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.
Read the Docs
- Build configuration is finicky, and build failures on dependency changes are a common frustration
- Default themes are recognisable and dated, so sites look alike unless customised
- Private documentation requires a paid business plan
- Build times on large projects are slow enough to interrupt a review cycle
