crossfriend

Find the people you already know on one platform across the other platforms they have explicitly chosen to be found on — without ever handing over a password or uploading a contact list. Privacy and consent are the entire point: you are only ever shown someone once they have opted in to be discoverable, and you control exactly who can find you.

Why crossfriend

Consent is the product

Nobody appears to you until they have explicitly opted in. No scraping, no guessing, no “people you may know” built from data you never shared.

We never see your password

You sign in through each platform’s official login; crossfriend only ever receives the identity you choose to share.

Nothing stored about the rest

Your friend list is read live to find who opted in, then discarded — the people who aren’t matches are never recorded.

How it works

Sign in with a platform you already use — through that platform’s own official login page. crossfriend never sees, asks for, or stores your password.
Choose who can find you, and where. Nothing about you is shared until you create a permission, and you can revoke any of it at any time.
Discover the friends who opted in and connect with them there.

See every supported platform and how each can be used, or read the FAQ for how discovery, consent, and your data work.

We never ask for your password. Each option below sends you to that platform’s official sign-in (OAuth) on the platform’s own site; crossfriend only receives the identity you choose to share. See our privacy policy and terms of service.
