Prowler vs Skipper
A side-by-side editorial comparison of Prowler and Skipper — release velocity, themes, recent moves, and the top alternatives to consider.
Prowler vs Skipper: at a glance
What is Prowler?
Prowler's assistant decides what to do with findings; the patches keep the scanner honest
Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.
What is Skipper?
Zalando's ingress proxy finally speaks HTTP/2 cleartext end to end
Skipper ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.57, which enables h2c on the server handler, the proxy client, and the net client, with a new h2c:// route scheme and Kubernetes appProtocol wiring. Everything else in the window is Dependabot traffic and two narrow fixes to token introspection and grant auth.

◆ Current state
Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.
◆ Where it's heading
Two tracks run in parallel and rarely overlap. The minor releases push the commercial agentic surface forward — triage skills, page context, the MCP tool set — while the patches defend the parts everyone uses: dependency resolution, container CVEs, and check correctness. That second track matters more than its version numbers suggest, because a security scanner reporting PASS when an API call failed is worse than one that errors. 5.39.1 fixes exactly that in the ECS task-definition checks, and makes the SES public-access check evaluate every identity policy rather than stopping at the first.
◆ Prediction
Expect the next minor to extend Lighthouse skills to groups of findings rather than one at a time, with patch releases continuing to absorb Trivy and base-image CVE churn.
Skipper
5.0INFRA · APIS
Zalando's ingress proxy finally speaks HTTP/2 cleartext end to end
◆ Current state
Skipper ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.57, which enables h2c on the server handler, the proxy client, and the net client, with a new h2c:// route scheme and Kubernetes appProtocol wiring. Everything else in the window is Dependabot traffic and two narrow fixes to token introspection and grant auth.
◆ Where it's heading
The release cadence is a stream of small, individually unremarkable tags where the occasional protocol or load-balancing change is the only thing worth reading. Recent substance has clustered on the data path: leastRequests balancing in v0.27.53, h2c now. The auth filters are being maintained rather than extended, with fixes rather than new capability.
◆ Prediction
Expect the h2c work to generate follow-up fixes as it meets real gRPC backends, since the release notes already show HTTP Upgrade negotiation failing while direct prior knowledge works.
