Where each one falls short

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

Penpot

  • Smaller user base and community compared to Figma means fewer templates and resources
  • Self-hosting requires Linux server and Docker knowledge for technical setup
  • Real-time collaboration features may have performance issues with very large design files

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.
