Calibre vs Displayr: 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 Displayr?
Displayr's Chat can now apply and write Rules, so it changes tables as well as explaining them.
Rules, Displayr's mechanism for customizing a table's appearance and data, now work through Chat: it applies existing rules and writes custom ones, and a rule can cover every table in a document, including new ones. Two smaller additions landed with it at the end of September: document duplication through the API and a shortcut from a control to its input. Summer work made Chat auditable, with a context pill, a change summary and an Explain This button, while the core gained shared controls and rolling averages.

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.
Displayr
0.0ANALYTICS
Displayr's Chat can now apply and write Rules, so it changes tables as well as explaining them.
◆ Current state
Rules, Displayr's mechanism for customizing a table's appearance and data, now work through Chat: it applies existing rules and writes custom ones, and a rule can cover every table in a document, including new ones. Two smaller additions landed with it at the end of September: document duplication through the API and a shortcut from a control to its input. Summer work made Chat auditable, with a context pill, a change summary and an Explain This button, while the core gained shared controls and rolling averages.
◆ Where it's heading
Chat is starting to do work that changes results, which tests the auditing features built over the summer. The other track stays steady, closing gaps a long-standing survey analysis platform accumulates. API document duplication hints at more automated reporting workflows, though it is a single endpoint so far.
◆ Prediction
Expect the change summary to extend to rules Chat writes, since a rule applied across a document is harder to inspect than a single edit. Folder-scoped defaults still look like the start of broader template governance.
