Windmill
Windmill is dismantling the paywall between itself and the data stack
A side-by-side editorial comparison of pkgbuild and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
A package whose release calendar is written by whoever ships the next Rtools.
pkgbuild is the layer devtools and pak use to run R CMD build and R CMD INSTALL, and most of what it does is know where the compiler is. Six of its last eight releases are about Rtools: supporting Rtools43, 44 and 45, finding installations that did not come from an installer, reading the Windows registry correctly again, and handling aarch64 Windows when the expected environment variable is unset. The feature surface is a handful of Config/build/* DESCRIPTION options for packages with unusual build needs.
Prowler's assistant stopped explaining findings and started deciding what to do with them.
Prowler ships roughly weekly and the Lighthouse AI thread runs through nearly every release. In 5.35.0 the assistant gained write actions and a side panel; 5.37.0 gave it page-aware context and the full Prowler MCP toolbox, with MCP itself adding integrations, users and roles on both Cloud and self-hosted; 5.39.0 puts a Skills menu on every individual finding. Around that, the paid tier keeps absorbing organizational complexity — Compliance Watchlist, multi-domain SAML SSO, and now Azure management-group onboarding — while 5.37.1 was a pure hardening release that cut the API image's critical CVE count from 18 to 4.

This is maintenance defined entirely by other people's release schedules — R minor versions, Rtools versions, and the DESCRIPTION options downstream package authors ask for. The one structural change worth noting is that on R 4.3 and later the package stopped special-casing Windows and now tests for build tools by compiling a small package, the same way it always has on Unix. That is the direction: fewer platform branches, more probing.
Expect the next release to add support for whichever Rtools ships alongside the next R minor version, and expect the Windows registry lookups to keep shrinking as the compile-probe approach proves out.

Every Lighthouse release moves one step further from answering and closer to deciding. Read-only chat became actions, actions became context-aware, and the newest release attaches named skills to a single finding — including one that judges whether the finding is real and closes it out. The commercial line is drawn consistently: detection and the scanner stay open source, while the agentic layer and multi-tenant onboarding sit behind a Cloud subscription. Every write path is bound to the asking user's RBAC rather than a service identity, which is the same answer given each time the surface widens.
With triage decisions now automatable per finding, the unresolved question these entries raise is bulk: applying a skill across a finding group rather than one at a time, which is where Finding Groups and Systemic Scope already point. Expect the Azure onboarding pattern to be repeated for the remaining providers.
