Celery is the stronger pick for Python-based systems: it plugs directly into Django, Flask, and FastAPI, and it supports RabbitMQ, Redis, or Amazon SQS as a message broker. Sidekiq wins for Ruby-based systems. It runs natively in Rails, needs only Redis as a broker, and handles jobs with threads inside a single process rather than spinning up separate worker processes.
