Observability micro framework.

Our review

What we like

Add metrics to existing code with simple annotations or macros. Supports Rust, Go, Python, TypeScript, C#. Alerts and SLOs defined in code next to each instructed method. VS Code extension provides deep links to generated graphs. Can run locally, but designed to export to Prometheus.

What we don't like

Requires Prometheus for metrics, although it is based on top of OpenTelemetry.
