Best Gutenberg Block Plugins for WordPress in 2026

One of the most underrated advantages of the WordPress block editor is extensibility. You’re not limited to the default blocks that ship with Gutenberg — you can install dedicated block plugins to unlock advanced layouts, styled content sections, pricing tables, testimonials, and much more.

In practice, a good block plugin can make the editor feel closer to a full page builder, without adding the bloat or lock-in that comes with tools like Elementor or Divi.

To help you find the right options, here’s a rundown of the best Gutenberg block plugins worth installing in 2026.

The Best Gutenberg Block Plugins to Expand the Editor

Kadence Blocks

Kadence Blocks is one of the most capable block plugins available — and it’s free. Its standout feature is the Row Layout block, which lets you build custom multi-column layouts and control column widths by dragging and dropping. You can also set backgrounds, borders, and responsive behaviour at the row level.

Beyond the Row Layout block, Kadence Blocks adds a strong set of content blocks:

• Advanced Heading
• Advanced Button
• Icon and Icon List
• Info Box
• Accordion
• Tabs
• Spacer / Divider
• Form (built-in contact form block with conditional logic in the pro version)

Kadence has grown significantly since it was first released and now pairs well with the full Kadence theme ecosystem, though the blocks work with any theme.

Spectra (Ultimate Addons for Gutenberg)

Originally called Ultimate Addons for Gutenberg, this plugin is now branded as Spectra by Brainstorm Force — the same team behind the Astra theme. It’s one of the most actively maintained block plugins in the ecosystem.

Spectra covers both layout and content:

• Advanced Columns and Container blocks for flexible layouts
• Advanced Heading with custom typography controls
• Call to Action
• Marketing Button
• Post Grid, Carousel, and Masonry layouts for displaying blog posts
• Testimonials
• Team Members
• Price List
• Content Timeline
• Form styling for Contact Form 7 and Gravity Forms

The free version is generous. A pro version adds popup builder, custom fonts, and additional block controls.

Stackable

Stackable was one of the earliest block plugins for Gutenberg and has continued to evolve with the editor. It offers 30+ blocks across layout and content categories, including:

• Counter
• Testimonial
• Team Member
• Video Popup
• Pricing Box
• Feature Grid
• Call to Action
• Posts Block
• Timeline

You can preview all blocks at the Stackable website.

One of Stackable’s strengths is its design system — blocks share a consistent visual language and integrate with its global colour and typography settings. The premium version adds hover effects, a CSS customiser, and additional layout presets. Pricing starts at $49/year for a single site.

CoBlocks

CoBlocks is a polished set of layout and content blocks, now maintained by GoDaddy as part of the Go theme ecosystem — though it works equally well with any WordPress theme.

Its resizable row/column block gives you granular layout control, and the Shape Divider block is particularly useful for creating visual section breaks with custom SVG shapes.

Other highlights include:

• Shape Divider
• Media Card
• Author Profile
• Click to Tweet
• Pricing Table
• Dynamic Separator
• Food & Drinks (useful for restaurants and hospitality sites)

CoBlocks is completely free with no premium upsell.

Otter Blocks

Otter Blocks, developed by ThemeIsle, has matured into a genuinely capable plugin. It combines a useful set of blocks with a pattern/template library you can insert directly into the editor.

Key blocks include:

• Section — flexible column layouts with template library access
• Testimonials
• Pricing Table
• Progress Bar and Circle Counter
• Review block (useful for affiliate and review content)
• Product Review (with schema markup for rich results)
• Plugin Card — pulls live data from WordPress.org listings

The pro version adds AI-powered content generation blocks, WooCommerce blocks, and a form builder with conditional logic.

Lazy Blocks

Lazy Blocks works differently from everything else on this list. Rather than adding pre-built content blocks, it gives you a visual interface to build your own custom Gutenberg blocks — without writing a single line of JavaScript.

You define the fields your block needs (text, image, select, toggle, etc.), then use a simple HTML/PHP template to control how those fields render on the frontend.

If you’ve used Advanced Custom Fields (ACF) for custom post types, the workflow feels familiar. Basic HTML and CSS knowledge is enough to get started. It’s an excellent option for developers building client sites where content editors need custom, structured blocks without the complexity of React development.

Blocksy Companion

Note: Atomic Blocks (the original plugin in this slot) was discontinued and merged into the Genesis Blocks plugin by WP Engine. For most users, Blocksy Companion is now the better recommendation in this category.

If you’re using the Blocksy theme, the Companion plugin extends it with additional blocks and site-builder features. For general use, Genesis Blocks (the successor to Atomic Blocks) remains available at WordPress.org and covers basics like:

• Pricing
• Post Grid
• Testimonial
• Accordion
• Call to Action
• Author Profile
• Drop Cap
• Newsletter opt-in

FooGallery

FooGallery is a dedicated gallery plugin that works well with Gutenberg and is designed specifically for showcasing images. It’s a strong fit for photographers, portfolios, and image-heavy sites, with gallery layouts such as:

• Grid Gallery
• Masonry Gallery
• Justified Gallery
• Slideshow Gallery

If your clients regularly publish image-heavy content and the default WordPress gallery block isn’t enough, FooGallery is a great option to consider.

Which plugin should you choose?

The right plugin depends on what you need:

If you want a solid all-rounder with great layout controls, start with Kadence Blocks — it’s the most actively developed free option in 2026 and works with any theme.

If you need a comprehensive content block library with post display options, Spectra is a strong choice, especially if you’re already in the Astra/Brainstorm Force ecosystem.

If you’re building client sites and need custom structured blocks without React development, Lazy Blocks is the most efficient tool for the job.
