|pypi|

.. |pypi| image:: https://badge.fury.io/py/opentelemetry-instrumentation-fastapi.svg :target: https://pypi.org/project/opentelemetry-instrumentation-fastapi/

This library provides automatic and manual instrumentation of FastAPI web frameworks, instrumenting http requests served by applications utilizing the framework.

auto-instrumentation using the opentelemetry-instrumentation package is also supported.

Installation

pip install opentelemetry-instrumentation-fastapi

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Automatically instruments FastAPI applications to emit OpenTelemetry traces for HTTP requests, enabling observability of web request handling and performance.

Low install friction with a pure-wheel distribution and five straightforward OpenTelemetry dependencies. Actively maintained with a release 28 days ago and recent commits; Beta status indicates ongoing development.

Apache-2.0 permissive license allows use in commercial and proprietary projects with minimal restrictions, requiring only license and copyright notice retention.

Usage

pip install opentelemetry-instrumentation-fastapi

from opentelemetry.instrumentation.fastapi import FastAPIInstrumentor

FastAPIInstrumentor.instrument_app(app)

Requires Python >=3.10; OpenTelemetry SDK and exporter must be configured separately to emit traces.

Verdict: A well-maintained, low-friction instrumentation library for FastAPI observability. Active development, permissive licensing, and zero known vulnerabilities make it suitable for production tracing pipelines, though Beta status warrants monitoring for API changes.
