ActiveMQ Alternatives: Seven Options and What Happens to Your JMS Code

The main ActiveMQ alternatives are Apache Artemis, Amazon MQ, IBM MQ, RabbitMQ, Apache Kafka, the managed cloud messaging services and, for JVM teams that already run Valkey or Redis, Redisson PRO. Apache Artemis is the closest: a separate Apache broker with complete JMS 2.0 and Jakarta Messaging 3.1 support that also accepts connections from ActiveMQ's OpenWire clients. Amazon MQ keeps ActiveMQ and takes over running it, and IBM MQ is the long-established commercial JMS broker. RabbitMQ, Kafka and the cloud services change the programming model to different degrees, and Redisson PRO implements JMS without a broker.

Which one fits depends on what happens to your code and to every client that talks to the broker. Most ActiveMQ estates are Java applications that use the JMS API, and the alternatives split three ways on it: some implement the API in full, some implement part of it, and some do not implement it at all.

Redisson is our product, and it is option 7 below, limits included. We checked versions, support status and JMS levels against each vendor's documentation in November 2026.

Which ActiveMQ Are You Replacing?

Until November 2025 the ActiveMQ project shipped two brokers. Classic is the line most people mean by ActiveMQ: versions 5.x and 6.x, configured in activemq.xml, storing messages in KahaDB and speaking OpenWire to its clients. Artemis started as the HornetQ code base, donated to the project, and was meant to succeed Classic eventually. That ended in November 2025, when Artemis became a top-level Apache project in its own right, Apache Artemis, and from 2.50.0 its Maven coordinates moved to the org.apache.artemis group. Classic carries on: 6.4.0 shipped in October 2026.

So "ActiveMQ" now means Classic, and this page is about leaving Classic. Artemis is the first alternative on the list. If you already run Artemis, the options still apply, but the reasons to move are different, because Artemis has none of the JMS 2.0 gaps described next.

Why Teams Look for an ActiveMQ Alternative

ActiveMQ Classic is maintained and widely deployed, and for many estates it is still a reasonable choice. Teams usually start comparing alternatives when one of four things forces an upgrade decision.

• Only three release lines get fixes. ActiveMQ currently maintains three active release lines, 6.4, 6.3 and 5.19, and their latest releases, 6.4.0, 6.3.3 and 5.19.12, all came out in October 2026. The 6.2 line dropped out of maintenance after 6.2.10 that September, joining 6.1, 6.0, 5.18 and every earlier line. Frameworks trail behind: Spring Boot 4.1.2, the current release when this was written, manages ActiveMQ 6.2.10, so an application that takes Spring Boot's version runs a line that no longer gets fixes. Check which version your own Spring Boot release manages.
• Security advisories keep coming. Classic has had 25 so far in 2026, 17 of them rated important. Five of the 25 are code-execution flaws reachable through the web console or Jolokia. One of those, CVE-2026-34197, went into CISA's Known Exploited Vulnerabilities catalogue in April 2026. Version 6.4.0 tightened the default Jolokia access policy and now binds the web console to the loopback interface. Because fixes ship only for active lines, staying covered means upgrading on ActiveMQ's schedule.
• JMS 2.0 support is still incomplete. Classic covers JMS 1.1, and ActiveMQ's own status page calls its JMS 2.0 and Jakarta Messaging 3.1 support partial. In 6.4.0, setting a delivery delay, creating a shared subscription or sending asynchronously with a CompletionListener still throws UnsupportedOperationException, and the failure shows up at runtime, not at compile time. Asynchronous send is planned for 6.5.0, and delivery delay and shared subscriptions for 7.0.0. Our ActiveMQ vs Reliable Queue comparison reproduces the gaps on a 6.4.0 broker.
• The operating model has not changed. Each Classic broker is a JVM writing a KahaDB journal to disk. For high availability, a primary holds a lock on a shared file system or database while a standby waits to take over, and to scale out, brokers join a network and forward messages to one another. The one shared-nothing option, replicated LevelDB, went away in 5.17, so every Classic high-availability design now depends on shared storage.

