License and Python versions

Dramatiq is licensed under the LGPL and officially supports Python 3.10 and later.checked 3 Oct 2026

Message brokers

Dramatiq supports RabbitMQ and Redis out of the box, with RabbitMQ recommended in the installation guide.checked 4 Oct 2026

The cookbook describes error reporting integrations using Rollbar and Sentry.checked 4 Oct 2026

Operating system support

The motivation page lists Windows support, while the installation page says the `watch` extra is supported only on UNIX.checked 3 Oct 2026

Prioritization

Dramatiq supports actor priority after messages are consumed from queues, and RabbitMQ supports queued message priority through an option.checked 3 Oct 2026

Purpose

Dramatiq is a background task processing library for Python focused on simplicity, reliability and performance.checked 4 Oct 2026

Python support

Dramatiq officially supports Python 3.10 and later.checked 4 Oct 2026

Rate limiting

Dramatiq provides rate limiters, with the cookbook showing a Redis-backed concurrent rate limiter.checked 4 Oct 2026

Rate limiting and metrics extras

Optional installation extras provide a Memcached rate limiter backend and Prometheus metrics middleware.checked 3 Oct 2026

Retries

Failed messages are retried automatically with exponential backoff, and retry behavior can be configured per actor.checked 4 Oct 2026

Scheduling

Actors can schedule messages for later using a delay; the guide says scheduled messages should be a small subset of all messages because the broker is not a database.checked 4 Oct 2026

Security and compliance

The official pages opened identify the project license as LGPL and do not state security certifications or compliance claims.checked 4 Oct 2026

Support

The project links to a discussion board and directs questions about cookbook recipes to GitHub issues.checked 4 Oct 2026

Task execution

Actors can enqueue messages to run asynchronously in worker processes, which can run multiple concurrent workers.checked 4 Oct 2026

Testing

Dramatiq provides a StubBroker for unit tests that do not need a running RabbitMQ or Redis instance.checked 3 Oct 2026

What it does

Dramatiq is a background task processing library for Python focused on simplicity, reliability, and performance.checked 3 Oct 2026

Workflow composition

Built-in groups can run actors in parallel and pipelines can chain actors; result management requires result storage to be enabled.checked 4 Oct 2026
