Where each one falls short

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

Helix

  • No official GUI application yet, so it requires comfort with terminal workflows.
  • Plugin ecosystem is far smaller than Vim's or Neovim's, limiting customization.
  • Keybindings differ from both Vim and Kakoune, adding a learning curve for users of either.
  • Configuration is more limited than Neovim's Lua-based extensibility.

SonarQube

  • Advanced Security add-on uses custom pricing
  • Only private project lines of code count toward limits
