💡 About

PushBits is a relay server for push notifications. It enables you to send notifications via a simple web API, and delivers them to you through Matrix. This is similar to what Pushover and Gotify offer, but it does not require an additional app.

The vision is to have compatibility with Gotify on the sending side, while on the receiving side an established service is used. This has the advantages that we need to maintain neither plugins (like those for Watchtower and Jellyfin) nor clients.

🤘 Features

• [x] Multiple users and multiple channels (applications) per user
• [x] Compatibility with Gotify's API for sending messages
• [x] API and CLI for managing users and applications
• [x] Optional check for weak passwords using HIBP
• [x] Argon2 as KDF for password storage
• [ ] Two-factor authentication, issue
• [ ] Bi-directional key verification, issue

❓ Frequently Asked Questions (FAQ)

Why Matrix instead of X?

This project totally would've used Signal if it would offer a proper API. Sadly, neither Signal nor WhatsApp come with an API (at the time of writing) through which PushBits could interact.

In Telegram there is an API to run bots, but these are limited in that they cannot create chats by themselves. If you insist on going with Telegram, have a look at webhook2telegram.

The idea of a federated, synchronized but yet end-to-end encrypted protocol is awesome, but its clients simply aren't really there yet. Still, if you haven't tried it yet, we'd encourage you to check it out.
