Windmill vs Prowler: at a glance
What is Windmill?
Windmill keeps turning AI clients into the place you build and run its workflows.
Windmill has spent the last six weeks wiring AI into every layer: standalone agents, compaction memory, an AI decision step, Slack-answering agents, and a single /api/mcp endpoint that lets Claude, ChatGPT or Cursor write, test and deploy workspace code. Alongside that it is formalizing who can do what, with default Developer and Operator roles and seat-priced operator build rights. The latest release, Tailwind v4 compilation for full-code apps, is frontend plumbing that makes those apps easier to style.
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.

Windmill keeps turning AI clients into the place you build and run its workflows.
◆ Current state
Windmill has spent the last six weeks wiring AI into every layer: standalone agents, compaction memory, an AI decision step, Slack-answering agents, and a single /api/mcp endpoint that lets Claude, ChatGPT or Cursor write, test and deploy workspace code. Alongside that it is formalizing who can do what, with default Developer and Operator roles and seat-priced operator build rights. The latest release, Tailwind v4 compilation for full-code apps, is frontend plumbing that makes those apps easier to style.
◆ Where it's heading
The direction is clear: Windmill wants to be the execution backend that AI clients drive, not just a UI people click through. MCP moved from a tool list to a build-and-deploy surface, then to interactive cards inside the chat. The roles and seat changes suggest it is preparing to price the wider set of people who can now build through AI.
◆ Prediction
Expect more of the deploy and review lifecycle to surface inside MCP clients, and finer-grained role controls over which MCP tools each role gets.

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.
