BullMQ
What BullMQ is
BullMQ is a self-hosted, open-source message queue for Redis and PostgreSQL, intended for background jobs at scale. The standard project uses the MIT license and has no artificial limits on workers or concurrency. Jobs can be delayed or scheduled with cron expressions, fixed intervals, or custom patterns. Automatic retries support exponential backoff, custom strategies, and dead-letter queues. Parent and child jobs can run in parallel, with unlimited nesting, failure propagation options, and result aggregation. Queue or group rate limits and job deduplication support throttling and debounce patterns; group-based limiting is a Pro feature. Listed libraries for Node.js, Bun, Python, .NET, Rust, Elixir, and PHP can share queues. Compatible services include Redis, Valkey, DragonflyDB, AWS ElastiCache, and Upstash. Taskforce.sh provides throughput, latency, queue-health metrics, alerts, search, filtering, debugging, and execution logs. BullMQ Pro adds grouping, batches, observables, and support for Node.js and Bun. The Standard plan costs $1,395 a year or 139.00 USD monthly.
Who it suits
