OpenAI Codex App vs Claude Code: The AI Coding Agent Showdown (2026)
OpenAI just dropped a bomb on the AI coding space. The new Codex desktop app—launched February 2, 2026—transforms how developers work with AI coding agents. But how does it stack up against Anthropic's Claude Code?
We tested both. Here's what matters.
TL;DR: Quick Comparison
| Feature | OpenAI Codex App | Claude Code |
|---|---|---|
| Price | FREE (ChatGPT Free/Go) | Requires Claude Pro ($20/mo+) |
| Platform | macOS (Windows coming) | macOS, Linux, Windows, WSL |
| Interface | Desktop GUI + CLI | Terminal-first + Desktop |
| Multi-Agent | Yes, parallel agents | Yes, via git worktrees |
| Skills/Extensions | Skills marketplace | MCP (Model Context Protocol) |
| IDE Integration | VS Code extension | VS Code, JetBrains, more |
| Slack Integration | ❌ | ✅ |
| GitHub Actions | ❌ | ✅ |
| Browser Control | ❌ | ✅ Chrome extension |
The Big News: Codex is FREE (For Now)
Here's what caught everyone's attention: OpenAI Codex is now free for ChatGPT Free and Go users for a limited time. Even paid users (Plus, Pro, Business, Enterprise) get doubled rate limits.
Claude Code? Still requires a paid Claude subscription (Pro, Max, Teams, or Enterprise).
Winner for budget-conscious developers: CodexDesktop Experience: The Game Changer
OpenAI Codex App
The new Codex desktop app is built for one thing: managing multiple AI agents.
Key features:
- Multi-agent orchestration: Run multiple agents in parallel, each working on different tasks
- Git worktrees built-in: Each agent works on an isolated copy of your code
- Visual diff review: See and comment on changes without leaving the app
- Skills marketplace: Extend Codex with pre-built skills for Figma, Linear, Cloudflare deployment, and more
- Automations: Schedule agents to run tasks automatically (daily CI checks, issue triage, etc.)
Sam Altman said it best: "Existing IDEs and terminal-based tools are not built to support this way of working."
Claude Code Desktop
Claude Code also has a desktop app, but it's more of a companion to the CLI:
- Diff review interface
- Parallel sessions via worktrees
- Launch cloud sessions
- Integrates with web and mobile
CLI Experience: The Developer's Home
OpenAI Codex CLI
The original Codex launched in April 2025 as a CLI tool. It's still available and syncs with the desktop app:
codex "add dark mode to this app"
Claude Code CLI
Claude Code is terminal-first. That's not a limitation—it's the philosophy:
cd your-project
claude
The Unix philosophy shines here:
tail -f app.log | claude -p "Slack me if you see anomalies"
Extensibility: Skills vs MCP
Codex Skills
OpenAI's answer to extensibility. Skills are bundles of instructions, resources, and scripts:
- Figma: Fetch designs and translate to production UI code
- Linear: Manage issues, track releases, workload
- Cloud deployment: Cloudflare, Netlify, Render, Vercel
- Image generation: GPT Image for game assets, mockups
- Document creation: PDF, spreadsheets, docx
Skills are shareable—check them into your repo for the whole team.
Claude Code MCP (Model Context Protocol)
MCP is Claude Code's extensibility layer:
- Pull from Google Drive, Figma, Slack
- Update Jira tickets
- Connect custom developer tooling
- Browser automation via Chrome extension
Integrations: Where They Diverge
Claude Code Has More Enterprise Integrations
- Slack: Mention Claude in Slack → get PRs back
- GitHub Actions: Automated code review, issue triage
- GitLab CI/CD: Event-driven MR automation
- Chrome: Live debugging, design verification
Codex Focuses on the Agent Loop
- IDE extensions (VS Code)
- Web interface
- CLI
- Desktop app
Multi-Agent Workflows
Both support running multiple agents in parallel with git worktrees. But here's the difference:
Codex App was built for multi-agent orchestration. The entire UI is designed around switching between agent threads, reviewing diffs across agents, and managing parallel work. Claude Code supports it, but you're managing it yourself via terminal sessions or the desktop app's parallel sessions feature. Winner for multi-agent: Codex (purpose-built interface)Real-World Use Case: Building a Game
OpenAI showcased Codex building a full racing game:
- 8 maps
- Multiple racers
- Power-up items
- Used 7 million tokens
- One initial prompt
- Agent acted as designer, developer, AND QA tester (played its own game to find bugs)
This is the kind of long-horizon task that both tools can now handle—but Codex's Skills (image generation + web game development) made it seamless.
