Oxygen vs Spectra: at a glance
What is Oxygen?
Oxygen 6.2 beta adds an MCP server, making the WordPress page builder AI-agent controllable
Oxygen is deep in the 6.2 beta cycle (now at Beta 8), with the headlining feature being an MCP Server — meaning AI agents can directly drive Oxygen's page builder via the Model Context Protocol. Alongside the beta track, stable releases 6.1.2 and 6.1.3 addressed a security issue in the Design Library import flow and a regression fix. The 4.9.8 RC 1 branch keeps the legacy Classic version compatible with WooCommerce 11.
What is Spectra?
Spectra Blocks ships White Label support and WordPress 7.1 compat as post-Pro-launch stabilization continues
Spectra Blocks is in a high-cadence patch cycle following the July launch of its Pro tier, shipping releases across both the free plugin and Pro variant in parallel. Most updates are bug fixes and compatibility patches, but 1.0.7 adds White Label support — a capability that signals agency market positioning. The product launched Pro just two months ago and is still ironing out the foundational plumbing (Global Styles, Style Guide Color Sync, theme color integration).

Oxygen
6.3DESIGN
Oxygen 6.2 beta adds an MCP server, making the WordPress page builder AI-agent controllable
◆ Current state
Oxygen is deep in the 6.2 beta cycle (now at Beta 8), with the headlining feature being an MCP Server — meaning AI agents can directly drive Oxygen's page builder via the Model Context Protocol. Alongside the beta track, stable releases 6.1.2 and 6.1.3 addressed a security issue in the Design Library import flow and a regression fix. The 4.9.8 RC 1 branch keeps the legacy Classic version compatible with WooCommerce 11.
◆ Where it's heading
The MCP Server is the most directional move Oxygen has made in recent history. Once GA, it puts Oxygen in the category of AI-agentic design tools — a page builder that an LLM can compose, edit, or debug programmatically. Beta 3's UI localization signals that international market expansion is happening in the same release, broadening the addressable user base alongside the AI capability.
◆ Prediction
Oxygen 6.2 GA is the immediate next move; the question is whether MCP integration depth expands post-launch to cover template generation, responsive breakpoints, and component discovery — the scenarios where AI-driven page building would actually save time.
Spectra
5.0DESIGN
Spectra Blocks ships White Label support and WordPress 7.1 compat as post-Pro-launch stabilization continues
◆ Current state
Spectra Blocks is in a high-cadence patch cycle following the July launch of its Pro tier, shipping releases across both the free plugin and Pro variant in parallel. Most updates are bug fixes and compatibility patches, but 1.0.7 adds White Label support — a capability that signals agency market positioning. The product launched Pro just two months ago and is still ironing out the foundational plumbing (Global Styles, Style Guide Color Sync, theme color integration).
◆ Where it's heading
Spectra Blocks is executing the standard WordPress plugin growth arc: stable free tier as the lead-gen layer, Pro tier for agencies and advanced users. White Label support in the free tier is unusual — it typically lives behind a paywall — and suggests Astra (the parent company) may be bundling or upselling Spectra inside agency bundles. The fixes-heavy cadence suggests early adopters are stress-testing the plugin in real sites; stability is the current priority over new features.
◆ Prediction
The fix cycle looks close to wrapping up given five consecutive patch releases. The next move is almost certainly new blocks or template content in the 1.1.x range to give the Pro tier a reason to upgrade beyond the foundation that just shipped.
