nameko
A microservices framework for Python that lets service developers concentrate on application logic and encourages testability.
Decision gist · record as of 2026-08-14
Yes, with conditions. Nameko is well-suited for greenfield microservices projects or teams already committed to AMQP-based architectures and Python 2.7–3.9. However, maintenance is dormant; do not adopt for new projects requiring active upstream support or modern Python versions beyond 3.9. Existing projects using it are stable, but consider long-term support implications before starting new work.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires AMQP broker (RabbitMQ) for RPC and pub-sub features; HTTP and testing modes work without it.
- Low install friction with a pure-Python wheel distribution.
- Maintenance is dormant—last release was 2021-12-05, though the repository remains active with recent commits and 4754 stars.

What it is and what it does
Nameko is a microservices framework that treats each service as a Python class decorated with RPC, HTTP, or event handlers. It abstracts away the plumbing of inter-service communication (AMQP, HTTP, WebSockets) so developers can focus on business logic. Services are defined declaratively, run via a CLI, and communicate through a message broker or HTTP.
The framework includes utilities for unit and integration testing, a REPL shell for interactive exploration, and support for both synchronous RPC and asynchronous pub-sub patterns. It depends on eventlet for async I/O, kombu for AMQP abstraction, werkzeug for HTTP, and several utility libraries. The codebase supports Python 2.7 through 3.9 according to classifiers, though the last release was in December 2021.
Use it for
- Build a distributed system where multiple services communicate via RPC or pub-sub events over AMQP.
- Rapidly prototype microservices with minimal boilerplate—define a class, decorate methods, run with nameko CLI.
- Write testable service code with built-in mocking and testing utilities for unit and integration tests.
- Expose service logic over HTTP endpoints or WebSockets alongside internal RPC communication.
- Migrate a monolith to services incrementally by extracting business logic into nameko services.