First, Work Out What ActiveMQ Does for You

ActiveMQ does three different jobs, and the second and third narrow the shortlist before any feature comparison starts.

Job 1: JMS Messaging Between Java Services

Java services exchange messages over queues and topics using the JMS API, usually with Spring's JmsTemplate and @JmsListener on top. Some rely on durable subscriptions, message selectors, scheduled delivery, or XA transactions that commit a message and a database row together. Many use transactions without having asked for them: unless a JTA transaction manager is present, Spring Boot's default listener container runs each @JmsListener call in a transacted session. Most ActiveMQ estates look like this, and this job has the widest choice, because JMS code can move to any provider that implements the calls it makes. What remains to check is the spec level each provider implements and how many ActiveMQ-specific features the code leans on, both covered below.

Job 2: A Protocol Hub for Non-Java Clients

Besides OpenWire, Classic speaks AMQP 1.0, STOMP and MQTT (3.1 and 3.1.1), with STOMP and MQTT also available over WebSocket, and OpenWire itself has non-Java clients: NMS for .NET, still maintained (2.3.0 shipped in October 2026), and CMS for C++, which has not had a release since 3.9.5 in 2019. Once devices, scripts or .NET services talk to the broker directly, JVM-only options drop out at the first step, and the shortlist is whichever brokers speak those protocols.

Job 3: An Embedded Broker

Some applications start ActiveMQ inside their own JVM over the VM transport, as a local buffer or, more often, so that integration tests have a broker without a server. Spring Boot still starts one automatically when activemq-broker is on the classpath and no broker URL is set. This job rarely needs a new platform, and the embedded-broker case below covers what replaces it.

What Survives a Move Off ActiveMQ, and What Doesn't

Code written to the JMS interfaces is portable. A typical ActiveMQ estate also depends on behaviour the specification never defined, and that part stays behind with the broker. Migration estimates that count only JMS calls miss most of this table. Amazon MQ, which runs Classic, keeps most of it.

Start with the second row, because it is a hard filter: .NET or C++ clients on OpenWire need a broker that accepts them, which in practice means staying on ActiveMQ or testing them against Artemis, unless the clients are rewritten. Virtual topics deserve their own search, because they live in destination names rather than in code: a producer sending to VirtualTopic.Orders and a consumer reading Consumer.Billing.VirtualTopic.Orders both look like ordinary JMS.

JMS Support Across the Alternatives

Spec level matters more than it looks, because an incomplete implementation still compiles. Classic is the example: code that sets a delivery delay builds against the JMS 2.0 API and fails when it runs. This table lists what each alternative implements, from each vendor's own documentation.

The JMS broker comparison in our glossary explains the TCK, the specification's conformance suite, and why a full pass matters.

The Seven Alternatives

All seven are the right answer for some team. Each section closes with the situations in which it is a poor fit.

1. Apache Artemis

Artemis comes from the same Apache community as Classic and is its nearest neighbour. It implements Jakarta Messaging 3.1, JMS 2.0 and JMS 1.1 completely, and by default a single acceptor on port 61616 takes AMQP 1.0, MQTT 3.1, 3.1.1 and 5, STOMP, OpenWire and its own Core protocol, so ActiveMQ's Java clients can usually connect without code changes. Version 2.57.0, released in September 2026, needs Java 17 or later. High availability comes from shared storage or replication between a primary and a backup, asynchronous mirroring copies messages to another broker for disaster recovery, and XA transactions are supported.

Artemis publishes a migration guide for Classic users. Virtual topic consumers map onto fully qualified queue names through the virtualTopicConsumerWildcards acceptor parameter, so consumers keep their destination names. Storage does not carry over: the Artemis journal and KahaDB are different formats, and the guide points to a separate export tool, last released in 2020, that converts a KahaDB store for import. The configuration is rewritten as well, from activemq.xml to broker.xml, and Artemis models destinations as addresses with anycast or multicast queues bound to them, which changes how topics are set up. Red Hat sells Artemis as AMQ Broker (AMQ 7.14 is based on Artemis 2.53.0), and independent vendors support it too.

