Unbrowse turns websites into agent-ready APIs

The compelling idea is amortizing browser discovery into reusable capabilities, making web agents faster and less token-hungry. The catch is that the most important capture, replay, registry, and account infrastructure remains hosted rather than fully open source. [How Unbrowse Works](https://github.com/unbrowse-ai/unbrowse/blob/main/docs/how-it-works.md)

• –One remote MCP endpoint can expose tools across many websites, reducing the need for separate site-specific connectors.
• –Initial tasks run through a recorded cloud browser; subsequent requests replay the site’s own API over plain HTTP.
• –The project reports 3.6× mean and 5.4× median speedups versus Playwright for compiled routes. [Unbrowse homepage](https://unbrowse.ai/)
• –Internal APIs, authentication flows, anti-bot systems, and client-side logic can change, making route reliability the central engineering risk.
• –Developers should treat Unbrowse as an API acceleration layer with browser fallback, not a universal replacement for browser automation.
