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.
