celerator

celerator --broker=URI

celerator is a TUI application for real-time debugging and monitoring of Celery tasks. It connects to a Celery broker, listens to task lifecycle events via Celery's built-in event system, and presents them in an interactive terminal interface built with the Textual framework.Features include live event monitoring with real-time task data capture, one-key task retry with original or custom arguments, detailed debug panels for viewing args, kwargs, exceptions and tracebacks, and full keyboard navigation for efficient task inspection.Celery workers must be started with the --events flag for celerator to receive task data.

--broker URI

Celery broker URI (required). Supports Redis, RabbitMQ, and other Celery-compatible brokers.

Celery workers must be started with the --events flag, otherwise celerator will not receive any task data. Requires Python with celery>=5.5.2, textual>=3.2.0, and redis>=6.0.0. No code changes are required in the monitored application.

celerator was created by Fardin Allahverdi and first released as v0.1.0 in May 2025. The name is a portmanteau of "Celery" and "accelerator." It was built to provide a lightweight, terminal-native alternative to web-based Celery monitoring tools like Flower, leveraging the Textual framework for its TUI.
