ntfy is a simple service that sends push notifications to your phone or desktop when a script or program makes a web request. It is for people who want to get alerts from their own tools without signing up or paying, and it can also be self-hosted.

Before you build

Planning something for push notifications? See what exists first, so you can reuse parts or explain what's different. Paste this into any AI assistant:

Read the list of open-source alternatives at https://opensourceeverything.org/data/groups/push-notifications.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:

Fix the list itself

A project or closed app missing from this list, or a mistake on it? These open a short form on GitHub, and a mod reviews it. To say what a project can't do, use What's missing.

About this page

Replaces fully means it does the main job of these apps; Replaces partly means it covers some of it.

Licenses: every project here uses an open-source license (what each one means). Open core means some parts are paid or under another license.

GitHub stars are shown for reference. They measure popularity, not whether it replaces anything.

Verified means r/TrueOpenSource mods checked it: open-source license, maintained, and it really does the job.
