    Install

    Add it to your agent

    One file, no build step. Pick the agent you use; the command drops the SKILL.md where that agent looks for skills.

    The `skills` CLI reads this repo's /skills folder and installs into every agent it detects. Pick the skill from the list it shows.

    Terminal
    npx skills add vercel-labs/agent-browser --skill agent-browser

    agent-browser

    Fast browser automation CLI for AI agents. Chrome/Chromium via CDP with accessibility-tree snapshots and compact @eN element refs.

    Install: npm i -g agent-browser && agent-browser install

    Start here

    This file is a discovery stub, not the usage guide. Before running any agent-browser command, load the actual workflow content from the CLI:

    agent-browser skills get core             # start here — workflows, common patterns, troubleshooting
agent-browser skills get core --full      # include full command reference and templates

    The CLI serves skill content that always matches the installed version, so instructions never go stale. The content in this stub cannot change between releases, which is why it just points at skills get core.

    Specialized skills

    Load a specialized skill when the task falls outside browser web pages:

    agent-browser skills get electron          # Electron desktop apps (VS Code, Slack, Discord, Figma, ...)
agent-browser skills get slack             # Slack workspace automation
agent-browser skills get dogfood           # Exploratory testing / QA / bug hunts
agent-browser skills get derive-client     # Record a HAR, derive a standalone API client for a site
agent-browser skills get vercel-sandbox    # agent-browser inside Vercel Sandbox microVMs
agent-browser skills get protected-vercel-deployments  # Access protected Vercel deployments
agent-browser skills get agentcore         # AWS Bedrock AgentCore cloud browsers

    Run agent-browser skills list to see everything available on the installed version.

    Why agent-browser

    • Fast native Rust CLI, not a Node.js wrapper
    • Works with any AI agent (Cursor, Claude Code, Codex, Continue, Windsurf, etc.)
    • Chrome/Chromium via CDP with no Playwright or Puppeteer dependency
    • Accessibility-tree snapshots with element refs for reliable interaction
    • Sessions, authentication vault, state persistence, video recording
    • Specialized skills for Electron apps, Slack, exploratory testing, cloud providers

    Observability Dashboard

    The dashboard runs independently of browser sessions on port 4848 and can also be opened through a proxied or forwarded URL such as https://dashboard.agent-browser.localhost. Agents should stay on the dashboard origin: session tabs, status, and stream traffic are proxied internally, so session ports do not need to be exposed.
