Where each one falls short

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

Pieces for Developers

  • Requires installing and running a background desktop app rather than being purely cloud-based.
  • Free tier trial of Pro features requires a credit card and reverts after 7 days.
  • Local-first storage means memory is not automatically synced across multiple machines without Enterprise controls.
  • Effectiveness depends on the breadth of integrations enabled, which adds setup overhead.

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.
