Spectra Pro

The block editor is WordPress’s future, and Spectra Pro is Brainstorm Force’s bet on it – the “Spectra Blocks” generation rebuilt on top of core’s block API rather than fighting it. The free Spectra brings 25+ blocks and a Design Library; the Pro layer adds the features that make blocks genuinely compete with page builders: AI page generation with Zip AI, a popup builder, per-device CSS and JS editors, global classes, and display conditions.

This is one of the youngest products in the Brainstorm Force stable – the Pro tier (tracked here at 1.0.8, with 1.0.7-1.0.9 on the free line shipping through September 2026) is in its first year of active iteration, and the changelog shows a product finding its feet fast. Here’s the working review.

Competitive Features

• AI page generation. The AI assistant builds complete pages in the block editor – with 1.0.8 fixing the AI-created Text blocks that flagged as invalid, and 1.0.9 adding one-click access to Global Styles on AI-built pages.
• Per-device CSS, JS, and global classes (Pro). Block-level CSS and JavaScript editors with per-device settings – the customization depth that core’s block editor deliberately lacks, rendered correctly on every breakpoint (Pro 1.0.4 fixed the WordPress 7.1 responsive path).
• Popup builder (Pro). Block-based popups with triggers and conditions – replacing a standalone popup plugin inside the block editor.
• White Label support (Pro, 1.0.4). Rebrand the plugin from new White Label settings – the agency delivery option, added early.
• Style Guide with theme sync. Style Guide colors sync with Astra themes across all theme color slots, including the foreground color row (Pro 1.0.3) – theme and blocks share one design system.
• Global Styles integrity. Custom classes preserve their CSS variable (var()) values on save (1.0.6), and the classes/CSS panel works correctly in the FSE Site Editor context (Pro 1.0.2) – the design-token plumbing done right.
• Font Awesome 7 icon library (1.0.9). The icon set upgraded with automatic name mapping – existing icons keep working through the upgrade.
• Design Library. Free and premium patterns with correct “Get Access” routing (1.0.9) – the starter-design layer that makes blocks feel finished.

Key Features

• Responsive image handling. Image blocks preserve srcset, sizes, and decoding attributes inside Spectra blocks (1.0.7), with per-device size preservation fixed in 1.0.9 – responsive images survive the block layer.
• Third-party embed support. Calendly, Trustindex, and booking-widget embeds render correctly inside Spectra blocks (1.0.7) – the embed edge cases handled.
• Post carousels and sliders. Loop-driven carousels with per-device settings – the nested-block responsive settings honored on every breakpoint (1.0.8).
• Login block with hardened security. Nonce verification strengthened on the Login block (Pro 1.0.4) – the security-sensitive block given proper attention.
• Display conditions. Show/hide blocks per user state, date, or device – personalization inside the block editor.
• Valid markup discipline. Button markup validity (1.0.5) and valid AI-created Text blocks (1.0.8) – the HTML-output quality that page-builder plugins routinely botch.
• Onboarding detection. The wizard correctly detects active Pro plans – no more free-plan misidentification.
• Learn tab. In-editor guidance with Global Styles documentation – the education layer built in.

Comparison with Competitors

Spectra Pro vs GenerateBlocks Pro

The two serious Gutenberg extension platforms, with philosophically different answers.

Aspect	Spectra Pro	GenerateBlocks Pro
Block model	Many ready-made blocks	Few structural blocks
Design system	Global Styles + Style Guide	Design tokens
Custom code	Per-block CSS/JS editors	Filters and hooks
AI builder	Zip AI page generation	None
Lock-in	Moderate	Minimal

Spectra wins assembly speed – ready blocks and patterns. GenerateBlocks wins for systematic builders who want full control over markup. Both are Brainstorm-adjacent ecosystems (Spectra is Brainstorm Force; GenerateBlocks is GeneratePress’s team).

Spectra Pro vs Elementor-based addons (Royal Elementor Addons)

The editor-choice comparison: block-native versus Elementor ecosystem.

Aspect	Spectra Pro	Royal Elementor Addons
Editor	WordPress block editor	Elementor
Performance ceiling	Native blocks	Elementor’s architecture
Popup builder	Pro module	Built-in
Template library	Design Library	Frequent full-site kits

If the project is free of Elementor licensing, the Royal Elementor Addons stay the richer Elementor option; Spectra is the same ambition executed in native blocks with no builder dependency.

Recommended Stack: Spectra sites pair naturally with the same vendor’s template layer – dynamic-content sites pair Spectra’s block layer with JetEngine – custom post types and listings rendered through the same editor.

Frequently Asked Questions

Does Spectra Pro need the free Spectra too?

Yes – Pro extends the free Spectra Blocks plugin; install both. The free core carries the block library and Design Library, the Pro layer adds AI tools, popups, per-device CSS/JS, and display conditions.

Is the GPL version the full Pro plugin?

Yes. The GPL build is the complete Pro source under its original license with all features enabled. The vendor license key for auto-updates is the only absence.

Can I use it on multiple sites?

The GPL license permits unlimited installations across personal and client sites without per-domain activation – and the Pro tier includes White Label support, which makes agency deployment clean.

Does it work with any theme?

Yes – Spectra blocks work with any block theme. The Style Guide syncs most tightly with Astra (all theme color slots), but the blocks themselves are theme-independent.

What’s the per-device CSS feature?

The Pro layer adds block-level CSS and JS editors with per-device (desktop, tablet, mobile) settings – verified compatible with WordPress 7.1’s responsive editing breakpoints in Pro 1.0.4. It’s the custom-code depth core blocks never had.

Is the AI builder included?

Yes – page generation runs through Brainstorm Force’s Zip AI, integrated into the block editor. AI-created blocks received specific validity fixes in 1.0.8, showing the AI pipeline is treated as a first-class part of the product.
