FAQ

Does my data leave my machine?

No. There's no cloud, no account, and no server. Everything Butin pulls is stored locally under ~/butin, and sessions are encrypted with your OS keychain. There is nowhere for it to be sent.

Do I have to log in every time I want data?

You have to log in again when the session expires — which is on the service's clock, anywhere from ~20 minutes (banks) to a few days (long-lived services). While a session is alive, Butin fetches and refreshes without any further login. See How it works.

Is Butin "hacking" or scraping services I shouldn't?

No. Butin replays your own authenticated session to read your own data — exactly what your browser does when you open the dashboard yourself. It never touches anyone else's account and stores no credentials on any server.

Does Butin store my password?

No. You sign in inside a normal browser window; Butin only keeps the resulting session, never your password.

Which services are supported?

See the Services catalog. Coverage grows as plugins are added — and you can write your own (see Write a plugin).

Can I track two accounts of the same service?

Yes, with profiles. Each profile is a fully separate, isolated context, switched from the top bar — connect your work account in one profile and your personal account in another. Within a single profile it's one account per service, so you switch between them rather than seeing both side by side.

Is it free?

Yes — Butin is free and open source. The desktop application is licensed under Apache-2.0, while the SDK and plugins are MIT-licensed (see Licensing). If it saves you time, a ⭐ on the GitHub repo is appreciated.

What platforms does it run on?

macOS, Windows, and Linux (it's an Electron desktop app).
