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.

Insomnia

  • Git Sync on the free tier covers up to 3 users only
  • Mock servers are capped at 1,000 requests a month on free, then $10 per 25,000
  • Role-based access control requires Pro at $12 per user per month
  • SSO, SCIM and vault integrations are Enterprise only at $45 per user per month
  • Working without an account is limited to the local-only Scratch Pad
