Hronaut gives coding agents a real, visible Chromium workspace on your own machine. Create named isolated workspaces, keep tabs and browser storage between sessions, and take over when a person must handle sign-in, 2FA, CAPTCHA, or an irreversible write. It is a local desktop app for Windows, macOS, and Linux with a local MCP connection—not a hosted browser fleet or unattended publishing service.
I built Hronaut after repeatedly hitting the gap between a text-only coding agent and a real web app: the agent needed a browser that could stay open, but login and consequential actions still needed a person. Start a named workspace, let the agent inspect or test, pause before sign-in/2FA/CAPTCHA or risky writes, take over in the same browser, then resume after checking the URL, account, and result. Feedback on setup friction, workspace boundaries, and handoff evidence is especially useful.
