Supported platforms
crossfriend helps you find people you already know on one platform across the other platforms they've explicitly opted in to be found on. Here's every platform we support today and how each one can be used. It's consent-first and OAuth-only — we never ask for your password.

- We can read your own friend/follow list here, to find who you know elsewhere.
- Target
- You can opt in to being discovered here when a friend looks you up.
- Sign in
- Connect this platform directly, with its own official sign-in.
- via Discord

7 of these can be a source today; the rest are discovery targets we'll promote to sources as their friend graphs become readable. A target-only platform is still useful — opt in and a friend who knows you elsewhere can find you there.
