Where each one falls short

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

GNU Emacs

  • Steep learning curve for its default keybindings and Lisp-based configuration.
  • Default UI looks dated compared to modern editors without heavy customization.
  • Performance can lag on very large files compared to newer editors.
  • Discoverability of features is poor without prior familiarity or external guides.

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.
