Overview

Browserr is a browser engine made for AI agents, shipped as one binary built on Servo and SpiderMonkey rather than Chromium or the Chrome DevTools Protocol. Agents read pages as structured text and elements, click and fill whole forms by selector, wait for single-page apps to be ready and catch failures instead of hanging. It stops when it is unsure, hands the page to a person when a human is needed, holds payment submits behind a confirm step and keeps a log and network record of everything it did. It comes with an MCP server and SDK and runs on Windows, Linux and macOS; it is an early release. You get a browser your agent can drive, with a record of every action it took.
