Calibre vs Dovetail: 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 Dovetail?
Channels 2.0 is now the default, and Dovetail is pulling feedback sources up a level.
Channels 2.0 reached general availability on October 21 as the standard Channels experience for every Dovetail customer, after a closed beta in July and an open beta in September. Each idea now has an activity log, and saved views open with a snapshot of ideas, evidence, sources and top activity. Sources entered beta, aimed at the per-project integration setup that teams had to repeat. Chat now opens beside work, and default contact fields address the mapping that CRM sync and revenue rollups depend on.

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.
Dovetail
5.0ANALYTICS
Channels 2.0 is now the default, and Dovetail is pulling feedback sources up a level.
◆ Current state
Channels 2.0 reached general availability on October 21 as the standard Channels experience for every Dovetail customer, after a closed beta in July and an open beta in September. Each idea now has an activity log, and saved views open with a snapshot of ideas, evidence, sources and top activity. Sources entered beta, aimed at the per-project integration setup that teams had to repeat. Chat now opens beside work, and default contact fields address the mapping that CRM sync and revenue rollups depend on.
◆ Where it's heading
With GA done, attention has moved from what an idea is to what feeds it and who can trust it. Sources makes data connection an account-level concern, and default fields remove a setup step in front of revenue rollups. Activity logs and snapshots add the accountability a roadmap discussion needs. Each change pulls Dovetail toward a shared system for product teams, away from a project-by-project research tool.
◆ Prediction
Sources leaving beta is the next visible milestone, given how much of the October work depends on connected data. Status flowing back from Jira or Linear remains absent from the entries.
