Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 6)

Fastbrowse is a browser automation agent that uses a separate 'System One' choice model (Jev) to select actions from controls indexed on the page, avoiding invented selectors. It emphasizes cited answers, code-enforced safety gates for credentials and irreversible actions, and a Rust core with Python/Node/Go interfaces and an MCP server.

Target audience: AI engineers, backend developers, and automation developers building web agents