Wrong for you if: the point of the exercise is to stop running a broker, or your topology is a Classic network of brokers. Artemis clusters through its own cluster connections and bridges, so a network of brokers has to be redesigned for it.

2. Amazon MQ for ActiveMQ

Amazon MQ for ActiveMQ is ActiveMQ Classic operated by AWS. The service offers ActiveMQ 5.19 and 5.18, with 5.19, added in February 2026, the recommended version. From 5.18 on, AWS manages patch versions itself and automatic minor version upgrades must stay on. A broker runs as a single instance or as an active/standby pair across two Availability Zones, and several brokers can be joined into a network. Application code and protocols stay as they are. Connection URLs do change, because Amazon MQ exposes TLS endpoints, such as ssl:// on port 61617 for OpenWire. The broker configuration also accepts only the activemq.xml elements AWS permits.

Amazon MQ solves the operating problem only. The engines are 5.x, so at least the JMS 2.0 gaps above apply, and there is no 6.x broker. Amazon MQ offers no Artemis engine either, only ActiveMQ and RabbitMQ. AWS also keeps its own version calendar, so check it rather than ActiveMQ's.

Wrong for you if: your workloads are not on AWS, your code needs JMS 2.0 calls that Classic does not implement, or you are after a lower bill rather than less operational work. On AWS, code that needs those calls can keep them on Redisson PRO, with ElastiCache or MemoryDB as the store, if every client runs on the JVM; see option 7.

3. IBM MQ and Other Commercial JMS Brokers

IBM MQ is the long-established commercial alternative, and it is on a new major version: IBM MQ 10.0 became the long-term support release in June 2026, and 10.0.1 is the latest continuous-delivery release. It implements JMS 2.0 and, since 9.3, Jakarta Messaging 3.0, and IBM says 10.0 supports Jakarta EE 11 applications. A queue manager can take part in XA transactions or coordinate them itself, and IBM MQ has native clients for C, COBOL and .NET alongside Java, plus a z/OS edition. IBM also runs it as a managed service, IBM MQ SaaS, on IBM Cloud or AWS. If your organisation wants one vendor accountable for messaging, it is the usual choice, at the cost of a commercial licence. IBM MQ vs Kafka covers what it gives you that a log does not, and IBM MQ alternatives looks at the opposite move, including the licence models and support end dates that prompt it.

Two other commercial brokers implement JMS. TIBCO EMS 10.5 passes the Jakarta Messaging 2.0 and 3.0 TCKs when its jms_2_0_compliance setting is on, takes part in XA transactions and serves Java, .NET, C and COBOL clients; TIBCO EMS vs Kafka goes into its extensions. The Solace Event Broker is built for event distribution across many protocols, but its JMS API, the Jakarta variant included, implements JMS 1.1 only, so code that calls JMS 2.0 methods does not move to it as written.

Wrong for you if: you want open source, or licence and support cost is the reason you are looking.

4. RabbitMQ

For a JMS estate, the comparison with RabbitMQ turns on how much of JMS you use. RabbitMQ's native model is AMQP 0-9-1, in which producers publish to exchanges, and bindings decide which queues receive each message, a more expressive routing scheme than JMS has. RabbitMQ also speaks AMQP 1.0, plus MQTT and STOMP through plugins bundled with the server. JMS code can reach it two ways. The open-source RabbitMQ JMS Client translates JMS calls into AMQP 0-9-1, and its documentation lists the gaps, including no selectors on queues, no XA, and local transactions that "do not guarantee atomicity". Tanzu RabbitMQ, the commercial edition, added a JMS queue type in 4.3 and JMS topics in 4.4; clients use them over AMQP 1.0 and get broker-side selectors and delivery delay, but no transactions of any kind.

