I've installed my own instance of Jitsi and it's particularly useful for video chats with older people or those less technically able.

My use case is elderly in-laws who can use a laptop, but are incapable of installing anything other than malware. Installing Zoom would be too complicated for them and would probably discourage them from participating in a family video chat.

With Jitsi, I send them a link by email and text them to check their email. They click on the link, browser opens and voila! - they're able to chat with their family, with zero fuss.

Costs me €2.49 per month for a Hetzner cloud instance.

Hi, this is really interesting for me. Could you share a bit more details of your setup?

I am also doing this, so I'll take the liberty of answering. There's a turnkey docker which should take a few minutes to install:

https://github.com/jitsi/docker-jitsi-meet

Put nginx in front of it with Let's Encrypt and it shouldn't take more than half an hour to set up. After that you basically get a clone of meet.jit.si.

I'm using it with the low level JS library in order to build a product that contains video chat. There was a bit more messing about for me, but only a bit.
