What is WorkOS?
WorkOS keeps stacking enterprise primitives on top of auth — flags, FGA, MCP, and data pipes.
WorkOS has grown past SSO and directory sync into a broader enterprise-app backbone: fine-grained authorization, feature flags, MCP server auth, and the Pipes data-integration layer now ship alongside the core identity stack. The recent window is dominated by admin-control and developer-ergonomics work — SCIM token rotation, self-serve environments, user-scoped API keys — rather than new categories.
What is Windmill?
Windmill hardens for untrusted multi-tenant workloads while sharpening local DX
Windmill is a developer platform for running scripts, flows, and apps, and its recent releases split between enterprise-grade execution hardening and developer ergonomics. The standout is a daemonless, nsjail-sandboxed container runtime that runs arbitrary images without a Docker socket, isolated enough that Docker scripts are now allowed on Windmill Cloud. Around it sit incremental infra wins: smarter Kubernetes scale-in, inbound distributed tracing, remote SSH execution, and audit-log export.

WorkOS

WorkOS keeps stacking enterprise primitives on top of auth — flags, FGA, MCP, and data pipes.
◆ Current state
WorkOS has grown past SSO and directory sync into a broader enterprise-app backbone: fine-grained authorization, feature flags, MCP server auth, and the Pipes data-integration layer now ship alongside the core identity stack. The recent window is dominated by admin-control and developer-ergonomics work — SCIM token rotation, self-serve environments, user-scoped API keys — rather than new categories.
◆ Where it's heading
Two threads run in parallel: hardening the enterprise-admin surface (token rotation, IT contacts, environments) and extending auth outward to adjacent primitives, including AI-agent infrastructure via MCP server authorization. Pipes opening up to custom providers and the feature-flags runtime client point to WorkOS wanting to own more of the application backbone, not just its front door.
◆ Prediction
Expect continued buildout of the MCP and agent-auth surface plus deeper Pipes connectors; the next visible move is more likely granular access controls or additional first-party integrations than a new product line.

Windmill hardens for untrusted multi-tenant workloads while sharpening local DX
◆ Current state
Windmill is a developer platform for running scripts, flows, and apps, and its recent releases split between enterprise-grade execution hardening and developer ergonomics. The standout is a daemonless, nsjail-sandboxed container runtime that runs arbitrary images without a Docker socket, isolated enough that Docker scripts are now allowed on Windmill Cloud. Around it sit incremental infra wins: smarter Kubernetes scale-in, inbound distributed tracing, remote SSH execution, and audit-log export.
◆ Where it's heading
The direction is making Windmill safe and observable enough for large multi-tenant and regulated deployments: isolation that needs no privileged daemon, autoscaling that protects running jobs, end-to-end traces, and SIEM-ready audit logs. In parallel, the wmill dev live preview and editor integrations lower the friction of authoring locally. Enterprise hardening and self-serve DX are advancing together rather than one at the other's expense.
◆ Prediction
Expect further isolation and observability work, more sandboxing options and broader tracing coverage, plus continued investment in the local-to-cloud authoring loop.
