Agent Browser

Agent Browser is Vercel Labs' browser-automation CLI for agents. README now leads with a native Rust binary. Install is npm install -g agent-browser then agent-browser install (Chrome for Testing), or Homebrew / Cargo. The CLI is $0. Chrome, not a hosted browser seat, is what you run.

Compare Playwright if you wanted Microsoft's automation library, Cloudflare Computer if you wanted a hosted computer preview, and Cline if you wanted an editor agent that can call a browser tool.

Key Features

Snapshot then click refs: agent-browser snapshot returns an accessibility tree with @e1 refs. Clicks and fills use those refs. Traditional CSS / role selectors still work.
Rust first, source build is heavier: Global npm / Homebrew / Cargo install the native binary. Building from source wants Node.js 24+, pnpm 11+, and Rust. Do not call Node the runtime for the recommended install.
Chrome for Testing: First-time agent-browser install downloads Google's automation Chrome. Existing Chrome, Brave, Playwright, and Puppeteer installs are detected. Linux can add --with-deps.
Not a Vercel dollar SKU: The repo is Apache-2.0. We did not find a public hosted-browser price on the README on the public page.

Use Cases

People wiring a coding agent to a real page who want refs instead of brittle selectors.
People comparing Agent Browser vs Playwright after they see 40,767 stars vs Playwright's library API.
People who still think the product is a Node fallback CLI.

Limitation: We did not re-audit every command (pdf, annotate, CDP, serverless Chromium). Quality depends on the page and the agent that calls the CLI.

Pricing

github.com/vercel-labs/agent-browser on 2026-08-17.

Piece	Price	Notes from first-party pages
agent-browser CLI	$0	Apache-2.0. 40,767 stars.
Chrome for Testing	Downloaded locally	`agent-browser install`.
From source	$0 + toolchain	Node 24+, pnpm 11+, Rust.

If a leftover page still says Node fallback is the product, treat this README as the source.

Getting Started

npm install -g agent-browser then agent-browser install.
agent-browser open example.com and agent-browser snapshot.
Click with @e2 from that snapshot, not a remembered selector.
Confirm Playwright if you wanted a library instead of a CLI.

Frequently Asked Questions

Is it still a Node CLI with a Rust option?

Recommended install is the native Rust binary. Node 24+ is for building from source.

Same as Playwright?

No. Playwright is a library. This is a CLI with snapshot refs for agents.

Is there a hosted Vercel price?

Not on the README on the public page. The software is Apache-2.0.

Alternatives

Playwright: Microsoft browser automation, now with agent/MCP docs.
Cloudflare Computer: Hosted computer preview, not this local CLI.
Cline: Editor agent that can drive tools, including browsers.

Tips

Quote 40,767 stars and Apache-2.0 from the GitHub check.
Quote snapshot + @eN refs, not a Node-fallback census.
Confirm agent-browser install before you assume system Chrome is enough.

Conclusion

Agent Browser is Vercel Labs' Apache-2.0 Rust CLI with 40,767 stars, not a Node-fallback product. Start at github.com/vercel-labs/agent-browser, then decide whether Playwright already covers the automation API you need.
