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
Svelte
- Licensed under the MIT License per svelte.dev; as open source software it has no paid tier or vendor price to compare
- Svelte is a compiler rather than a runtime library by design, per svelte.dev, so components must be compiled ahead of time and cannot be interpreted directly in the browser without a build step
