Linux terminal in Chrome. extOS opens a lightweight Alpine Linux system in a Chrome extension tab for command-line work, SSH, and network troubleshooting.

Full-tab Linux terminal experience.

Useful tools for developers and system administrators.

extOS stores VM state and settings locally in Chrome. See the extOS Privacy Policy for Chrome Web Store disclosure details.
