Note: This open source software has been marked as clean by Jotti (.exe, .zip, .dmg, legacy .dmg) and VirusTotal (.exe, .zip, .dmg, legacy .dmg). Syncplay might be flagged as suspicious by some anti-malware systems simply because it is niche software downloaded from the Internet but as we are open source anyone can audit our code if they wish to do so.

Advice: If you use public servers, avoid ports 8995 and 8999

You can use any public server so long as you are all on the same one. However, the majority of people currently use ports 8995 and 8999 which means that for a more stable connection you should probably go for ports 8996, 8997 or 8998. On the sidebar to the right you will see a highlighted server selected at random from the lesser-used servers.
