A side-by-side editorial comparison of Hatchet and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
Hatchet vs Prowler: at a glance
What is Hatchet?
Hatchet 0.114.2 adds flow-control levers and FIPS images, then spends a day fixing durable stalls.
Hatchet is a task orchestration engine with durable execution, DAGs, and flow control, shipped with Python, Ruby, and Go SDKs. The 0.114.2 minor added pausable rate limits, task-chosen retry timing, FIPS-built server images, and time-partitioned DAG tables. Within hours the team followed with three engine patches and matching SDK releases to stop durable tasks from hanging after a stream reconnect.
What is Prowler?
Prowler 5.46 groups scan findings into issues and extends AI checks to Bedrock and Vertex.
Prowler ships a minor release every one to two weeks. 5.46.0 adds an Issues page to Prowler Cloud that groups a scan's findings into issues with a verdict, new AWS Bedrock, Cognito and WAFv2 checks, a five-check Vertex AI Workbench service on GCP, and checks for PHP runtimes left exposed by the PHP2Shell CVEs across AWS, GCP and Azure. Google Workspace checks now account for the tenant's edition and read the policy Google actually applies.

Hatchet
5.0INFRA · APIS
Hatchet 0.114.2 adds flow-control levers and FIPS images, then spends a day fixing durable stalls.
◆ Current state
Hatchet is a task orchestration engine with durable execution, DAGs, and flow control, shipped with Python, Ruby, and Go SDKs. The 0.114.2 minor added pausable rate limits, task-chosen retry timing, FIPS-built server images, and time-partitioned DAG tables. Within hours the team followed with three engine patches and matching SDK releases to stop durable tasks from hanging after a stream reconnect.
◆ Where it's heading
The work is concentrated on making long-running durable execution reliable at scale: partitioning hot tables, trimming OLAP jobs, and tightening worker acknowledgements. Flow control is getting finer-grained, with rate limits and retries now steerable from inside a task rather than only from config. FIPS images point at regulated, self-hosted buyers.
◆ Prediction
Expect more 0.114.x patches around durable streams and worker acks while the reconnect fix settles. Rate-limit pause has reached Ruby so far; the other SDKs are likely next.
Prowler
5.0INFRA · APIS
Prowler 5.46 groups scan findings into issues and extends AI checks to Bedrock and Vertex.
◆ Current state
Prowler ships a minor release every one to two weeks. 5.46.0 adds an Issues page to Prowler Cloud that groups a scan's findings into issues with a verdict, new AWS Bedrock, Cognito and WAFv2 checks, a five-check Vertex AI Workbench service on GCP, and checks for PHP runtimes left exposed by the PHP2Shell CVEs across AWS, GCP and Azure. Google Workspace checks now account for the tenant's edition and read the policy Google actually applies.
◆ Where it's heading
The open-source engine keeps absorbing coverage where risk is moving: hosted AI services first on Azure in 5.45, now on AWS and GCP, plus fast responses to named CVEs. The paid cloud product keeps adding triage layers on top, from AI fixes per finding to issue grouping, making the free CLI the data source and Prowler Cloud the place findings get worked.
◆ Prediction
Expect AI-service coverage to keep widening across providers and further Prowler Cloud triage features built on the new issue grouping.
