Cordon

How it works

Normally every request goes straight to the internet. Cordon lets you decide, per request, where it goes.

Rules send each request through your server or straight out, or block it.

1
Add a server
Paste a share link, scan a QR code or add a subscription. Cordon checks that it can run the server before saving it.
2
Set your rules
Choose what goes through your server, what stays direct and what is blocked. Think of mail filters, but for network traffic.
3
Connect
Tap the ring. Cordon shows the state in words and colour, and explains plainly if something fails.
4
Watch and refine
The Data view lists every connection with the rule that matched. Turn any entry into a rule with one tap.

What Cordon does not do

We don’t sell, run or recommend servers. You bring your own endpoints.

There is nothing to sign up for. Your servers, rules and logs stay on your device.
