Ship Faster with Codex
summary
Codex is an agent-first IDE with more than 5 million weekly active users using GPT 5.5 to write and validate code, run long-lived workflows via an open-source harness, and call real tools like the Vercel CLI and Chrome DevTools. Demos show Codex fixing a Node version error and redeploying a Next.js site, generating game sprites, running automatic appshots to reproduce onboarding bugs, and running parallel agents that investigate performance and fetch logs successfully.
