Currently there is a high demand for online conference tools, but a low supply of tools that don’t spy on you.
What I want:
- free server (no GAFAM or Cloudflare), free software, no tracking
- voice conference - video not necessary
- presentation sharing would be nice, but not necessary
- should work flawlessly
- either free or cheap, but you should be able to test it for free first
Do you have any positive experience with Jitsi, Mumble, Jami or whatever?
