Where each one falls short

Neovim

  • No official first-party GUI is shipped; Neovim itself is a terminal-based editor and only maintains a curated list of third-party GUI front-ends
  • Licensing is not uniform: code contributed after commit b17d96 is Apache 2.0, but code carried over from Vim (tagged vim-patch) remains under Vim's own license
  • Built-in LSP client and Tree-sitter integration are frameworks requiring separate configuration or plugins for language servers/grammars to be useful, not out-of-box language support
  • No official iOS, Android, or web build

Rasa

  • Free Developer Edition caps conversations at 1,000 external or 100 internal per company per month
  • Rasa Pro and the Business Plan (Pro plus Studio) are not priced on the site and require contacting sales
