[Request for feedback] Adding shared performance insights to Lighthouse

[connorjclark]

(more detailed blog post coming in a few days, will update this post then)

The Performance panel in Chrome DevTools recently added insights to the trace view. These performance insights are powered by a trace analysis library that was designed to also run in Lighthouse. The performance insights are analogous to existing Lighthouse performance audits, but with some tweaks and consolidation. The goal is to offer the same performance advice across all our performance tools - Chrome DevTools, Lighthouse and PageSpeed Insights.

In Lighthouse, the set of performance audits that have been replaced by equivalent insight audits will be removed.

• v12.6.0 (soon to be released): display a toggle in the Performance section to switch from audits to insights. Defaults to existing audits
• v12.x (~June 2025): change the default from "audit mode" to "insight mode"
• v13 (~October 2025): remove the toggle and drop the original performance audits
