Bullstudio vs Arena | Bullstudio

Arena is a long-standing dashboard for Bull, BullMQ, and Bee-Queue. See how it compares to Bullstudio on scope, setup, and modern BullMQ support.

Arena is one of the original queue dashboards — a web UI that spans Bull, BullMQ, and Bee-Queue. If you're weighing it against Bullstudio, the trade-off is breadth versus depth.

The short version

Arena covers three queue libraries and can connect to multiple Redis instances from one config. If you run a mix of Bull, BullMQ, and Bee-Queue, that breadth is genuinely useful.

Bullstudio focuses on Bull and BullMQ specifically, and invests that focus in deeper job inspection, flow tracing, and a frictionless standalone mode.

At a glance

	Bullstudio	Arena
Queue libraries	Bull, BullMQ	Bull, BullMQ, Bee-Queue
Standalone mode	✅ `npx bullstudio`	✅ via config file
Embedded mode	✅ Express, Fastify, Hono, NestJS, Next.js	✅ as Express middleware
Job inspection	Data, return value, attempts, full stack trace	Data, return value, stack trace
Flow / parent-child tracing	✅ First-class	⚠️ Limited
Setup to first view	One command, no config	Write a JSON config of queues
License	MIT	MIT

Setup

Arena is typically driven by a config that enumerates the queues and connections you want to watch:

{
  "queues": [
    {
      "type": "bullmq",
      "name": "emails",
      "hostId": "Local Redis",
      "redis": { "host": "localhost", "port": 6379 }
    }
  ]
}

That explicit list is handy when you want a curated, persistent view. Bullstudio takes the opposite default — point it at Redis and it discovers your queues for you:

npx bullstudio -r redis://localhost:6379

No config to author before you can look at anything. When you want curation or embedding, the docs cover configuration and framework integration.

Where each one shines

Arena is the better fit if Bee-Queue is in your stack, or you want a single config-driven view spanning several libraries and hosts.

Bullstudio is the better fit if you're all-in on Bull/BullMQ and care about debugging depth — inspecting every attempt of a failed job, tracing flows across queues, and acting on jobs inline — with zero-config standalone access whenever you need it.

Try it

npx bullstudio -r redis://localhost:6379

See the documentation for embedded setup and configuration options.
