Where each one falls short

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

Parabola

  • The Basic plan allows 1 user and 1,000 credits with limited AI
  • No price is published for either the self serve or the business tier
  • Credits are consumed when agents run, and further credits are bought pay as you go
  • Role based access control, SSO, version history and SLAs all sit on the unpriced business 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.
