ESLint
- Slow performance on large codebases compared to newer tools like Oxlint and Biome
- Complexity in configuration from scratch, particularly for TypeScript support
- Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features
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.

Answered from the vendors’ own pages
ESLint: Does ESLint automatically fix code issues?
Many problems ESLint finds can be automatically fixed via the --fix flag. ESLint fixes are syntax-aware so you won't experience errors introduced by traditional find-and-replace algorithms.
SourceHelix: Is Helix free to use?
Yes, Helix is free and open source, licensed under the Mozilla Public License 2.0 (MPL-2.0), with no paid tiers or subscriptions.
SourceESLint: How much does ESLint cost?
ESLint is completely free and open-source software maintained by the OpenJS Foundation. The project accepts voluntary donations from sponsors.
SourceHelix: How do I install Helix?
Install via your operating system's package manager, or download pre-built binaries from GitHub Releases; the nightly version requires building from source.
