Snapcast is a Snapcast control client and player for Android. It uses the Snapcast JSON-RPC API to control your synchronous multi-room audio player. This App is not meant for productive use and will only run when you have a Snapserver installed in your local network. Snapcast is a multi-room client-server audio player, where all clients are time synchronized with the server to play perfectly synced audio. It’s not a standalone player, but an extension that turns your existing audio player into a Sonos-like multi-room solution. The server’s audio input is a named pipe /tmp/snapfifo. All data that is fed into this file will be send to the connected clients. One of the most generic ways to use Snapcast is in conjunction with the music player daemon (MPD) or Mopidy, which can be configured to use a named pipe as audio output.

Snikket is a personal messaging app designed for groups such as family, friends, clubs or small organizations. It can be used to text and call with contacts without handing over your data to large corporations. This works because, instead of a centralized server, each group has their own private Snikket server under their control. To get started you can choose: - Self-host your own Snikket instance using the open-source Snikket server software on any Linux server, - Use the simple hosting service provided by the Snikket not-for-profit organization, - Or join an existing instance of someone you know (they can send you an invitation). Guides are available at the snikket.org website. ℹ️ Important note: Unlike many other messaging apps, there is no centralized Snikket service. The app requires a Snikket instance or invitation to get started. Both the app and the server are 100% free and open source software. The Snikket Android app is based on the excellent Conversations project by Daniel Gultsch.
