Where each one falls short

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

KeystoneJS

  • Database support is limited to PostgreSQL, MySQL and SQLite
  • Keystone 5 is a separate legacy product documented on a different site and is not covered by the Keystone 6 docs
  • Upgrading requires following a dedicated Migrate to 8.0.0 guide, so major versions are not drop-in
  • Free support is a community Slack; enterprise-grade consulting and support is a separate paid engagement with Thinkmill and no published price

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
