  • They diverge on capability: UiPath covers Desktop RPA, Windmill covers Script-to-workflow engine.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

UiPath

  • The Basic plan from $25 per month caps the tenant at 5 Basic users, 5 Plus users, 1 Pro user and 2 unattended robots
  • Basic tenants are hosted only in the European region
  • Only the Basic tier carries a published price; Standard and Enterprise require contacting sales
  • Self healing automation, process simulation, Elastic Robot Orchestration, bring your own encryption keys and dedicated deployments are Enterprise only
  • Agent capability is limited on Basic and requires Standard or Enterprise
  • Extra unattended robots are purchased separately on top of the plan

Windmill

  • Free self-hosted tier caps SSO users at 10 and workspaces at 3, requiring Enterprise for larger teams.
  • Compute unit and seat-based pricing (developer vs. operator seats, worker compute units) adds pricing complexity beyond a flat monthly fee.
  • Email triggers are capped at 100/day on the free tier, limiting event-driven use cases without upgrading.
  • Smaller ecosystem of pre-built integrations compared to more established automation tools like n8n.
