wire-server

Wire was able to implement a fully E2E-encrypted messenger with proper multi-device support almost a decade ago, long before it became mainstream. Fully FOSS too, including the server. For some reason it never became popular. They don't have proper desktop clients (just the usual Electron mess), but then, which one of them does except for Telegram? https://github.com/wireapp/wire-server , etc.

Also the server backend for the Wire messenger https://github.com/wireapp/wire-server

Server is AGPL: https://github.com/wireapp/wire-server/blob/develop/LICENSE and clients are GPL it seems.

> See also Wire who had serious crypto and promises to open source everything, but to my knowledge the server side was never released The wire server code is open source AFAIK [0] > This repository contains the source code for the Wire server. It contains all libraries and services necessary to run Wire. [0] https://github.com/wireapp/wire-server

It isn't open source in the sense that it's in Haskell, meaning it's encrypted :-) Otherwise it's totally open source: https://github.com/wireapp/wire-server

I use Wire, have only two contacts which also using Wire. I like that they have published the server source code https://github.com/wireapp/wire-server

One that I use all the time is shellcheck, and git-annex. Others in the mainly-used-by-programmers-category include xmonad and hledger. https://github.com/owickstrom has some GUI Haskell apps. Facebook's Sigma and https://github.com/wireapp/wire-server may be the ones with the most non-programmer users? http://postgrest.org/ and https://hasura.io/ seem interesting. https://www.quora.com/What-is-the-largest-commercial-program... says the largest Haskell code-base is probably Standard Chartered trading system. more at https://github.com/topics/haskell and https://serokell.io/blog/top-software-written-in-haskell

As a professional Haskell programmer for a bit now, I see no problem with a chat app in Haskell. In fact, something close is wire[0] whose server source code is here[1]. They are a secure alternative to slack and mattermost for the curious. 0: https://wire.com/en/explore/competitive-advantage/ (this gave the best explanation in the comparison section of what it actually is imo) 1: https://github.com/wireapp/wire-server

Since nobody's mentioned Wire, it's not a 1:1 alternative but it's close in terms of chat. I don't think any 1:1 alternative to KeyBase will rise up anytime soon, hosting git and files will be a bit to build up to. Website: https://wire.com/en/ Their backend is open source unlike KeyBase: https://github.com/wireapp/wire-server

Wire works on every platform (you don't need a cellphone to sign up, only e-mail), and they released their server code a while ago as well, and documentations on how to set it up is work in progress, which means that in the future (actually even now, but most people don't know how to set it up :P) you won't even have to rely on their servers, you can easily self-host one. https://wire.com/en/download/ https://github.com/wireapp/wire-desktop https://github.com/wireapp/wire-server https://wire.com/en/security/

Wire[1], another E2EE chat application (using libsignal, just like WhatsApp and Signal itself), does not require this. It also has open-sourced its client and server applications[2], and is in the process of documenting how to run them yourself. It also has a pretty solid API[3]. One downside for JS haters, though, is that while the application isn't a wrapper for the site it is still Electron. 1. https://wire.com/en/security/ 2. https://github.com/wireapp/wire-server 3. https://developer.wire.com

That seems really exciting. When that occurs I will most likely switch over. Unfortunately you can't quite host it your self yet: https://github.com/wireapp/wire-server/issues/2

And a little bit of Rust, too! https://github.com/wireapp/wire-server/tree/master/libs/libz...
