Managing alerts across modern applications can quickly get complex—or expensive. Whether you're a solo dev, a small team, or running microservices across environments, you need a tool that just works without locking you into a platform or draining your budget.
That’s why I built N1netails – a developer-first, open-source alerting platform.
🧠 What is N1netails?
N1netails is a self-hosted alerting system designed for developers who want more control and less complexity. Inspired by the simplicity of SLF4J for logging, N1netails lets you send and manage alerts with pluggable integrations and full extensibility.
✅ Built in Java
✅ Send alerts via simple HTTP POST
✅ Works with your existing stack (Spring Boot, Angular, Node, Bash, etc.)
✅ Integrates via n1netails-kuda (Java library) or REST API
✅ Self-hosted and open-source — no vendor lock-in
✅ Lightweight enough to embed in microservices
✅ Supports real-time notification channels like Discord and Telegram
🔧 How It Works
You deploy the N1netails API and N1netails UI and send alerts from your app using the Kuda SDK (or directly via HTTP):
📦 Example: Docker quickstart
If you want to try N1netails out without hosting it yourself you can send posts request to the N1netails Dashboad
Alerts appear on the N1netails dashboard.Here is how to make a post request to N1netails
N1netails Kuda Java SDK
If you are building your services using Java you can use the kuda library to easily send alerts from your app to the N1netails project
