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

Excalidraw

  • Advanced features (unlimited private scenes/folders, cloud storage, access management, presentations, extended AI, team management) are gated behind Excalidraw+
  • Free hosted version persists via scene links/local storage rather than a managed multi-scene workspace
  • Self-hosting the full collaborative stack requires standing up a websocket server and storage beyond the npm editor package
  • No official native desktop or app-store mobile apps - web/PWA only