The support model differs too: a RabbitMQ release series gets roughly nine months of community support, and later patches for it go to paying customers. RabbitMQ alternatives compares its JMS routes in detail, and Redis vs RabbitMQ covers it as a broker.

Wrong for you if: your JMS code relies on local or XA transactions, which neither JMS route handles fully, or needs queue selectors and you do not want to pay for Tanzu, or you want long support windows without a contract.

5. Apache Kafka

Kafka is a partitioned, replicated log, not a queue, and it does not implement JMS: moving to it means rewriting every producer and consumer against Kafka's client API. Confluent's own JMS client covers JMS 1.1 only, and Confluent has deprecated it. What you get in return is replay, long retention on disk and very high throughput. Replay alone does not require Kafka: if every reader runs on the JVM and the history fits in memory, a Redisson PRO topic can be rewound as well, as option 7 describes. Share groups, declared production-ready in Kafka 4.2 (February 2026), let consumers acknowledge records one at a time and let a group run more consumers than the topic has partitions, and Kafka 4.4 gave them dead-letter queues, so queue-style consumption is now possible. Message priority, delivery delay, selectors and XA with a database are still missing. Is Kafka a message queue? explains how share groups work, Redis vs Kafka compares the two models, and Apache Kafka alternatives covers the same choice from the other side.

Redpanda speaks the Kafka protocol and shares its model. Apache Pulsar is the log-based option with a JMS route: DataStax's Starlight for JMS implements JMS 2.0 on top of Pulsar, with the jakarta.jms namespace in its current 9.x line, at the cost of running Pulsar's brokers and its BookKeeper storage nodes.

Wrong for you if: your workload is work queues and nothing else, or it depends on priority, delay, selectors or XA.

6. Azure Service Bus, Amazon SQS and Google Cloud Pub/Sub

The managed services take the broker off your hands, and they differ sharply in how much JMS comes with them. On Azure Service Bus Premium, Microsoft's azure-servicebus-jms library provides the JMS 2.0 API over AMQP 1.0. Selectors work except for LIKE and BETWEEN, and so do delivery delay and temporary queues; XA and noLocal do not. The Standard tier offers only a subset of JMS 1.1 aimed at queues. Our Azure Service Bus comparison lists what else it leaves out.

On AWS, SQS and SNS need no servers of your own and charge per request, but the SQS Java Messaging Library implements JMS 1.1 for queues alone, so code that uses topics or JMS 2.0 has to be rewritten. AWS's own JMS broker service is Amazon MQ, option 2. If every client is on the JVM, Redisson PRO can instead keep JMS queues and topics in ElastiCache or MemoryDB, option 7. Our Amazon SQS comparison goes through SQS feature by feature. Google Cloud Pub/Sub has no JMS API. Google does offer a Dataflow template, in beta, that reads from an ActiveMQ JMS server and writes to Pub/Sub, which can serve as a bridge during a migration; Google Pub/Sub vs Redis for messaging covers the service itself. If Kafka, option 5, is the other candidate on Google Cloud, Google Pub/Sub vs Kafka compares the two, including Google's managed Kafka service.

Wrong for you if: you run on premises or across clouds, you need XA, or you need the JMS 2.0 API outside Azure.

7. Redisson PRO on Valkey or Redis

Redisson is a Java client for Valkey and Redis. Its commercial edition, Redisson PRO, includes a JMS provider that implements JMS 2.0 and Jakarta Messaging 3.0 and 3.1; it passes all TCK tests. No broker is involved. Behind the JMS API, each queue is a Reliable Queue and each topic a Reliable PubSub topic, kept in the Valkey or Redis you already operate, whether self-hosted or a managed service such as Amazon ElastiCache or MemoryDB. There are three artifacts, redisson-jms-20 for javax.jms and redisson-jms-30 and redisson-jms-31 for jakarta.jms, so a 5.x application can leave ActiveMQ without the package rename that ActiveMQ 6 would force on it.

