FAQ

How do I get the node content to paste?

Run this command in your terminal: curl -s "YOUR_SUBSCRIPTION_URL" | base64 -d — this downloads and decodes your subscription content locally. Then paste the output here. Never paste your subscription URL into online converter websites.

Is my data safe?

Yes. All parsing and config generation happens entirely in your browser using JavaScript. No data is sent to any server. You can verify this by checking the network tab in your browser's developer tools.

Which protocols are supported?

Currently supported: VMess, VLESS, Trojan, and Shadowsocks (SS). These cover the vast majority of proxy subscription nodes. Transport types including WebSocket, gRPC, HTTP/2, and HTTPUpgrade are also supported.
