Where each one falls short

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

Bootstrap

  • Default styling is recognisable, so sites can look generic without deliberate customisation
  • Ships a large stylesheet, and unused CSS must be purged to keep payloads reasonable
  • Component-based approach fits less naturally into React and Vue codebases than libraries designed for them

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

Yes, open source under the MIT licence and free for commercial use.

Bootstrap gives finished components and gets you working fastest. Tailwind gives utility classes and more design control, at the cost of building components yourself.

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.

No. Modern versions dropped the jQuery dependency and use plain JavaScript.

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