Where each one falls short

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

ToolJet

  • Free and Pro tiers cap end users at 50, which may be too low for apps needing broad internal distribution.
  • Enterprise pricing starts at a steep $3,000/month, a large jump from the $199/month Team plan.
  • AI credits reset monthly and do not roll over, penalizing uneven month-to-month usage.
  • Smaller integration and community ecosystem than more established players like Retool.

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.
