# Run your own Mu

When you host Mu yourself, your data never leaves your machine. No account, no sync to someone else’s server, no terms of service to accept. You get news, mail, search, weather, markets, reminders — the same tools as the web version — but they live on your hardware under your control.

The single Go binary runs on Linux, macOS, or a Raspberry Pi. You download it, point it at your mail server or API keys if you want them, and it starts. The web interface is the same one at micro.mu, just running locally. If you want to plug in a local language model instead of calling an API, you can. Your searches stay offline. Your data does not get indexed for someone else’s ad network because there is no one else.

This is work, though. You need to keep the binary updated when security patches land. You handle your own backups and uptime. If your machine goes down, your reminders don’t ping you somewhere else. You troubleshoot your own mail configuration. The hosted version handles that for you; self-hosting trades convenience for ownership.

Mu is open source under AGPL-3.0, which means you can read the code, fork it, change it. Developers can use the same API locally as the cloud version. Some people run Mu on a home server as a private family tool. Others run it on their laptop for offline access. It is not for everyone — it demands more from you — but for people who want to own their tools, it is real.
