nameko

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.

AI-flagged interpretation of the facts on this page — verify before relying

Nameko is a microservices framework for Python that lets you build services as simple classes with RPC, pub-sub events, HTTP endpoints, and WebSocket support, with built-in testing utilities.

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.

Installing nameko

Before you install

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. Suitable for established projects but not for new development requiring active upstream support.

Quickstart

# Install
pip install nameko

# helloworld.py
from nameko.rpc import rpc

class GreetingService:
    name = "greeting_service"
    
    @rpc
    def hello(self, name):
        return "Hello, {}!".format(name)

# Run: nameko run helloworld
# Call from shell: nameko shell
# >>> n.rpc.greeting_service.hello(name="World")

Requires AMQP broker (RabbitMQ) for RPC and pub-sub features; HTTP and testing modes work without it.

Verify before relying

• Current Python 3.10+ compatibility—classifiers list up to 3.9; requires_python is unspecified
• Whether dormant status affects security patching or critical bug fixes going forward
• Production-readiness guarantees given the time elapsed since last release
