible Table Block or Syntax-highlighting Code Block only if your content requires their specific capabilities. A blog doesn’t automatically need a full page-building suite.

For a custom site, compare GenerateBlocks’ structural controls and queries with the output you need. Bring in Lazy Blocks for a component that needs its own editing fields and template. Use ACF Free for structured data only when that is part of the plan; budget separately if ACF Blocks is the intended implementation.

Before committing, reproduce a real section using the free edition, check its mobile output, and confirm that required features aren’t marked Pro. Also check what happens to a copy of the page when the plugin is deactivated. Those checks answer more useful questions than a total block count, and they keep the choice tied to the site you’re actually building.
