Zyrdon Notify and Zyrdon Relay
Two hosted services for your Zyrdon server. Connect the server to a Zyrdon account once, from Admin, and both turn on. Both are free.
Zyrdon Notify
Lock-screen notifications in the official app.
Your server sends each notification to Zyrdon Notify, which delivers it through Apple's push service with the official app's key. Without Notify, push needs an app you build and sign yourself, with your own key.
Zyrdon Relay
Reach your server from anywhere, with no open port.
Your server keeps one outbound connection to the relay. The app tries your server's address first and goes through the relay when it can't reach it. The app's encrypted connection to your server runs end to end, so the relay carries bytes it can't read.
Fair use: 50 GB through the relay per server each month. Past that, the relay pauses for that server until the month ends, and Notify keeps working.
Free, with a promise on price
Notify and Relay are free with a Zyrdon account. There is no trial.
Before any price change, you get 30 days' notice by email. Each server keeps working until you pick a plan or the notice period ends.
Connect a server
- In Admin, open Settings and choose Connect to Zyrdon.
- Open the link Admin shows, or scan its QR code, and sign in with Apple or GitHub.
- Connect it as a new server, or have it replace a server you connected before. A replacement keeps the relay address, so enrolled apps keep working.
Each server gets its own credential. Revoke one from your account without touching the others.
What the relay sees
Encrypted bytes, plus IP addresses, connection times, and byte counts. The app and the server encrypt your chats end to end. Their code goes public on GitHub later, so you can audit the app and the server then.
Running it all yourself
Push works without Notify when you sign the app yourself and use your own Apple push key. For remote access without Relay, use your own tunnel or VPN, or publish the app port.
The push and remote access guides go public on GitHub later, with the source code.
