Microcks vs Prowler: at a glance
What is Microcks?
Microcks 1.16 candidate adds IBM MQ mocking and moves to hardened images with faster startup
Microcks 1.16.0-rc1 is the first release candidate since June's 1.15.0-rc1. It adds AsyncAPI mocking and testing for IBM MQ, request/reply handling for Google Pub/Sub with Workload Identity auth, TLS on the HTTP endpoint and external references in the OpenAPI-to-MCP tool converter. The container images switch to Docker Hardened Images by default and replace Spring AOT with a Leyden AOT cache to cut startup time.
What is Prowler?
Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.

Microcks 1.16 candidate adds IBM MQ mocking and moves to hardened images with faster startup
◆ Current state
Microcks 1.16.0-rc1 is the first release candidate since June's 1.15.0-rc1. It adds AsyncAPI mocking and testing for IBM MQ, request/reply handling for Google Pub/Sub with Workload Identity auth, TLS on the HTTP endpoint and external references in the OpenAPI-to-MCP tool converter. The container images switch to Docker Hardened Images by default and replace Spring AOT with a Leyden AOT cache to cut startup time.
◆ Where it's heading
The project keeps broadening the messaging systems it can mock, now reaching enterprise brokers like IBM MQ and Amazon MQ over TLS. In parallel it is reworking its runtime for faster cold starts and smaller attack surface, and the MCP tool converter shows it treating API specs as inputs for AI agents as well as tests.
◆ Prediction
Further 1.16 candidates are likely to fix AOT and hardened-image edge cases, since this candidate already carries several JVM crash and probe fixes tied to that switch.

Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
◆ Current state
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.
◆ Where it's heading
Prowler is moving from configuration checks toward telling teams what is actually exploitable now: Realtime cut the wait for detection, and threat signatures cut the wait for a new check when a vulnerability lands. The free engine keeps the mechanism, while the maintained catalog and issue triage sit in Prowler Cloud.
◆ Prediction
Expect the threat catalog to grow and exploitability issues to reach more providers or link into Realtime alerts in the next releases.
