This is a free public Syncplay server by dnomd343 that supports TLS encryption and room isolation. In the Asia-Pacific region, especially China, it has lower latency and can be used as an alternative to the official server.
You and your friends only need to fill `syncplay.343.re` in the server address option and click `Run Syncplay`, if you encounter any problems, please send email to `i@343.re`.
PS: this project is based on https://github.com/dnomd343/syncplay-docker, you can also build your own server.
