Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

React

  • JSX requires a build step using Webpack, Babel, or other transpilers to convert to browser-executable JavaScript
  • Routing and state management are separate dependencies, not included in core library
  • Configuration complexity for advanced features like server-side rendering without a meta-framework
  • Requires choosing and configuring build tools and development environment setup

SonarQube

  • Advanced Security add-on uses custom pricing
  • Only private project lines of code count toward limits
