WorkOS vs Windmill
Side-by-side trajectory, velocity, and editorial themes.
WorkOS ships three new surfaces in a week, pushing into front-end widgets and agent-run admin.
WorkOS is an enterprise identity and auth infrastructure provider, best known for AuthKit, SSO, directory sync, and audit logs. The changelog shows an unusually dense shipping burst: three distinct new product surfaces in a single week, the Widgets API, a Management MCP server, and an API Gateway, layered on top of steady AuthKit feature work like step-up authentication, waitlists, and an Astro integration.
Two directions are visible. First, AuthKit is growing from a backend auth library into a fuller front-end toolkit, adding client widgets, framework SDKs, and richer session flows. Second, the platform is becoming programmable by agents and unified at the edge, via the MCP server and the API Gateway. WorkOS is moving up the stack from backend primitives toward client UI and agent-driven administration.
Expect more AuthKit framework integrations and additional agent-facing tooling built on the MCP server, plus broadening coverage for the newer Widgets API and API Gateway. The pace suggests WorkOS is racing to own both the front-end auth UI layer and the agent-administration layer at once.
Windmill is quietly turning its orchestrator into a DuckLake-native data platform.
Windmill remains a script-and-workflow orchestrator, but its recent output has narrowed almost entirely to the data layer: DuckLake materialization, partitioned assets, freshness, and now schema contracts. The changelog reads less like a general automation tool and more like a managed lakehouse being assembled on top of the existing job engine, with most of the heavier machinery gated to Enterprise Edition.
The direction is a governed, self-maintaining data platform: fork-scoped data environments for isolated iteration, freshness SLAs with an auto-healing watchdog, scheduled compaction and retention, range backfills, and save-time schema validation between producers and consumers. Each release hardens a different operational corner of the DuckLake stack rather than adding breadth, so Windmill is deepening into data-ops rather than widening its surface.
Schema contracts shipped as non-blocking warnings, so the next likely move is to tighten that loop — enforceable contracts or richer lineage on the DuckLake graph. Continued Enterprise gating of the data-ops features (maintenance, freshness watchdog, range backfill) also points to a productized data-platform tier.
