Where each one falls short

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

Haystack

Requires Python programming knowledge for advanced customization
Steeper learning curve compared to no-code platforms
Community support only on free tier may limit enterprise adoption
Ongoing maintenance dependency for open-source framework

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
