We are in the same decision making stage and trying to choose between rabitMQ, Kafka, NATS and some solutions built on top of Redis. Did NATS eventually worked well?

Excellent. We already tested at okayish scale of 5 million messages per minute, with each message being less than 1KiB. Do note that NATS can easily handle 100x this scale. It's just what we had tested during initial days.

  Wow! I have a stupid question - as I understand NATS works very well as a “message” pipe/bus. Anyway to get Redis type cache functionality as well ? Is it something possible ?

    JetStream (not NATS) has a built-in key/value store. Relevant thread (old, from 2023): https://github.com/nats-io/nats.go/discussions/1507 https://github.com/nats-io/nats.go/discussions/1507 someone did some benchmarks in 2025: nats bench kv put --size="128" --msgs 1000000 --storage file 1m3s → Pub stats: 15,656 msgs/sec ~ 1.91 MB/sec nats bench kv get --size="128" --msgs 1000000 59s → Sub stats: 16,720 msgs/sec ~ 2.04 MB/sec I have personally not used this though.

      Thank you! Jetstream looks useful. For a platform which is production our Redis costs are getting prohibitively high. I was on the look for alternatives and perhaps in the software reliability tool [0] I am buildin try out Jetstream. [0] https://github.com/bobinson/vulture https://github.com/bobinson/vulture

        Cool... "vulture" looks pretty good... especially more now-a-days. Thanks.. I also maintain these sites for npm related attacks (since there have been so many since past 1.5 years): 1. Techniques exploited: https://npm-supply-chain-attack-techniques.pagey.site/ https://npm-supply-chain-attack-techniques.pagey.site/ 2.

        I’d also recommend looking at Swytch (docs.getswytch.com, particularly the economics page). Disclosure: I’m a founder.
