Codex
- Best for
- Solo builders, fast prototypes, and a lighter first route.
- Less ideal when
- Your team needs to work together from the same shared context right away.
- Choose this if
- You want to get one person productive as quickly as possible.
Short answer: choose Codex if one person wants to move fast. Choose Claude Code if several people need the same starting point, explanation, and shared context.
Codex usually feels lighter for solo builders. Claude Code usually feels safer once team use, handover, and shared context start to matter.
