Build your own Krotze client

Everything the official app does, this API does — registering an identity, joining channels, sending messages and files, and receiving Web Push while your client is closed. There is no login and no bearer token: each device holds a secret and signs every request with it.

About “Try it out”: it works for the unsigned endpoints (/api/push/key, GET /api/join/{token}, POST /api/session). The signed ones need an HMAC computed over the method, path, timestamp, nonce and body, which a browser form cannot produce — use the reference client in docs/API.md instead.
