Connect your tools without logging in again
Excellent Self-Integration reads an API key off a dashboard you're already signed into and hands it to your own local Excellent app. No copy-pasting keys, no separate logins — and your keys never leave your machine.
Requires the Excellent app running locally · Chrome 116+
Three clicks, no credentials in your clipboard
The extension runs in your real browser, on your real sessions — so there's nothing to re-authenticate.
Click Connect in Excellent
Inside your local Excellent app, hit “Connect” for a tool like Stripe or Supabase. The app asks the extension to fetch the key.
It reads the key, already signed in
The extension opens that provider’s settings page in your real browser — where you’re already logged in — reveals the API key, and reads it. No new login, no copy-paste.
The key goes to your machine only
It hands the key straight to your local Excellent app over loopback, which seals it. The key never touches Excellent’s servers or anyone else’s.
Built so a credential physically can't reach us
This is the same posture as the rest of Excellent: local-first, separation of duties, nothing phones home.
Local-first by construction
The extension talks only to your local Excellent app (localhost). It refuses any non-loopback target — there is no cloud endpoint to leak to.
Acts only when you ask
It does nothing on its own. Every capture is a job you started by clicking Connect, authenticated with a one-time pairing token you generate in the app.
Keys are never stored
The extension keeps only the pairing token and your app URL. API keys are read on demand, delivered, and never persisted by the extension.
The full data practices are in the extension privacy policy. Works today with Stripe, Supabase, PostHog, Plausible, Greenhouse, and Ashby.
