Brief

Vercel's agent browser is a free, full-featured browser automation and inspection tool (posted by @alxfazio on 2026-05-10) that handles UI interactions, runs JS, reads page state, manages tabs/cookies/storage/viewport/geolocation, captures screenshots/PDFs/WebM/traces/DevTools profiles, records HAR/network activity, reuses Chrome profiles, and can attach to Chrome via CDP; installable via brew or npx.

Why it matters

Vercel's agent browser is completely free (author @alxfazio, posted 2026-05-10) and supports interactive UI automation: click, type, fill forms, select options, drag/drop, upload files, run JavaScript, and read page state (text, HTML, values, attributes, URL/title).

Key details

  • It captures debugging/artifact data including screenshots, PDFs, WebM video, traces, and DevTools profiles, and can inspect/record/mock network activity including HAR logs; it also provides accessibility snapshots with element refs.
  • Chrome state can be reused via --profile or the AGENT_BROWSER_PROFILE env var and you can attach to an existing Chrome session via CDP with `agent-browser connect <port>`; install examples: `brew install agent-browser` and `npx skills add github.com/vercel-labs/agent… --skill agent-browser`.
