Spectra Legacy – Gutenberg Blocks
About Spectra Legacy – Gutenberg Blocks
This plugin was previously called Spectra. It’s now Spectra Legacy. Nothing on your website has changed.
Your blocks, pages, settings, and content all continue to work exactly as they did before. There’s nothing to migrate and nothing to configure.
Spectra Legacy vs. Spectra Blocks
We’ve split Spectra into two products.
Spectra Legacy is this plugin — built for existing Spectra users. It receives security and compatibility updates and full support, but no new features. Spectra Blocks is a new, separate plugin where all new feature development happens, aimed at new installs and anyone who wants ongoing additions. If you’re already using this plugin, no action is needed; installing Spectra Blocks is entirely optional whenever you’re ready.
If you’re already using this plugin, you don’t need to do anything. If you want new features as they’re released, you can install Spectra Blocks separately, whenever you’re ready. There’s no deadline and no required migration.
What’s included
Spectra Legacy includes the full block library your site is already built on: layout tools, content and post blocks, form and SEO blocks, social blocks, and site tools like Popup Builder and Coming Soon mode.
Blocks included

How Sourcemap Explorer detects Spectra Legacy – Gutenberg Blocks
Spectra Legacy – Gutenberg Blocks sits at v2.20.1 with 1.0M+ active installs, a 4.7/5 rating from 1,869 reviews, tested up to WordPress 7.0.2. Its last wp.org update landed 2026-07-31 1:47pm GMT, and it has been on the directory since 2018-06-13. Whatever the install count, every site running it serves the plugin's files from the same predictable location — and that is the signal Sourcemap Explorer reads.
WordPress plugins all load assets from a predictable path: /wp-content/plugins/<slug>/. Sourcemap Explorer enumerates every such URL on the rendered page (script tags and stylesheets) and pulls the version from the ?ver= cache-buster query parameter when WordPress emits one. The slug is then cross-referenced against the wordpress.org plugin directory to attach the human-readable name, author, install count, rating and changelog you see on this page.
- 1
Find /wp-content/plugins/ultimate-addons-for-gutenberg/ in the Network tab
Open DevTools → Network → reload the page. Filter by "JS" or "CSS" and look for asset URLs starting with `/wp-content/plugins/ultimate-addons-for-gutenberg/`. Each match confirms the plugin is loading on the page. Sourcemap Explorer enumerates every plugin path automatically and lists each one in the popup's Stack tab.
- 2
Read the version from the ?ver= query string
WordPress appends the plugin version as a cache-busting query parameter to its asset URLs (`?ver=2.20.1`). Sourcemap Explorer pulls this version directly. The version on this page (2.20.1) is the latest published on wp.org — the version on a real site may lag.
- 3
Cross-reference with wp.org for human-readable metadata
Once the plugin slug is identified, fetch `https://api.wordpress.org/plugins/info/1.2/?action=plugin_information&request[slug]=ultimate-addons-for-gutenberg` to read the human-readable name, author, install count, rating and changelog. This page already does that for you.
Plugin ecosystem context
A Gutenberg block library or block-based theme companion. Plugins in this category extend the WordPress block editor with additional blocks; their assets load on the frontend whenever the page renders blocks they registered. Within that group, Spectra Legacy – Gutenberg Blocks (1.0M+ active installs) is tagged block, blocks, editor, gutenberg on wp.org.
Installation
Install through the WordPress plugin directory, or upload the plugin files to wp-content/plugins and activate from your dashboard.
If you’re already running this plugin, no action is needed — it updates automatically like any other plugin.
FAQ
We split Spectra into two products: Spectra Legacy (this plugin, for existing users) and Spectra Blocks (a new plugin for future development). The rename reflects that split — it doesn’t change how this plugin works.
No. This is a naming change, not a functional one. Your site continues to work exactly as before.
No. Spectra Legacy is fully backward compatible with everything built using the plugin before the rename.
No. There’s no required migration and no deadline. Spectra Blocks is a separate, optional plugin. You can keep using Spectra Legacy indefinitely.
Yes. It continues to receive security updates, compatibility fixes for new WordPress and PHP versions, and standard support.
Spectra Legacy is the version you already have — stable and unchanged in how it works. Spectra Blocks is where all new features are being built going forward. See the comparison above.
Yes — and during a transition, most people do. Existing pages keep working on Spectra Legacy while you build new pages in Spectra Blocks. Each plugin only loads assets for the blocks a given page uses, so running both isn’t a heavy performance tax. It’s not meant to be a permanent setup: once your site no longer has any Legacy blocks, you can deactivate Spectra Legacy.
It’s now called ZipAI. It still works in Spectra Legacy. New AI features are being developed in Spectra Blocks.
Yes, same as before — no restrictions.
