I was on the beta testing team and have been using Beeper for a little over two years now.
The convenience of having an application to house all of your chat networks is amazing.
My worry would be who is funding it and how they plan to keep operating. Venture Capital startups will always betray their users.
their clients are proprietary but it’s built on matrix (federated chat kinda like xmpp) and their bridges (things that connect matrix to other protocols) are open source
they say you can use any matrix client, and that you can host your own home server with their bridges
I have my own matrix server that I primarily use like beeper and bridge all my chats together. Even using some of their bridges, it’s been pretty reliable for years.
I know that a few people are hating on the closed source client, but that feels unfair to me. They provide lots of open code in the form of bridges which is really the meat of the offering. Their client just makes using the bridges easier for the lay person. The bridges are super easy to use without it, invite the bridge bot to a chat room, type login and do what it says, then type login-matrix and your pretty much done.
The I suspect that the same people who are displeased about the closed client also like using tailscale which is generally pretty popular but has closed source clients on Windows and Mac as well as the server (though all support the open source headscale server)
They will be offering a premium subscription offer for more bells and whistles other than the free option…I don’t know anything about user betrayals conducted by Beeper.
