Unbrowse

Unbrowse is the action engine of the internet: the open-source action layer that turns websites into reusable, indexed API routes for agents. Teach a route once by browsing, store sanitized route metadata, replay it on later calls. A replay is about 30x faster and 90x cheaper than a fresh browser session (peer-reviewed: 3.6x mean speedup, 5.4x median over Playwright across 94 live domains, 18 domains under 100ms; Internal APIs Are All You Need).

CLI quick paths (read unbrowse --help once, then stop)

The shipped CLI uses flat top-level commands. Do not prefix with build / act / eval / act — those legacy verb forms are not the primary surface.
