Codex Desktop and its in-app browser feel a bit like OpenAI’s version of Claude Cowork, but with a stronger focus on websites, apps, and internal tools. Claude Cowork was a huge success because it gave non-technical people a way to automate daily tasks and get things done without hiring full-time employees. Codex Desktop takes that same idea and makes it more hands-on for people working with real products. You can open things visually, ask Codex to make changes, test the results, and keep improving them without constantly jumping between your browser, editor, and terminal.
Codex Desktop is basically a workspace where you can get real coding work done without constantly jumping between your editor, browser, terminal, and GitHub. You can ask it to inspect a repo, understand the codebase, make changes, run tests, preview the app in its in-app browser, and fix things based on what you see visually. So instead of just asking for code snippets, you can treat Codex more like a coding teammate that helps you move from “I need to fix this” to an actual working change.
In this guide, we'll explore Codex Desktop and its browser in detail. We will show you how to connect the Codex desktop to a Git repo, create a quick webpage, and preview the app in its in-app browser.
This tutorial teaches you how to:
Download and access Codex Desktop
Create a quick webpage and preview it
Make changes to an app and run tests
Let's get right into it!
