What is Calibre?
Calibre MCP lets your coding agent read RUM and Lighthouse data, then fix the slow code
Calibre now ships a read-only MCP server that gives Claude Code, Cursor, Codex, Copilot, Claude and ChatGPT access to an account's RUM, CrUX and Synthetic data, included on every plan. It came days after Test Agents moved to Chrome 156 and Lighthouse 13.6.0. The latest entry is a design tidy-up that places each page's Guide link in the same top-right spot.
What is Kameleoon?
Kameleoon refines its prompt-driven personalization editor with widget, targeting, and PBX upgrades.
Kameleoon is iterating on the new Personalization editor and the prompt-based workflow that sits inside it. Recent changes: a simpler two-step widget event creation flow that ties directly to Kameleoon goals, the ability to reorder personalization targeting rules from the new editor, and PBX prompt-area improvements (resizable prompt area, image paste as input). Survey widgets get a configurable response-recording trigger.

◆ Current state
Calibre now ships a read-only MCP server that gives Claude Code, Cursor, Codex, Copilot, Claude and ChatGPT access to an account's RUM, CrUX and Synthetic data, included on every plan. It came days after Test Agents moved to Chrome 156 and Lighthouse 13.6.0. The latest entry is a design tidy-up that places each page's Guide link in the same top-right spot.
◆ Where it's heading
Calibre is turning its monitoring data into something agents act on rather than something people read in dashboards. The summer work on deployment markers, all-pages aggregates and the audit log built the context and governance an agent needs: which deploy, which page, who connected. Expect the remaining surface to follow the same path, with agents both querying performance and being measured by it.
◆ Prediction
The likely next step is write access or deploy-linked workflows over MCP, such as an agent opening a fix tied to a regression marker, since the current server is explicitly read-only and the launch frames fixing as the goal.
Kameleoon
1.3ANALYTICS
Kameleoon refines its prompt-driven personalization editor with widget, targeting, and PBX upgrades.
◆ Current state
Kameleoon is iterating on the new Personalization editor and the prompt-based workflow that sits inside it. Recent changes: a simpler two-step widget event creation flow that ties directly to Kameleoon goals, the ability to reorder personalization targeting rules from the new editor, and PBX prompt-area improvements (resizable prompt area, image paste as input). Survey widgets get a configurable response-recording trigger.
◆ Where it's heading
The product is settling into the new editor as the default surface and accumulating the small ergonomics wins teams expect from a mature personalization tool — fewer clicks, fewer manual IDs, more control over evaluation order. The PBX prompt updates suggest AI-assisted variant creation is becoming a more prominent workflow, with multimodal input now supported.
◆ Prediction
Expect the editor's PBX surface to keep gaining capability — likely brand-context awareness, reusable prompts, and broader image-driven generation. Targeting and goal flows will continue to consolidate so users don't need to reach for IDs or admin pages.
