Ask HN: What's your go-to message queue in 2025?
The space is confusing to say the least.
Message queues are usually a core part of any distributed architecture, and the options are endless: Kafka, RabbitMQ, NATS, Redis Streams, SQS, ZeroMQ... and then there's the “just use Postgres” camp for simpler use cases.
I’m trying to make sense of the tradeoffs between:
- async fire-and-forget pub/sub vs. sync RPC-like point to point communication
- simple FIFO vs. priority queues and delay queues
- intelligent brokers (e.g. RabbitMQ, NATS with filters) vs. minimal brokers (e.g. Kafka’s client-driven model)
There's also a fair amount of ideology/emotional attachment - some folks root for underdogs written in their favorite programming language, others reflexively dismiss anything that's not "enterprise-grade". And of course, vendors are always in the mix trying to steer the conversation toward their own solution.
If you’ve built a production system in the last few years:
1. What queue did you choose?
2. What didn't work out?
3. Where did you regret adding complexity?
4. And if you stuck with a DB-based queue — did it scale?
I’d love to hear war stories, regrets, and opinions.
Sidekiq, Sidekiq, Sidekiq (or just Postgres if Im dealing with something trivial)
SQS. For Ruby apps I use Shoryuken with SQS.
Surprised no body is mentioning ActiveMQ!
Kafka for communication between microservices, and MQTT (VerneMQ) for IOT devices
What are your thoughts on Apache Pulsar vs Kafka?
I'm hesitating with EMQx, have you tried it? why did you choose VerneMQ?
NATS
