Best Self Hosted Alternatives to Sinch SMS API

ntfy (pronounced “notify”) is a simple HTTP-based publish/subscribe notification service. It lets apps, servers, and scripts send push notifications to phones, desktops, and web browsers using straightforward HTTP requests.

Key Features

• Publish messages to topics via HTTP PUT/POST
• Topics are created dynamically by publishing or subscribing
• Web app for browser subscriptions with desktop notifications
• Push delivery to mobile clients (Android and iOS apps are available)
• Works well for automation and server-to-user alerts without complex integrations

Use Cases

• Send server and backup job notifications from shell scripts or cron jobs
• Application alerting (deployments, monitoring events, CI results) via a simple REST-style interface
• Personal notification hub for homelab events and device automation

Limitations and Considerations

• If used without accounts/reserved topics, topic names function like shared secrets and should be hard to guess

ntfy is a pragmatic choice when you want a minimal, reliable notification pipeline based on plain HTTP. It is well-suited for automation scenarios and for teams or individuals who prefer a simple pub-sub model over heavy messaging platforms.
