What is Butin
A local-first desktop app that puts all your accounts in one place — readable offline, on your own machine.
Butin is a local-first desktop app that puts all your accounts in one place. It pulls the billing, usage, members, and documents from every service you use into a single local dashboard — readable without logging in, using the session you already logged in with, and kept on your machine.
It reaches the data services keep behind their own dashboards (no API needed), downloads every document, and keeps the history they don't. No credentials handed to anyone. Nothing uploaded anywhere.
The model — in three steps
- Sign in. You log into a service by hand in a normal window (password, MFA, SSO — all fine). Butin captures that session and stores it, encrypted, on your computer. It stays valid only as long as the service keeps it alive — anywhere from ~20 minutes to a few days.
- Fetch headless. While the session holds, Butin reads the data quietly in the background — with no browser window left open. When the session expires, you sign in again to pull fresh data.
- Keep your data. Each fetch becomes a clean dashboard — spend, usage, members, documents — saved only on your disk, with history. The data you've already pulled stays yours even after the session is gone.
The promise underneath all of it: it runs in your own session, locally, with no server custody of your credentials. The account it reads is always your own.
Where to next
- Getting started — install and connect your first service.
- How it works — the engine, and why it's private by design.
- Write a plugin — add a service of your own.
