How does Sidekiq compare to Celery (apart from being a different language)? IMHO Sidekiq succeeded, because it works smoother, than other (Ruby-based) task scheduling systems, but can we say the same for Celery? It seems pretty stable and is used in production by many organizations and companies, so the question is, could one do the same for the Python ecosystem, or is Celery just in such a good shape, that it's hard to compete with (considering the same open-core model)?
