It's not really clear to me what livekit is, but it appears to be some sort of agentic coding tool.

Perhaps the similarity to Jitsi Meet is due to it regurgitating the source that an AI has ingested.

The code base looks very different but a lot of the same terminology is used and the UI layout, navigation, menu options etc look very similar.

Nah, it's just a basic case of a pivot from a company that previously offered a great open source (MIT licensed) product written in Go that offer WebRTC-based backbone to build audio and video sharing products upon: https://github.com/livekit/livekit

The AI stuff that the original LiveKit company put on top of it (to pivot to more investor-friendly endeavours) is not that relevant in this case, in my humble opinion.

Ah that's it. I made the mistake of visiting their website which is heavy on marketing and low on what the heck their product actually is.

Makes more sense reading the Github (though that too is pushing the AI angle more than A/V stuff.
