What is BrowserBash?
BrowserBash functions as a command line interface for automating web browsers using everyday language objectives. An underlying AI agent interprets the input and drives an actual browser session, producing structured output suitable for scripts or pipelines. The system defaults to free local models while allowing swaps to other engines or providers through simple flags. Users can install the package globally and execute tasks ranging from data extraction to login flows with session persistence. It includes support for multiple browser environments, secret masking in logs, and exit codes that integrate directly with continuous integration systems. Markdown based test files enable reusable and version controllable automation scripts. The design emphasizes zero cost local operation with no required signups or external dependencies for core functionality. Optional dashboard features provide run history and recordings when an account is created, but the CLI itself operates independently for privacy focused or offline scenarios.
