A polyfill that implements the full flexbox specification for browsers with incomplete or buggy implementations.
Reflexie is a polyfill that implements the complete flexbox CSS specification for browsers with incomplete or buggy implementations. It provides a reference implementation based on Google Chrome's behavior and includes comprehensive testing tools to ensure cross-browser compatibility. The project addresses the challenge of inconsistent flexbox support across different browsers.
Frontend developers and web engineers who need reliable flexbox layouts across all browsers, particularly those working on projects requiring consistent layout behavior in Safari, Firefox, and older IE versions.
Developers choose Reflexie because it provides a complete, spec-compliant flexbox implementation with rigorous testing methodology. Unlike simpler polyfills, it uses pairwise test generation to comprehensively cover the complex flexbox specification and treats Chrome as the reference implementation for accuracy.

Implements the complete flexbox specification using Chrome as the reference, ensuring spec-compliant behavior across browsers as detailed in the README.
Uses pairwise algorithms to generate comprehensive test cases, covering the vast flexbox spec thoroughly for cross-browser validation.
Provides live reloading and testbed generation via npm start and grunt watch, streamlining development and testing processes.
Aims for parity with Chrome's flexbox implementation, serving as a reliable benchmark for testing and debugging in other browsers.
The README explicitly states it's 'not ready for prime-time' with unresolved issues and missing features like a proper CSS parsing engine.
Requires cloning with git submodules, npm install, grunt, and Perl for test generation, adding significant setup overhead.
Lacks support for Internet Explorer 10, a key browser for legacy compatibility, as noted in the caveats.
Has issues like clearfix conflicts with display: flex, requiring manual workarounds such as using overflow: hidden.
