Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
CodeSandbox
- Detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.
- Focus has shifted toward programmatic sandbox infrastructure, which may be less approachable for casual users just wanting a quick online editor.
- Public sandboxes are visible to others by default, which is not ideal for proprietary code.
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
