Where each one falls short

Notepad++

  • Windows-only, with no official native macOS or Linux build.
  • Lacks built-in debugging or project/build management found in full IDEs.
  • Plugin quality and maintenance varies since they are community-contributed.
  • No built-in version control integration beyond what plugins provide.

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.
