Spectra vs Essential Blocks compares two Gutenberg block plugins that extend the WordPress block editor, so you build pages with blocks instead of a separate page builder. Spectra Pro by Brainstorm Force and Essential Blocks Pro by WPDeveloper both start with a free plugin on wordpress.org, both pull dynamic content from ACF fields, and both sell a lifetime license with updates and support for life. Both have been around since 2018 and are currently offered below their list price.
The differences lie in the focus and in the license. Spectra Pro adds building tools on top of the free Spectra blocks: a loop builder for posts and products, a popup builder with triggers, login and registration forms, scroll animations and global styles with reusable variables. Its entry lifetime plan covers 3 sites. Essential Blocks Pro unlocks premium and dynamic blocks, WooCommerce blocks and six months of Templately templates, and it sells lifetime only as one plan for 100 sites. The rows below put Spectra vs Essential Blocks side by side, so you can weigh them yourself.
In Spectra Pro vs Essential Blocks Pro, the starting point is the same. Both stay inside the native WordPress block editor, both extend a free block library that many sites already run, and both store what you build in your own WordPress database. The difference lies in what the Pro version adds on top.
Spectra Pro adds tools for building site parts: a loop builder for posts, products and custom queries, a popup builder with exit intent, delay and scroll triggers, login and registration forms, the Slider Pro and Modal Pro blocks, scroll based entrance animations and global styles with reusable variables and a font scale. Essential Blocks Pro adds blocks: more than 70 in total, including premium and dynamic blocks, WooCommerce blocks for product grids, carousels and details, global block styles and typography, and the option to switch individual blocks off to keep pages light.
Spectra Pro suits block editor users who build on a few sites and keep reaching for things the free blocks lack: post and product loops, popups with triggers, login pages and dynamic content from ACF, Pods or Meta Box. It fits teams that already work with tools from Brainstorm Force, since the larger lifetime toolkit plans add Astra Pro, premium templates and the AI platform. The free Spectra plugin counts far more active installs on wordpress.org than the free Essential Blocks.
Essential Blocks Pro suits agencies and freelancers who build many block editor sites and want one lifetime license for up to 100 of them. It also fits WooCommerce stores that need product grids, carousels and product details as blocks, and sites that show ACF fields through dynamic tags. Owners of a single small site pay for a site count they will not use, so for them the free plugin is the place to start.
Both block plugins start free on wordpress.org. The free Spectra adds extra blocks and layout options to the block editor, and the free Essential Blocks brings blocks for content, marketing, forms and WooCommerce stores. Install the free version on a staging site, rebuild one real page and see how the block settings feel in daily work before you pay.
In both cases the Pro plugin is installed next to the free one and activated with a license key, so the pages you built with the free blocks stay in place. Look at what is limited in time when you upgrade: with Essential Blocks Pro, Templately access ends after six months, while blocks, updates and support stay for life. With Spectra Pro, updates and support are included for life on every lifetime plan.
The lifetime tiers are cut very differently. Spectra Pro sells a lifetime plan for 3 sites and lifetime toolkit plans for 10 and 1,000 sites; each tier is currently offered below its regular price. Essential Blocks Pro sells a single lifetime plan for 100 sites, and its price has gone up once since we first listed it. Both vendors name a refund window of 14 days, so you can test the Pro blocks on a real project first.
Switching from one block plugin to the other is not a quick swap, because every page stores the blocks of the plugin it was built with, and the data on record describes no import path between the two. A move means rebuilding the sections that use Pro blocks. The comparison table above lists both lifetime licenses with their check date.
Each answer names the facts for both sides. Which of them matters for your project is up to you.
The entry Spectra Pro lifetime plan covers 3 sites, and lifetime toolkit plans for 10 and 1,000 sites cost more. Essential Blocks Pro has one lifetime plan, Visionary Lifetime, and it covers 100 sites; there is no smaller lifetime option.
Essential Blocks Pro includes WooCommerce blocks for product grids, carousels and product details. Spectra Pro includes a loop builder for posts, products and custom queries; the data on record names no dedicated WooCommerce blocks for it.
Spectra Pro includes a popup builder with exit intent, delay and scroll triggers, login and registration forms and a Modal Pro block. The feature list of Essential Blocks Pro does not name a popup builder or login forms, so we make no statement about them.
Spectra Pro pulls dynamic content from ACF, Pods and Meta Box. Essential Blocks Pro offers dynamic tags with ACF support; the data on record does not name Pods or Meta Box for it.
Essential Blocks Pro includes access to more than 6,000 Templately templates, which ends after six months while the blocks keep working. With Spectra Pro, premium templates come only with the larger lifetime toolkit plans.
Short answers from the vendor data. Prices and dates match the comparison above.
Spectra Pro costs $319 one-time for 3 sites, Essential Blocks Pro costs $299 one-time for 100 sites. Both are one-time payments from the vendors’ own pricing pages, checked on Oct 4, 2026.
Yes. The vendors also sell yearly plans: $69 per year for Spectra Pro and $349 per year for Essential Blocks Pro. Measured against them, the lifetime price of Spectra Pro pays off after 56 months, that of Essential Blocks Pro after 11 months.
Yes, both work without a separate page builder, because they extend the WordPress block editor itself. You add their blocks next to the core blocks, and the pages stay regular block editor content.
Yes, but it means rebuilding. Each page keeps the blocks of the plugin it was built with, and the data on record describes no tool that converts Spectra blocks into Essential Blocks or the other way round. Test the move on a staging copy and keep the old plugin active until every page is rebuilt.
For Essential Blocks Pro, yes: it lets you turn individual blocks on or off to keep pages light. For Spectra Pro, the data on record does not name such a switch, so we make no statement about it.
Both have been around since 2018. On wordpress.org the free Spectra counts far more active installs than the free Essential Blocks, while the free Essential Blocks carries the higher rating. Both free plugins were updated recently, as the product facts on the deal pages show.
This page names no overall winner between Spectra Pro and Essential Blocks Pro. In the comparison, green and red mark the better and the weaker value for each measurable point, such as price, sites and payback. The questions to weigh show which facts matter for which kind of project, so you can decide what fits yours.
