Sending emails or notifications, processing uploads, running scheduled cron-style jobs, chaining multi-step workflows, fan-out parallel processing.
Any Python application that needs logging — scripts, APIs, workers. Especially good for: colorized console output during development, structured JSON logs for production, automatic exception tracing.
Simple scripts that don't serve web traffic — just use asyncio or threading. If you need sub-millisecond latency, Celery's overhead is too high. For tiny projects, consider RQ (simpler) or FastAPI BackgroundTasks.
If your team's infrastructure is already built around stdlib logging and you can't change it easily — loguru can interop but it adds complexity.
