About NotifyWhenEvent
A personal API monitoring tool that grew into something bigger
The Beginning
NotifyWhenEvent started as a personal project. Like many developers, I needed a reliable way to monitor API responses and webhook payloads for meaningful data changes—then notify or call another API without maintaining another polling script. Existing solutions were either too complex, too expensive, or did not fit that workflow.
Built for Personal Use
I created this tool to solve my own problems: polling API endpoints, processing JSON, keeping state between runs, and getting Telegram alerts when something important changed.
The Evolution
As I used the tool more and more, I realized it could be valuable to users in various fields.
Whether you're a business owner, a researcher, or just someone who wants to stay updated on important changes, this tool could be interesting and useful.
From Personal to Shared
What started as a personal utility has grown into something that could help other developers and teams. The core philosophy remains the same: keep it simple, make it reliable, and focus on what actually matters.
The Mission
NotifyWhenEvent is now available as a free beta, allowing users in various fields to benefit from the same monitoring capabilities I built for myself.
It's not about creating another complex enterprise solution — it's about sharing a simple, effective tool.
Simple, Effective, Shared
The goal is simple: provide a straightforward way to monitor API and JSON responses, process them in visual workflows, and trigger actions—without the complexity and cost of enterprise observability platforms.
What We Believe In
Simplicity
Complex tools solve complex problems. Simple tools solve real problems.
Reliability
When you need to know about changes, you need to know for sure.
Accessibility
Technology should be accessible to everyone, not just technical experts.
