Blipr turns any topic into an instant push notification. Create a topic in the app and get alerted the moment a message is published to it - from your servers, scripts, CI, cron jobs, or a one-line curl. Priority 5 alerts are Time-Sensitive: they break through Focus and Do Not Disturb, so the one that matters always reaches you. - Instant delivery over a live connection - watch messages arrive in real time - One Feed for every topic - search, filter by topic, unread or priority, and reply from the list - Priority levels 1-5, with Time-Sensitive delivery at the top level - Publish from anywhere: curl -d "hello" https://blipr.dev/blip/your-topic - Reply from a notification - tap Yes/No or Acknowledge without opening the app - Self-hostable: use blipr.dev or point Blipr at your own server - Share a topic with a QR code or link - Sign in with Apple to create topics, and keep them in sync across your devices - Light & dark, Dynamic Type, built for iOS Blipr is a client for an ntfy-style notify service. Creating a topic takes a free account; publishing to one and subscribing to it do not. Topics are public by name - use a long, unguessable name for anything sensitive.
