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
MUI
- Escaping the Material Design look takes more theming effort than teams expect
- Bundle size is significant, and careless imports pull in far more than needed
- Advanced components such as the full data grid require a paid licence
- Major version upgrades have historically required real migration work

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.
SourceMUI: Is MUI free?
The core library is open source and free. Advanced components, including the full-featured data grid, require a paid licence.
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.
SourceMUI: Can MUI look non-Material?
Yes, through the theming system, but a substantial departure takes real work. Teams wanting full design control often prefer unstyled primitives instead.
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.
SourceMUI: Does MUI handle accessibility?
Components follow WAI-ARIA patterns by default, which is a large part of why teams adopt it.
