About

FastBrowse is an open-source browser automation agent that executes web tasks by indexing page controls and selecting actions via an AI model. It ensures verifiable results by citing verbatim quotes from the page in its answers and validates structured output against schemas. The tool keeps sensitive credentials out of model prompts by resolving them via scoped secrets or integrations like Bitwarden. It supports multiple execution environments, including local Chrome, a hosted browser pool, and cloud browsers, and integrates with AI coding assistants like Claude Code and Codex through MCP and skills.
