Windmill
Windmill is dismantling the paywall between itself and the data stack
A side-by-side editorial comparison of Prowler and rsconnect — release velocity, themes, recent moves, and the top alternatives to consider.
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.
The deployment client is being rebuilt around credentials it never has to store.
rsconnect is the publishing client for Posit Connect and shinyapps.io, and the last year has changed both ends of it. The HTTP layer moved to httr2 and the Connect API to v1; Posit Cloud publishing was removed outright and Posit Connect Cloud added in its place; and authentication picked up identity federation from Posit Workbench, Snowflake-hosted Connect with browser-based auth, and Snowflake connection names read from connections.toml. The most recent release fixes a regression that broke deployment entirely in air-gapped environments.

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.

Two threads run through this. The first is credential elimination — every recent auth change replaces a stored secret with a token the runtime can mint, whether that is Workbench identity federation or a Snowflake connection profile. The second is dependency capture getting stricter about what it actually needs: renv profiles outside the project root, pak-installed packages resolved against configured repositories, and Bioconductor contacted only when a Bioconductor package is genuinely present. Both are the problems you hit deploying inside a regulated network.
Expect the httr2 escape hatch option to be removed once the migration settles, and expect the mcp content category added in 1.10.1 to grow real configuration rather than staying an inferred default.
