Compliance and Security Posture: While Windmill Labs is SOC 2 Type II compliant, buyers requiring specific compliance or security postures (e.g., SSO, data-handling specifics) should clarify these before shortlisting, as these might be tied to higher-tier plans or require additional implementation

5

Self-Hosted Usage Caps

high overage

For self-hosted instances, usage against caps embedded in the license key is monitored, and exceeding terms can lead to the key stopping auto-renewal after 35 days if not adjusted or upgraded.

industry

Each agent worker counts as 1 CU on self-hosted (if not used for compute) and 0.5 CU on cloud (if not used for compute)
