The block editor is WordPress’s future, and Spectra Pro is Brainstorm Force’s bet on it — a rebuilt-from-core block suite with AI page generation, a popup builder, global styles, and design extensions on top of a lean set of flexible blocks. Where the original Spectra (now “Spectra Legacy”) shipped dozens of single-purpose blocks, Spectra Blocks takes the composable approach: fewer blocks, more Extensions, everything stored as standard block markup — no shortcodes, no lock-in.
For agencies, the recent White Label support and the Zip AI companion make it a serious Elementor alternative: describe the page you want, get a native-block first draft, and hand clients a site that edits in the editor WordPress already gives them.
Competitive Features
- AI page and section generation. Zip AI generates full-page or per-section drafts (hero, pricing, FAQ, testimonials) as native blocks, plus AI copy rewriting in place.
- HTML-to-blocks conversion. Convert an existing HTML page into editable native Spectra blocks.
- Popup Builder. Build popups with the same native blocks, cookie-based display rules, and interaction fixes tracked across releases.
- Extensions system. Advanced spacing, border, shadow, and responsive controls layered onto flexible blocks.
- Global Styles. Site-wide colors, typography, and spacing set once — with Style Guide color sync to Astra themes.
- Design Library. Ready-made patterns — info boxes, testimonials, pricing tables, comparisons — built entirely from Spectra blocks.
- White Label (Pro). Rebrand Spectra Blocks Pro from dedicated settings for client handovers.
- Container block. Nest core, Spectra, and third-party blocks for any custom layout.
Key Features
- Responsive correctness. Per-device settings honor core breakpoints across editor and front end on WordPress 7.1, and nested blocks (like those in a Post carousel) respect Slides Per View and Space Between on every breakpoint.
- Valid markup discipline. Buttons output valid HTML; AI-created text blocks no longer flag as invalid; image srcset, sizes, and decoding attributes survive inside Spectra blocks.
- Third-party embeds. URL-based embeds — Calendly, Trustindex, booking widgets — work correctly inside Spectra blocks.
- Version rollback. Roll back to a previous version from the dashboard (Settings → Utilities → Version Control).
- Login block security. Nonce verification strengthened, and the login_redirect filter applies correctly for plugin compatibility.
- Global Styles integrity. Custom classes keep their CSS variable values on save.
- Popup interaction fixes. Cookie-hidden popups no longer block page interaction; duplicate popup assets removed.
- Performance thinking. Dynamic assets load on demand — the composable architecture exists partly to ship less JavaScript.
Comparison with Competitors
Spectra Pro vs GenerateBlocks Pro
| Feature | Spectra Pro | GenerateBlocks Pro |
|---|---|---|
| Block model | Flexible blocks + Extensions | Fewer primitives, deep controls |
| AI generation | Zip AI built in | No |
| Popup builder | Yes | No |
| Design tokens | Global Styles | Yes, with dashboard |
| Editor access | White Label focus | Granular access controls |
| Best for | Fast AI-assisted building | Performance-disciplined builds |
GenerateBlocks Pro is the minimalist system. Spectra Pro adds AI generation and popups — more product, less purity.
Spectra Pro vs Kadence Blocks Pro
| Feature | Spectra Pro | Kadence Blocks Pro |
|---|---|---|
| AI features | Zip AI page/section generation | Limited |
| Block count | Smaller set + Extensions | Larger catalog |
| Popup builder | Yes | Via separate plugins |
| Ecosystem | Astra/Starter Templates | Kadence theme suite |
| Markup | Native core-block APIs | Native blocks |
Kadence ships breadth. Spectra Pro’s rebuild-on-modern-APIs approach and AI companion are its current differentiators.
Recommended Stack — Spectra Pro pairs naturally with its Brainstorm Force siblings: Astra Pro Addon as the theme layer and Astra Premium Sites for starter designs, with WP Rocket caching the output.

- Fix: Button text alignment now applies correctly in the editor.
Frequently Asked Questions
Is Spectra Pro the same as the original Spectra plugin?
The original Spectra is now called Spectra Legacy and continues with maintenance updates. Spectra Blocks (the product behind Spectra Pro) is a separate, rebuilt plugin based on WordPress’s modern core-block APIs — you move to it when it makes sense, not because you must.
How does the AI generation work?
Zip AI, the companion plugin, generates complete page drafts or individual sections from a text prompt, converts existing HTML pages into native blocks, and rewrites copy in place. Everything generates as standard block markup you edit normally.
Do I need a page builder with it?
No. Spectra Blocks is built for the native block editor — no separate builder interface, no proprietary layout system, and your content stays as standard block markup.
Does it include a popup builder?
Yes. Popups build with the same native blocks, with display rules, cookie behavior, and interaction fixes tracked across recent releases.
Can agencies rebrand it?
Yes. White Label settings let you rebrand Spectra Blocks Pro for client sites.
Is the GPL version the full Pro plugin?
Yes. The download includes all Pro features for unlimited sites under the GPL license.
