Lima vs Prowler: at a glance
What is Lima?
Lima keeps adding guest operating systems, and a flag to stop AI agents wrecking the host.
Lima's release stream is a steady widening of what it can boot. The 2.1 line added experimental macOS and FreeBSD guests and a limactl shell --sync flag intended to keep AI agents from breaking host files; the 2.2 betas add experimental Windows Server 2025 and Windows 11 guests, TPM emulation under QEMU, a limactl screenshot command, and an option to turn off password-less sudo. Between those, the tags are CLI fixes and template maintenance.
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.

◆ Current state
Lima's release stream is a steady widening of what it can boot. The 2.1 line added experimental macOS and FreeBSD guests and a limactl shell --sync flag intended to keep AI agents from breaking host files; the 2.2 betas add experimental Windows Server 2025 and Windows 11 guests, TPM emulation under QEMU, a limactl screenshot command, and an option to turn off password-less sudo. Between those, the tags are CLI fixes and template maintenance.
◆ Where it's heading
A tool that began as Linux VMs on macOS is becoming a general local virtualization front end, with macOS, FreeBSD, and Windows guests all arriving inside two release lines and much of it contributed through mentorship programs. A second thread is tightening the host boundary, with the sync flag, the sudo opt-out, and TPM emulation all narrowing what a guest can assume or reach. Everything guest-related is still marked experimental.
◆ Prediction
Each guest platform has arrived experimental and then accumulated follow-up pull requests; Windows support is at that stage now, so the next releases most likely stabilize it rather than add another operating system.

◆ 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.
