I Tested Every Codex Feature So You Don't Have To (2026)

I tested every feature of OpenAI's Codex App and built a real shipped landing page from scratch — here's the complete walkthrough. Every feature, demoed live, in one tight session.

What's covered:
✓ Setup, UI tour, approval modes
✓ Basic usage — build a real React app from one prompt
✓ Image Generation with GPT-Image-2
✓ Plan mode (clarify before execute)
✓ Code management — commits, rollback, fork, worktrees
✓ AGENTS.md memory (project + global)
✓ Plugins + Automations — GitHub demo + daily cron workflows
✓ Skills — marketplace, third-party, and build-your-own
✓ MCP Servers — Firecrawl live demo
✓ Computer Use — control your Mac from Codex
