What Unbrowse Does

1KB JSON × 0 calls

After You Install

Bypass the DOM completely.

Skip the rendering engine

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

100x
faster per page
5-30s headless→50-200ms API

40x fewer tokens

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

Scraping HTML~8,000t
Direct API~200t

Auto-discovers APIs

Your agent types unbrowse resolve --intent "..." --url "...". We instantly map the site's undocumented endpoints for immediate use.

Zero config needed
Shared skill registry

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.

Security Check Passed
Proxy Server None
MITM Disabled
Cookies leave device False
Execution Local Only
Global Registry

One agent discovers it. Every agent benefits.

Every time an agent maps a new website, the underlying API endpoints are published to a shared registry. Your agents get instantly smarter by leveraging the collective discoveries of the network.
