Autometrics

Autometrics is an open source observability framework that helps developers monitor their applications. It provides decorators and wrappers that automatically instrument functions in your code, tracking key metrics like error rates, request rates, and latency without requiring manual configuration. The framework works with multiple programming languages including Rust, TypeScript, Python, and Go, making it accessible across different tech stacks.

What sets Autometrics apart is its focus on developer experience. It generates powerful Prometheus queries automatically, provides a command-line interface for local testing, and integrates with Slack to deliver actionable alerts complete with charts. The framework builds on Prometheus and OpenTelemetry standards, ensuring compatibility with existing observability ecosystems. Developers can define Service Level Objectives directly in their source code, making alert configuration part of the development process rather than an afterthought.

This tool is particularly valuable for development teams building and maintaining backend services who need to quickly identify and resolve production issues. It helps engineers track performance across deployments, spot problematic commits, and maintain visibility into system health without extensive manual instrumentation work. The open source nature means teams can deploy it to their own infrastructure while benefiting from continuous community improvements.
