ASGI instrumentation for OpenTelemetry
Decision gist · record as of 2026-08-14
Yes, if you are building or operating ASGI applications and need distributed tracing or request instrumentation. The package is actively maintained, has no security issues, and integrates cleanly into the OpenTelemetry ecosystem. The beta status is typical for instrumentation libraries and should not deter adoption in production when paired with a stable OpenTelemetry exporter.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; your ASGI application must already be instantiated before wrapping with the middleware.
- Low friction install with 5 runtime dependencies, all within the OpenTelemetry ecosystem.
- Actively maintained with recent release and no known vulnerabilities.

What it is and what it does
This package adds OpenTelemetry tracing to any ASGI-based web framework by wrapping your application with middleware that automatically captures request timing and generates spans for distributed tracing. It integrates with the OpenTelemetry ecosystem—relying on opentelemetry-api, opentelemetry-instrumentation, opentelemetry-semantic-conventions, and opentelemetry-util-http—to emit standardized trace data that can be exported to observability backends.
The middleware is designed to work transparently with frameworks like Django, Starlette, FastAPI, and Quart without requiring changes to your application logic. It's currently in beta status but actively maintained, with support for Python 3.10 through 3.14. The package has no known security vulnerabilities and is permissively licensed under Apache-2.0.
Use it for
- Instrument FastAPI or Starlette applications to emit traces for request latency analysis and debugging
- Add distributed tracing to Django ASGI deployments for end-to-end request flow visibility
- Collect request timing metrics across microservices using OpenTelemetry exporters
- Generate spans for monitoring and alerting on slow or failing ASGI requests
- Integrate with observability platforms via OpenTelemetry collectors
