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
Playwright
- Requires programming language knowledge; not suitable for non-technical QA staff
- WebKit implementation less mature than Chromium; occasional webkit-specific issues
- Mobile browser testing relies on emulation, not real devices
- No managed cloud infrastructure; users must host CI/CD runners or pay for third-party services
