ntfy (pronounce: notify) is a simple HTTP-based pub-sub notification service. It allows you to send notifications to your phone or desktop via scripts from any computer, entirely without signup or cost. It's also open source (as you can plainly see) if you want to run your own.

I run a free version of it at ntfy.sh. There's also an open source Android app (see Google Play or F-Droid), and an open source iOS app (see App Store).

There are a few ways to get in touch with me and/or the rest of the community. Feel free to use any of these methods. Whatever works best for you:

• Discord server - direct chat with the community
• Matrix room #ntfy (+ Matrix space) - same chat, bridged from Discord
• Reddit r/ntfy - asynchronous forum (new as of October 2022)
• GitHub issues - questions, features, bugs
• Email - reach me directly (I usually prefer the other methods)

For announcements of new releases and cutting-edge beta versions, please subscribe to the ntfy.sh/announcements topic. If you'd like to test the iOS app, join TestFlight. For Android betas, join Discord/Matrix (I'll eventually make a testing channel in Google Play).

I welcome any and all contributions. Just create a PR or an issue. For larger features/ideas, please reach out on Discord/Matrix first to see if I'd accept them. To contribute code, check out the build instructions for the server and the Android app. Or, if you'd like to help translate 🇩🇪 🇺🇸 🇧🇬, you can start immediately in Hosted Weblate.

I have just very recently started accepting donations via GitHub Sponsors, and Liberapay. I would be humbled if you helped me carry the server and developer account costs. Even small donations are very much appreciated. A big fat Thank You to the folks already sponsoring ntfy:

I'd also like to thank JetBrains for providing their awesome IntelliJ IDEA to me for free, and DigitalOcean (referral link) for supporting the project:
