Calibre vs OpenMetadata: at a glance
What is Calibre?
Lighthouse 13.6 shifts Calibre's scores and adds audits for how AI agents read your pages
Calibre's Test Agents moved to Chrome 156 and Lighthouse 13.6.0, which fixes how simulated throttling calculates LCP and FCP, so scores on PageSpeed Desktop and PageSpeed Mobile Test Profiles should mostly improve with no site change. Snapshots also gained Lighthouse's Agentic Browsing audits, covering the accessibility tree, WebMCP, llms.txt and ARD manifests, a category Google marks as under development. In September the free Core Web Vitals Test added four experimental CrUX ad metrics. August's work attached deployment markers to RUM charts and added all-pages Synthetic aggregates.
What is OpenMetadata?
OpenMetadata reaches 2.1 rc1 after a month of repairing 2.0's connectors.
OpenMetadata has shipped a run of 2.0.x maintenance releases, each centered on connectors, lineage and search. 2.0.3 included a certificate-verification bypass fix and a SQL-injection fix, 2.0.5 restored metadata affected by 2.0 ingestion regressions, and 2.0.7 improved reliability for Pub/Sub, SQL Server and Unity Catalog. The 2.1.0-rc1 pre-release has now appeared, though its notes are a commit message about settings-modal styling rather than a feature list.

Lighthouse 13.6 shifts Calibre's scores and adds audits for how AI agents read your pages
◆ Current state
Calibre's Test Agents moved to Chrome 156 and Lighthouse 13.6.0, which fixes how simulated throttling calculates LCP and FCP, so scores on PageSpeed Desktop and PageSpeed Mobile Test Profiles should mostly improve with no site change. Snapshots also gained Lighthouse's Agentic Browsing audits, covering the accessibility tree, WebMCP, llms.txt and ARD manifests, a category Google marks as under development. In September the free Core Web Vitals Test added four experimental CrUX ad metrics. August's work attached deployment markers to RUM charts and added all-pages Synthetic aggregates.
◆ Where it's heading
Calibre remains focused on explaining why a metric moved, and this release shows the hard case: the number can move because the test changed. Tracking new browser and Lighthouse data quickly is part of the product, as the same-day CrUX ad metrics showed. Agentic Browsing audits add a new question to a performance tool, whether agents can use a page, which is still early.
◆ Prediction
Expect deployment attribution to grow into alerting, since a regression tied to a commit is the natural trigger. Agentic Browsing audits should keep changing with Lighthouse, so Calibre's treatment of them depends on Google's direction.
OpenMetadata
5.0ANALYTICS
OpenMetadata reaches 2.1 rc1 after a month of repairing 2.0's connectors.
◆ Current state
OpenMetadata has shipped a run of 2.0.x maintenance releases, each centered on connectors, lineage and search. 2.0.3 included a certificate-verification bypass fix and a SQL-injection fix, 2.0.5 restored metadata affected by 2.0 ingestion regressions, and 2.0.7 improved reliability for Pub/Sub, SQL Server and Unity Catalog. The 2.1.0-rc1 pre-release has now appeared, though its notes are a commit message about settings-modal styling rather than a feature list.
◆ Where it's heading
The 2.0 launch is being paid for in connector repairs, and the cadence of roughly weekly maintenance suggests a large installed surface. Protecting user-managed metadata from bot ingestion, and multi-pod fixes in 2.0.6, point at production deployments rather than trials. The 2.1 candidate is the first sign of attention moving forward, but the published notes do not show its contents.
◆ Prediction
Expect a 2.1 release soon, with its real scope clearer once proper notes appear. 2.0.x maintenance should continue alongside it.