Delivery delay and shared durable subscriptions, two of the JMS 2.0 features that throw on Classic 6.4.0, work here, and message priority covers 0 to 9 with nothing to enable. On the native API, a Reliable PubSub subscription can also be rewound to a timestamp or message ID, which an ActiveMQ durable subscription cannot do, provided acknowledged messages are retained. In Spring Boot the switch is a dependency and a connection factory bean built from your RedissonClient, and that bean is also where ActiveMQ's defaults have to be restated, because Redisson's differ:

@Bean
ConnectionFactory connectionFactory(RedissonClient redisson) {
    RedissonConnectionFactory cf = new RedissonConnectionFactory(redisson);
    cf.setQueueConfig("invoices", QueueConfig.defaults()
            // ActiveMQ's default: one delivery plus six redeliveries
            .deliveryLimit(7)
            // ActiveMQ has no visibility timeout; Redisson redelivers a
            // message still unacknowledged after 30 s by default, and each
            // redelivery uses up an attempt, so allow for the slowest message
            .visibility(Duration.ofMinutes(2))
            // ActiveMQ dead-letters to ActiveMQ.DLQ by default; without
            // a name here, a message that runs out of attempts is deleted
            .deadLetterQueueName("DLQ.invoices"));
    return cf;
}
// JmsTemplate, @JmsListener methods and message classes stay as they are

ActiveMQ vs Reliable Queue and Reliable PubSub works through the limits against tested ActiveMQ behaviour.

The PRO licence includes 24x7 support with an SLA for the client, while Valkey or Redis needs its own, and a free trial runs against your own deployment.

Wrong for you if: any non-JVM client connects to ActiveMQ today, your backlog can exceed what you are willing to hold in memory, or you need XA with JMS.

Two Special Cases: MQTT and Embedded Brokers

If ActiveMQ Is Your MQTT Broker

Classic supports MQTT 3.1 and 3.1.1, not MQTT 5. If devices and JMS applications share the broker, Artemis keeps them together and adds MQTT 5. If MQTT is all ActiveMQ does for you, a dedicated MQTT broker is the better fit: Eclipse Mosquitto implements MQTT 5.0, 3.1.1 and 3.1, and EMQX supports MQTT 5.0 and 3.1.1. Kafka and Redisson have no MQTT endpoint of their own.

If ActiveMQ Only Runs Inside Your Application

An embedded broker in a test suite is the easiest case. Spring Boot starts an embedded Classic broker over the VM transport when activemq-broker is on the classpath, and it starts an embedded Artemis broker the same way when the Artemis server artifact is, so moving is a matter of the starter, a few properties and a test run. If the embedded broker stands in for a production broker, consider testing against the production broker's image in a container instead, so the tests exercise the behaviour production has.

ActiveMQ Alternatives Compared

How to Choose

Read the rows in order and stop at the first one that fits.

If You Stay on ActiveMQ Classic

Staying put is a legitimate outcome, particularly for estates with polyglot clients and JMS usage that stops at 1.1. Make it a supported version: move to the newest release of 6.4, 6.3 or 5.19, and keep the web console and Jolokia away from untrusted networks, which 6.4.0's defaults now help with. If you build with Spring Boot, replace the ActiveMQ version it manages with a current one and run your tests:

<properties>
    <!-- Spring Boot 4.1.2 manages 6.2.10, from a line that gets no more fixes -->
    <activemq.version>6.4.0</activemq.version>
</properties>

If you need an SLA behind the broker, third parties such as OpenLogic by Perforce and meshIQ sell support for ActiveMQ Classic.

ActiveMQ Alternatives: Frequently Asked Questions

What Is the Best Alternative to ActiveMQ?

For most teams that want to keep a broker, Apache Artemis: it implements JMS 2.0 and Jakarta Messaging 3.1 in full, accepts OpenWire, so most ActiveMQ Java clients connect unchanged, and documents a migration path from ActiveMQ Classic. Amazon MQ fits better if the problem is operating the broker rather than ActiveMQ itself, and IBM MQ suits organisations that standardise on IBM or need mainframe connectivity. For all-JVM estates that already operate Valkey or Redis, Redisson PRO provides JMS without a broker. Kafka is the right choice only for a replayable log that needs stream processing, readers outside the JVM or more history than fits in memory.

