Push notifications to phones and desktops
About this program
Backup results, certificate renewals and monitoring alerts reach the responsible person's phone in seconds — over your own server, not a third-party push service.
Features
- Publish via simple HTTP PUT from any script
- Android and iOS apps, plus desktop notifications
- Topics with access control and priorities
- Alert content stays on own infrastructure
Why we chose it
Because an alert nobody sees is the same as no alert, and because a self-hosted push channel costs one container and removes a dependency.
