My current experience with Claude Code vs Codex: Claude Code feels really strong for frontend work — UI, layout, components, fast iterations and understanding the overall product experience. Codex feels stronger for backend work — logic, debugging, refactoring, APIs and making the implementation more controlled. So for me it’s not really about choosing one over the other. I’m starting to use Claude more for frontend/product building and Codex more for backend/review/debugging. Curious if others feel the same: do you split frontend/backend between different AI coding tools, or do you use one tool for everything?
