Bunqueue

11 mentions across 2 sources · 75% positive

Hacker News, Lemmy

What users praise

  • • Zero external dependencies – no Redis, no RabbitMQ, just Bun and SQLite.
  • • Sub-millisecond p99 latency and 150K+ ops/sec on a single node.
  • • Drop-in BullMQ compatible API makes migration easy for existing BullMQ users.
  • • Built-in dead letter queues, cron scheduling, and workflow engine with sagas.

What frustrates them

  • • Single-server only – no clustering, no high availability currently.
  • • Server downtime blocks all queue operations; no failover mechanism.
  • • Tied to Bun runtime – no support for Node.js or Deno.
  • • Very young project (released Jan 2026) – limited production maturity.
