ntfy review 2026: open-source push notifications via simple PUT/POST requests. Self-host free or use the hosted service. See features, pricing and alternatives.
ntfy is an open-source, HTTP-based pub-sub notification service created by developer Philipp Heckel that grew from a personal project into a widely used tool in the self-hosting and developer communities. It lets anyone send a push notification to a phone, desktop or terminal with a simple PUT or POST request, without needing an account, API key or app registration.
Because ntfy is fully open source under Apache 2.0 and GPLv2, it can be self-hosted for complete control and zero cost, or used via the free public server at ntfy.sh. The project has attracted a large open-source community, with more than 30,000 GitHub stars and 300-plus contributors.
Topics in ntfy are created on the fly simply by publishing or subscribing to a topic name, and messages support rich formatting including priorities, action buttons, tags, emoji shortcuts and file attachments. Native apps are available for iOS, Android and desktop, alongside a web app and simple curl-based publishing.
ntfy integrates with a wide range of DevOps and self-hosted tools, including GitHub Actions, Home Assistant, Uptime Kuma, Sonarr and Radarr, making it a popular choice for build alerts, monitoring notifications and home-automation triggers.
ntfy is free to use in two ways: self-hosting the open-source server on your own infrastructure at no cost, or using the public ntfy.sh server without signing up (topics act as a shared secret and are only semi-private).
For users who want private reserved topics, higher message limits and larger attachments without running their own server, ntfy.sh offers paid hosted tiers: Supporter (around $5-6/month), Pro (around $10-12/month) and Business (around $20-25/month), with larger custom deployments available on request.
