WebRtc server for making a video conference app in flutter that scales well

Question

I am trying to make a video conference call app in Flutter app with web support. I don't want to use videoSDK like Agora.

I found some open-source SFU servers such as Livekit, Jitsi and mediasoup. I am not sure which one to use. I want to know which of them or any other SFU serves that provides good developer experience and has easier learning curve. Thanks.

All of the servers that you describe are high-quality SFUs, and you will probably be happy whichever you choose. There are some differences, though:

• Jitsi is great, but it's a little bit too complex for many needs, and requires a fair amount of infrastructure (JRE, XMPP); I don't recommend it if you want to develop your own client;
• Livekit is a commercial fork of ion-sfu; its main advantage is the large number of client libraries available (browser, Android, iOS); it has some minor technical issues (like poor audio-video synchronisation), but should work well for most applications;
• Mediasoup has good reputation, but I haven't looked at it myself. It provides a client library.

There are some other well-done servers:

• Janus is a fast and lightweight SFU written in C++ with no dependencies; it ships with a JS client library, and is extremely flexible due to its plugin system;
• Galene is a fast and lightweight SFU written in Go; the protocol is well documented, and there is a client library (disclaimer, I'm the main author).
