Agent Browser v0.27 adds React introspection

Agent Browser v0.27 is a release for the open-source browser agent toolkit that focuses on making web automation cheaper and more inspectable. The update adds React tree and hook/state introspection, render profiling and Suspense analysis, a vitals command for LCP, CLS, TTFB, FCP, INP, SPA pushState navigation, pre-navigation init scripts, network route filtering by resource type, cURL cookie import, and reverse-proxy-friendly dashboard support.

// ANALYSIS

This is a practical infrastructure upgrade, not a flashy demo. The release targets the real pain of agentic browsing: token waste, brittle page state, and poor observability.

–React-aware inspection should make debugging modern apps far easier than screenshot-only flows.
–Web Vitals support turns the tool from "can click around" into something closer to a measurement harness.
–SPA navigation and reverse proxy support are the kind of boring fixes that usually decide whether teams can actually adopt a browser agent.
–The release looks aimed at builders who need repeatable automation, not just one-off browsing tasks.
