Show HN: Alerio – Turn Webhooks into Critical VoIP Calls (Overrides Silent Mode)

Hi HN, I’m the developer of Alerio.

I built this because I manage a few production servers. Recently, my main API became unresponsive at 3 AM. I had uptime monitoring set up (Grafana/Uptime Kuma), but the standard push notification was too short/quiet to wake me up, especially since my phone was on "Do Not Disturb".

Existing solutions like PagerDuty felt like overkill (and too expensive) for my personal projects.

So I built a native Android app that acts as a dedicated pager. It listens for incoming Webhooks and triggers a full-screen VoIP call using Android's ConnectionService API. This allows it to: 1. Bypass Silent Mode and DND restrictions legally. 2. Ring continuously until I wake up and acknowledge the incident. 3. Multi-device support (added in v1.1)

Tech Stack: - Backend: Go (Fiber) + PostgreSQL - Mobile: Kotlin (Native) - Realtime: WebSocket + FCM

It has a free tier for hobbyists. I'd love to hear your feedback on the reliability and the approach.

Happy to answer any technical questions!
