About Hronaut
Hronaut is a desktop browser designed for AI coding agents, providing persistent workspaces that retain tabs, cookies, and local storage between tasks. It allows developers to test web apps, maintain project sign-ins, and resume the same workspace across multiple agent sessions. The tool supports human oversight by enabling users to pause agent access, handle logins or 2FA manually, and then resume agent work within the same session. Workspaces can be named and organized separately, keeping project accounts and tabs distinct for clarity. Hronaut integrates with existing coding agents through MCP, offering browser inspection, debugging, and debugging tools within a single application. It runs locally on Windows, macOS, and Linux, ensuring direct access to localhost apps and local development environments.
