IPPin – Public IP Change Alerts

Monitor your home public IP and auto-update allowlists when it changes.

Problem

Developers doing local debugging, maintaining server allowlists, or self-hosting at home get their public IP changed by the ISP without warning. Checking it manually every time is a constant interruption, and fixed IPs are not commonly offered.

Solution

A tiny agent or container that probes your public IP on a schedule, pushes a notification via email, Telegram, webhooks, or Apprise-compatible channels when it changes, and exposes a small API/template to update DDNS records or firewall allowlists automatically.

Users

Remote developers, self-hosters, small teams needing reliable access to home servers or NAS devices.

MVP

Lightweight client/container that probes public IP on interval; multi-channel alert on change; IP history timeline; one-tap copy of current IP; webhook to update DDNS or firewall rules.

Revenue

Open-source core with a hosted subscription for multi-node history and webhook management; optionally a one-time purchase companion desktop/mobile app.

Why now

Self-hosting and work-from-home are mainstream, yet fixed IPs remain rare. This is a weekend-to-two-week build with a clear, recurring user need.
