Throughput benchmarks are the least useful way to choose. Every option here moves more messages than your service produces. What differs is what happens when something breaks at three in the morning, and how much of that is your problem.
One query that brings people here is temporal vs rabbitmq. Those two do not do the same thing, and the fact that people compare them is the most useful signal in this category.
At a glance
| Product | Type | Best for | Licence | Watch out for |
|---|---|---|---|---|
| RabbitMQ | Broker | The sensible self-run default | BSD-3-Clause | No log semantics |
| Apache Kafka | Broker | Event streaming at scale | Apache-2.0 | Operational commitment |
| NATS | Broker | Lightweight, fast | Apache-2.0 | 14 advisories in 12 months |
| Apache Pulsar | Broker | Multi-tenancy, tiered storage | Apache-2.0 | Complex to operate |
| ActiveMQ | Broker | JMS estates | Apache-2.0 | 9 advisories in 12 months |
| Confluent Cloud | Managed | Kafka without the operations | Proprietary | Usage-based bill |
| Amazon SQS | Managed | A queue, nothing more | Proprietary | Deliberately small feature set |
| Temporal | Durable execution | Workflows with state and time | MIT | Not a broker |
| BullMQ | Job queue | Background jobs, if you run Redis | MIT | Redis dependency |
You are choosing between three things
Brokers move messages between services. Kafka, RabbitMQ, NATS, Pulsar, ActiveMQ, NSQ, ZeroMQ.
Managed platforms are brokers with the operations removed. Confluent Cloud, WarpStream, Redpanda, Google Cloud Pub/Sub, Amazon SQS, Solace.
Durable execution engines run your workflow code with retries, state and timers. Temporal, Inngest, Trigger.dev, BullMQ.
If you want a background job to retry reliably, you want the third group. If you want services to exchange events, the first or second.
Self-run brokers
RabbitMQ
BSD-3-Clause · 13,849 stars · shipped 2026-08-17 · 0 advisories · hybrid with free tier · score 66.9
No recorded advisories, which for a broker of its age and footprint is a genuinely good result.
Verdictthe sensible default if you want a broker, want to run it yourself, and have no specific reason to want a log.
Apache Kafka
Apache-2.0 · 33,699 stars · 0 advisories · score 57.6, confidence 0.51
The event-streaming standard, with the operational commitment that implies.
Verdictright when you need a durable, replayable log. Overkill when you need a queue.
NATS
Apache-2.0 · 20,693 stars · shipped 2026-09-10 · 29 advisories, 14 in the last 12 months (CRITICAL) · 24,884 dependent repos · score 67.8
Lightweight and fast, with the highest recent disclosure rate among the brokers here.
Verdicta good broker that demands a real patch cadence. Not a reason to rule it out, but pinning a version and forgetting about it is not an option.
NATS alternatives
- You want lighter still then nothing here beats NATS. Consider whether you need a broker.
- You want fewer advisories to track then RabbitMQ, which records none.
- You want a log rather than a bus then Kafka, Redpanda or WarpStream.
- You want it managed then Confluent Cloud or Amazon SQS.
ActiveMQ
Apache-2.0 · 2,457 stars · shipped 2026-09-02 · 12 advisories, 9 in the last 12 months (CRITICAL) · score 54.8, confidence 0.23
Verdictrelevant mainly for existing JMS estates. Read the advisories first.
Apache Pulsar
Apache-2.0 · 15,328 stars · shipped 2026-08-03 · 1 advisory, 0 recent · 30 integrations, the most here · score 57.2
Verdictmulti-tenancy and tiered storage are the reasons to take on its complexity.
ZeroMQ and NSQ
ZeroMQ: MPL-2.0, 10,993 stars, last release 2023-10-09. NSQ: MIT, 25,776 stars, last release 2023-12-27. Both record zero advisories.
VerdictZeroMQ is a library, and a stable library shipping rarely is fine. NSQ is a broker, and a broker that has not shipped since December 2023 is a question to answer before building on it.
Managed platforms
Confluent Cloud
From $0.02/GB, usage-based, free tier, 120-day trial · 16 integrations · score 93.1, confidence 0.73
The highest score and confidence combination anywhere on this page. Managed Kafka from the people who largely built Kafka.
Verdictthe strongest managed option on our evidence. You are buying out of operations and into a usage-based bill.
WarpStream and Redpanda
WarpStream: from $0.01/month, 17 integrations, score 74.6. Redpanda: hybrid with free tier, 12,530 stars, 0 advisories, 14 integrations, score 66.2.
Both are Kafka-protocol compatible, competing on cost and operational model rather than API.
Verdictprice these against Confluent specifically. Protocol compatibility makes switching unusually cheap here.
Amazon SQS
Usage-based · 4 integrations · score 51.9, confidence 0.72
That score reflects a deliberately small feature surface, not a poor product.
Verdictif your requirement is genuinely "a queue", this is the lowest-drama answer and usually the right one.
Google Cloud Pub/Sub and Solace
Pub/Sub from $0.27/month with 12 integrations. Solace publishes nothing we could capture (confidence 0.07).
Durable execution, which is what most people actually want
Temporal
MIT · 22,880 stars · shipped 2026-07-08 · 6 advisories, 5 recent (MODERATE) · from $100/month · score 69.0, confidence 0.76
For processes with steps, state and time, rather than a single unit of work.
Verdictthe answer to temporal vs rabbitmq is that they solve different problems. If your work has stages, you want this.
BullMQ
MIT · 9,385 stars · shipped 2026-09-10 · 0 advisories · 1,185 dependent repos · score 57.9
Verdictthe cheapest correct answer if you already run Redis. A job queue, not a workflow engine, which for most background work is the right scope.
Inngest and Trigger.dev
Inngest: Apache-2.0, 5,821 stars, 0 advisories, from $0.50/month. Trigger.dev: from $10/month, hybrid.
Verdictthe developer-experience end of the same space, at lower entry pricing.
Method, and what we could not verify
Confidence runs from 0.07 to 0.76. Managed services score well on pricing and integrations but have no repository or advisory feed; self-run brokers are the opposite.
One figure excluded. Apache Kafka is recorded with 1 dependent repository, which cannot be right against 33,699 stars. We have not used dependency counts in this comparison.
Advisory counts measure disclosure and scale, not quality. Managed services show none because none is published.
We take no vendor payment for placement.
Evaluate these against your own constraints
Eighteen products across three genuinely different jobs. The right one depends on whether you need a broker, a managed platform or a workflow engine, and on who is carrying the pager.