Which Is Better, ActiveMQ or RabbitMQ?

The deciding question is how much of your code uses JMS. ActiveMQ is a JMS broker first, although Classic still lacks some JMS 2.0 features. RabbitMQ routes more flexibly, through exchanges and bindings, and offers JMS only through client libraries: the open-source JMS client lacks XA and selectors on queues, and the fuller JMS queue type, part of the commercial Tanzu edition, supports no transactions, local or XA. JMS-heavy estates usually find Artemis or another JMS provider the closer replacement, while polyglot estates that need flexible routing usually find RabbitMQ the better fit.

Is Kafka Better Than ActiveMQ?

For replay, long retention and very high throughput, yes: Kafka keeps a durable log that many consumer groups read independently. For queue work it is a different tool. Kafka is not a JMS provider, so moving means rewriting every producer and consumer, and it has no message priority, delivery delay, selectors or XA with a database. Share groups, which became production-ready in Kafka 4.2, added per-record acknowledgment, and Kafka 4.4 gave them dead-letter queues, which narrows the gap for work queues without closing it. For replay alone, Redisson PRO is an option too if every reader runs on the JVM and the history fits in memory: its topics can be rewound through its own API.

Is ActiveMQ an MQTT Broker?

Among other things, yes. ActiveMQ Classic supports MQTT 3.1 and 3.1.1, including over WebSocket, alongside OpenWire, AMQP 1.0 and STOMP. It does not support MQTT 5. Apache Artemis supports MQTT 3.1, 3.1.1 and 5, and dedicated MQTT brokers such as Eclipse Mosquitto and EMQX support MQTT 5 as well.

What Are the Disadvantages of ActiveMQ?

For ActiveMQ Classic in 2026: incomplete JMS 2.0 support, with delivery delay, shared subscriptions and asynchronous send throwing UnsupportedOperationException at runtime; a run of 25 security advisories in 2026, several of them code-execution flaws reachable through the web console or Jolokia; high availability that depends on shared storage; and fixes only for the three active release lines, so staying patched means regular upgrades. Its strengths are protocol reach, maturity and the Apache License.

Is ActiveMQ Still Maintained?

Yes. ActiveMQ Classic released 6.4.0, 6.3.3 and 5.19.12 in October 2026, and those are the three lines ActiveMQ lists as active. Older lines, including 6.2 and 5.18, no longer receive fixes. Apache Artemis, which used to be part of the ActiveMQ project, has been a separate Apache project since November 2025 and released 2.57.0 in September 2026.

Is Apache Artemis the Next Version of ActiveMQ?

Not any more. Artemis was developed inside the ActiveMQ project and long presented as its next-generation broker, but in November 2025 it became a separate Apache top-level project, and ActiveMQ Classic continues on its own 6.x line. Artemis is still the most direct path off Classic, with OpenWire support for existing clients and a documented migration guide, but moving to it is a migration to a different broker, not an upgrade.

Is Amazon MQ the Same as ActiveMQ?

Amazon MQ is a managed service that runs ActiveMQ Classic, in versions 5.19 and 5.18, or RabbitMQ. With the ActiveMQ engine, JMS code and protocols work as they do on a broker you run yourself, though clients connect over TLS, and AWS handles provisioning, patch versions and failover between an active and a standby broker. It does not offer Apache Artemis or the ActiveMQ 6.x line.

Next Steps

If Redisson PRO is on your shortlist, ActiveMQ vs Reliable Queue and Reliable PubSub compares it with ActiveMQ Classic feature by feature, with the ActiveMQ behaviour we tested on 6.4.0 and a step-by-step migration. JMS messaging over Valkey and Redis shows the Redisson JMS API in use, and the messaging documentation has the full configuration. A free Redisson PRO trial is available.
