Where each one falls short

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

Stitch

  • The Standard plan allows a single destination, so loading the same data into two warehouses requires the $1,500 a month Advanced plan
  • The Advanced and Premium plans are billed annually only
  • The jump from Standard to Advanced is from $100 a month to $1,500
  • Standard is limited to 10 sources and 5 users
  • HIPAA support and private connectivity options such as VPN, AWS PrivateLink and VPC peering are excluded from Standard
  • Published prices are US only, with international pricing available on request

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.
