What Gutenberg Block Plugins Do
Gutenberg block plugins extend WordPress's built-in editor with additional blocks, templates, and advanced features. Below are the main capabilities to look for. Per-plugin support for each capability is shown in the matrix above.
Expand Your Block Library
Buzzwords: Gutenberg Blocks, Gutenberg Widgets.
Beyond default WordPress blocks, Gutenberg block plugins add unique blocks that let you add sliders, accordions, boxes, advanced galleries, and more.
Templates & Starter Sites
Buzzwords: Pre-built sites, Gutenberg templates, Pattern library.
Templates are pre-designed sections or pages you can insert and customize. Starter sites go further — they import a complete, multi-page website with content and design already in place, giving you a working foundation rather than a blank canvas.
Dynamic Content
Buzzwords: Custom fields, Post meta, Dynamic tags, Field binding.
Dynamic content lets you build a single template — for a post type, an archive, a product page — and populate it with different data per entry. Design the layout once; the blocks pull in the right title, image, or field for each item automatically.
Loop Builder
Buzzwords: Query loop, Post grid, Custom queries, Archive templates.
A loop builder lets you design a layout for a single post or item, then apply it automatically to every item in a list. You control what shows up, in what order, and can filter by category, tag, custom field, or any other criteria.
AI Features
Buzzwords: AI generation, Layout AI, Content writing, AI templates.
AI in block plugins can mean generating text, images, or entire page layouts from a prompt. Some plugins generate full page layouts from a description — solving the blank-page problem entirely. Others focus on text and image generation, letting you write copy and create visuals without leaving the editor.
Custom Post Types & Fields
Buzzwords: CPTs, Custom taxonomies, Custom fields.
WordPress ships with posts and pages. Custom post types let you add your own content structures — properties, events, team members — each with their own fields and taxonomies to keep everything organized and queryable.
What They Look Like
Conclusion
All three plugins are WPML-compatible and work well for multilingual sites. For standard page building, Essential Blocks offers the most generous free tier, while Spectra adds a built-in AI layout generator that's hard to match at its price. If your site needs structured custom content — post types, fields, and queryable data — Toolset is in a different category entirely and is the only option here built specifically for that use case.
