OpenTelemetry (OTel) is an open-source observability framework maintained by the Cloud Native Computing Foundation (CNCF). It provides a single, standardised set of APIs, SDKs, and instrumentation libraries for collecting traces, metrics, and logs from your services.

​
Why OpenTelemetry?

Before OpenTelemetry, every observability vendor had its own proprietary agent or SDK. Switching tools meant re-instrumenting your entire codebase. OpenTelemetry solves this by providing a vendor-neutral standard that any platform — including Trace0 — can receive data from.

Open standard

OpenTelemetry is governed by the CNCF and supported by every major cloud provider and observability vendor. Your instrumentation is never locked to a single tool.

Rich ecosystem

Libraries exist for every major language and framework. Most popular frameworks (Spring Boot, Express, Django, FastAPI, and more) are auto-instrumented with zero code changes.

Traces, metrics & logs

A single SDK captures all three telemetry signals — no need for separate agents or integrations for each signal type.

Future-proof

Because your code uses open-source instrumentation rather than proprietary agents, you can switch observability backends at any time without touching your application code.
