Codex vs Claude Code: What I Found After 30 Days
Claude Code vs Codex compared head to head: I build the exact same app with both AI coding agents using the RAMP workflow so you can pick the right tool for your stack without wasting money on the wrong subscription. 🧪 My AI coding courses, live Q&A, weekly builder challenges, direct access to me, and a serious builder community: https://skool.com/agentic-labs 🎁 Get the free 7-Day AI Builder Challenge (RAMP) + resources for this video: https://skool.com/leonvanzyl In this video, I put Claude Code and Codex side by side and have them build the same app, AgentOps, a self-contained visual workflow automation builder similar to a lightweight n8n. You will learn how to run a real agentic coding workflow with the RAMP framework, how to plan and ship a full app with each agent, and how the two compare on UI, architecture, cost, and maintainability using Claude Code, Codex, React, Next.js, and OpenRouter. =========================== Watch This Next =========================== ▶️ OpenAI Codex - Tutorial for Beginners: https://youtu.be/VX3RXec-Ots ▶️ Claude Code Playlist: https://www.youtube.com/playlist?list=PL4HikwTaYE0HQriJw0-lClaJDhdzuUvyc ▶️ OpenAI Codex Playlist: https://www.youtube.com/playlist?list=PL4HikwTaYE0Es7k1EIBUcDEl9vb415uYp =========================== Go Deeper with Agentic Labs =========================== 🧪 AI coding courses, live Q&A, weekly builder challenges, direct access to me, and a serious builder community: https://skool.com/agentic-labs =========================== Tools I Use / Support the Channel =========================== 🚀 Hostinger VPS — use code LEON for 10% off: https://hostinger.com/leon 🚀 Start building with n8n — use my link to support the channel ❤️: https://n8n.partnerlinks.io/f7f19w3vrhin =========================== Subscribe / Connect =========================== Business & sponsorship enquiries: leon@cognaitiv.ai =========================== Question =========================== Which one would you pick for your next build, Claude Code or Codex?

This tutorial is for developers, AI builders, and serious no-code/low-code builders who want practical workflows for building real apps, AI agents, automations, and coding systems. On this channel, I share practical AI engineering and agentic coding workflows using tools like Claude Code, OpenCode, Codex, Cursor, n8n, Next.js, MCP, local AI models, and modern AI development workflows. #agenticcoding #claudecode #codex
