How does Unbrowse work?

Unbrowse is the API layer for AI agents. The first time your agent visits a website, Unbrowse captures the real APIs the site uses to render itself. The next call skips the browser entirely, sub-500ms direct API instead of multi-second pixel-clicking. The shared marketplace already covers 600+ domains, so most calls are instant on first try. Open source, runs locally, plugs into OpenClaw, Claude Desktop, Cursor, and any MCP-aware framework.

How much faster is Unbrowse than headless browser automation?

Unbrowse is roughly 100x faster per page than headless browser automation. Headless browsers take 5 to 30 seconds per page interaction; Unbrowse makes direct API calls in 50 to 200 milliseconds, and uses about 200 tokens per action against 8,000 tokens for scraped HTML. Speed compounds because the shared marketplace already covers 600+ domains, so most calls are instant on first try without re-discovery work. For agent loops where the web step is the bottleneck, that turns minutes of work into seconds.

Yes. Unbrowse is 100% free and open source under the AGPL-3.0 license. There are no paid tiers, cloud proxies, or usage credits. Everything runs locally on your machine.

What websites does Unbrowse support?

Unbrowse works with any website that uses APIs to render its frontend, which covers most modern web applications. 600+ domains and 18,000+ endpoints are in the live marketplace today, including Airbnb, LinkedIn, x.com, Reddit, and hundreds of others. When a site cannot be reverse-engineered, Unbrowse falls back to standard browser automation so the agent never gets stuck. The list grows on its own: every new capture adds a domain and helps the next agent on the same site.

Is Unbrowse secure? Do my credentials leave my machine?

Unbrowse runs entirely locally and your credentials never leave your device. There are no cloud proxies, no man-in-the-middle interception, browser cookies stay on your machine, and authentication credentials are encrypted with AES-256-CBC in a local vault. Only discovered API endpoint patterns (URL templates and schemas, never your data or credentials) are shared with the registry, and only when you opt in via `unbrowse mode`. That makes Unbrowse safe to install on a work machine without changing your existing security posture.

How do I install Unbrowse?

Run npx unbrowse setup --mcp for one-command installation that registers the Unbrowse MCP server with Claude Code, Claude Desktop, Cursor, Windsurf, Codex, or OpenClaw. For Claude Code: claude mcp add unbrowse -- npx -y unbrowse mcp. For other clients, add {"unbrowse": {"command": "npx", "args": ["-y", "unbrowse", "mcp"]}} to your mcp.json and restart the host.

What is the skill registry?

The skill registry is a shared marketplace of reverse-engineered API skills. When one agent discovers how to interact with a website's API, the result is published so every other agent can call those endpoints without re-discovering them. Value compounds because every new capture lowers the cost for the next agent that needs the same data, the way Wikipedia gets more useful with every edit. That is what turns Unbrowse from a per-agent tool into shared infrastructure for the agent web.

## After You Install

Bypass the DOM completely.

Speed

Skip the rendering engine

Headless browsers are slow and flaky. Unbrowse taps directly into the hidden shadow APIs that power the frontend, returning data instantly.

100xfaster per page

5-30s headless→50-200ms API

Tokens

40x fewer tokens

Why burn context on 8,000 tokens of HTML? Your agent gets the exact JSON data it needs — nothing else.

Scraping HTML~8,000t

Direct API~200t

Discovery

Auto-discovers APIs

Your agent calls Unbrowse over MCP and the right shadow endpoint comes back — schemas, parameters, sample values, all ready to call.

Zero config needed

Shared skill registry

Security

Integrate with anything. Behind auth.

No cloud proxies, no expensive credits. Unbrowse runs locally, leveraging your actual browser sessions to securely access auth-protected content.
