What it does
Hronaut is a visible desktop Chromium browser for coding agents. Named workspaces retain tabs, cookies and local storage across agent disconnects. The person can watch the browser, pause agent access and take over for manual steps.
It runs on Windows, macOS and Linux and automates pages inside Hronaut. It does not supply the coding agent or model, control native apps, or automatically attach an arbitrary existing Chrome profile. The public latest release observed September 30, 2026 was v2.8.6. Windows packages remain unsigned and macOS packages are not Apple-notarized; hashes and build attestations have a separate provenance scope.
The trial starts with the first agent tool call and lasts 10 consecutive days, with no card or automatic billing during trial. Ongoing use requires $4/month or $24/year per named user, up to three active devices. Released terms.
