Calibre vs OpenHouse: at a glance
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 OpenHouse?
OpenHouse adds time-zone-aware retention and per-database table caps.
OpenHouse ships small versioned releases straight from merged pull requests. On November 13 it shipped five: retention policies on string date columns can now take a time zone, operators can cap live tables per database with metrics on usage and rejections, view requests and operations are now audited in full, and two fixes make view property SET/UNSET and REPLACE behave. Earlier in November failed Spark maintenance jobs began exiting as failed.

◆ 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.
OpenHouse
5.0ANALYTICS
OpenHouse adds time-zone-aware retention and per-database table caps.
◆ Current state
OpenHouse ships small versioned releases straight from merged pull requests. On November 13 it shipped five: retention policies on string date columns can now take a time zone, operators can cap live tables per database with metrics on usage and rejections, view requests and operations are now audited in full, and two fixes make view property SET/UNSET and REPLACE behave. Earlier in November failed Spark maintenance jobs began exiting as failed.
◆ Where it's heading
OpenHouse is adding the controls a shared lakehouse needs at scale: quotas, audit trails and retention that matches business calendars. Views are getting the same governance tables already had.
◆ Prediction
Expect more views milestones after audit (the release is labeled Views M1), and further operator controls for quotas and maintenance.
