I’ve been working on Telemetry Tracker over the past several months. It started as a side project because I wanted a simple telemetry platform that I could both self-host and use as a hosted service.
Today it includes error tracking, custom events, session monitoring, organizations, projects, API keys, and SDKs for React, Next.js, Vue, Nuxt, React Native, Node.js and NestJS.
The whole project is open source (MIT) and written in TypeScript.
There’s still a lot I’d like to build—performance monitoring, alerting, source maps, session replay—but I felt it was time to share it instead of waiting for it to be “finished.”
I’d love to hear what you think. Happy to answer any questions about the architecture, implementation, or why I made certain design decisions.
