Those all look really cool!
I’m making one
It’s called Metamorphic and uses Elixir, OTP, and Phoenix.
It currently isn’t open source but I do plan to open source it under our company’s repository, Core Theory, when it’s closer to production ready.
It’ll be at metamorphic.app (currently nothing there), and I’m planning to do an invite stage before releasing to the public.
It is going to function a little bit differently from typical (major) social networks, (1) in that it’s a paid service, (2) you own 100% of your data, (3) it’s much more aligned with connecting and sharing with people you know rather than people you don’t know, and (4) it’s designed to be a tool for you to use rather than a tool to mine and use you.
I have a lot of hopes for it and inspirations behind deciding to try to make something like this… you can follow along with me at our company podcast if you’d like .
Also, on our Patreon I’ve released some early marketing images that give a preview of some the features in development.
Also, if anyone knows how to implement, or is thinking of implementing, the IETF’s upcoming Messaging Layer Security standard protocol, then please send me a message as I am excitedly following its development for hopeful use in Metamorphic.
