# sentry-protos — Generated python code for sentry-protos

License: unclear · Maintenance: active · Downloads: 366.0K/mo

## What it is and what it does

Sentry-protos is a schema registry and code-generation tool for protocol buffers and gRPC definitions used in cross-process communication. It holds canonical proto files organized by service domain and version, with tooling to generate Python and Rust client bindings from those schemas. When you install it, you get the compiled message and service definitions ready to use in your application.

The package enforces backwards compatibility through buf lint validation on stable proto packages, while allowing alpha and beta versions to break compatibility during development. Proto packages are versioned and organized by domain, and the build system automatically excludes unstable versions from released packages. It requires Python 3.11 or later and depends on protobuf, grpcio, and grpc-stubs.

Use it for:

- Define and version protocol buffer schemas for microservices needing cross-process communication.
- Generate Python client bindings from proto definitions to consume gRPC services.
- Maintain backwards compatibility in evolving proto schemas using buf lint validation for stable packages.
- Develop unstable proto packages (alpha/beta versions) during feature development without breaking production consumers.
- Generate Rust bindings from the same proto definitions for polyglot service communication.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides protocol buffer and gRPC schema definitions for cross-process communication, with generated Python and Rust client bindings.

Yes, if you need the gRPC schema definitions this package provides for cross-process communication. The license (FSL-1.1-Apache-2.0) permits internal use and professional services, but restricts commercial offerings that compete with the licensor. Active maintenance and low install friction make it straightforward to adopt. Not relevant for applications outside its intended use.

## Install

pip install sentry-protos
uv add sentry-protos
poetry add sentry-protos

## Installing sentry-protos

Before you install: Low install friction with a pure-Python wheel. Actively maintained with a release 2 days ago. Requires Python 3.11 or later and depends on protobuf, grpcio, and grpc-stubs.

License in practice: Licensed under FSL-1.1-Apache-2.0 (Functional Source License with Apache 2.0 future license). Restricts commercial use that competes with the licensor's offerings until the Apache 2.0 grant takes effect on the second anniversary of release. Internal use and professional services are permitted.

Quickstart:

pip install sentry-protos

from sentry_protos import sentry
import grpcio

Requires Python 3.11 or later. Proto files must define a package matching their filesystem path and end in a version specifier.
