Testgram is an open source messaging platform. You can read the source, host the server yourself, or build your own client on top of it. Here are the apps we publish.
Testgram is open source. The server and the clients we build are published on GitHub, so you can read the implementation, audit it, and build it yourself. The apps listed further down are the upstream projects our code is derived from; they are maintained by their own authors.
