Claude Code vs OpenAI Codex : Agent Terminal vs Bac à sable Cloud
Claude Code
L'outil de codage agentique en terminal d'Anthropic
OpenAI Codex
Agent de codage IA cloud autonome — déléguez des tâches, partez, recevez une PR terminée
Verdicts par tâche
Claude Code's terminal-native loop with maker-checker sub-agents gives faster, finer-grained control for developers who want to stay in the driver's seat
Codex is better when you want full autonomy: hand off a task and walk away
Codex runs entire tasks in isolated cloud sandboxes with no developer supervision: parallel PRs across repos, automated testing, no local resource drain
Claude Code can also run autonomously, but its cost compounds in that mode: Anthropic's docs put the average near $13 per developer per active day and agent teams use roughly 7x the tokens in plan mode.
Codex's $20-200/mo subscription tiers cap costs predictably, while Claude Code spend varies with usage
Claude Code's Pro $20/mo tier offers fixed-cost access, but autonomous mode burns tokens rapidly
Codex's cloud sandbox architecture naturally spans repos and environments simultaneously
Claude Code can work across repos but runs locally, limited to one environment at a time
Claude Code runs in the terminal, VS Code, JetBrains, a desktop app and the web, and its terminal and IDE surfaces also support third-party providers, so there is less cloud platform lock-in
Codex requires OpenAI's cloud and proprietary GPT-5-Codex models

Similar tiers, different cost models
Fundamentally different paradigms
Codex for delegation, Claude Code for collaboration
Both SOTA, with different strengths
Claude Code is more portable
