On this page you can find Telegram apps for every platform and links to their open source code.
For the moment we are focusing on open sourcing the things that allow developers to quickly build something using our API. We have published the code for our Android, iOS, web and desktop apps (Win, macOS and Linux) as well as the Telegram Database Library.
This code allows security researchers to fully evaluate our end-to-end encryption implementation.
