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

Provides generated Python protobuf code for the OpenTelemetry data model, enabling serialization and deserialization of telemetry data in OTLP format.

Low friction install with a single runtime dependency (protobuf). Actively maintained with a recent release (28 days ago) and continuous repository activity.

Apache-2.0 permissive license allows commercial and private use with minimal restrictions, suitable for most integration scenarios.

Usage

pip install opentelemetry-proto

from opentelemetry.proto.trace.v1 import trace_pb2

span = trace_pb2.Span()

Requires Python 3.10 or later; protobuf must be installed as a runtime dependency.

Verdict: Production-ready proto library with active maintenance, no known vulnerabilities, and a permissive Apache-2.0 license. Minimal install friction and broad Python version support (3.10–3.14) make it a reliable choice for OpenTelemetry integration.

Needs verification
