Where each one falls short

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

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

shadcn/ui

  • No upgrade path: once copied, upstream fixes and improvements are yours to port by hand
  • Requires Tailwind and React, so it is not an option outside that stack
  • Component code lives in your repository, which grows it and puts maintenance on your team
  • Its popularity has made the default look recognisable, which undercuts the customisation argument

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.

Source
shadcn/ui: Is shadcn/ui free?

Yes, open source and free for commercial use.

ESLint: 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.

shadcn/ui: Why is it not an npm package?

So you own the code. Components are copied into your project, which makes customisation trivial — at the cost of receiving no automatic updates.

ESLint: Can I write custom ESLint rules?

Yes. You can develop custom rules that work alongside built-in functionality through ESLint's plugin system, allowing complete customization for your project needs.

Source
shadcn/ui: Do I need Tailwind?

Yes. Components are styled with Tailwind utility classes and built on Radix primitives, so both are required.
