bullstudio turns a pile of opaque Redis keys into a live control panel for your BullMQ and Bull queues, so you can see what is stuck, failing, or delayed without opening a Redis CLI. Point it at a Redis URL and it discovers every queue and prefix on its own, including Redis Cluster setups. The overview page tracks waiting, active, delayed, prioritized, completed, and failed counts next to throughput, failure rate, processing time, and queue delay charts. Open any job to read its input data, logs, return value, and stack trace, then retry, promote, or remove it in one click. Flow view draws parent and child jobs as a color-coded dependency graph, which makes it easy to spot the step where a multi-stage job stalled. Separate screens list connected workers with their concurrency and heartbeat, and show repeatable and cron schedules with their next run time. Pause, resume, drain, or clean a queue directly from the header. Basic authentication, a read-only mode, and a base path for reverse proxies keep access under control.
