How to run a Codex session on a project folder in the browser with Free Claude Code

Pick a folder in FCC's browser UI and run Codex there, switching models mid-session.

Who it is forA developer who wants to start a coding session from a browser tab, not a terminal.

The problemSetting up a terminal coding agent for every project folder is slow when you only want a quick session.

The outcomeA native Codex session runs against the folder you chose, with real-time and background support.

What you need first

  • A macOS, Linux, or Windows computer with a terminal
  • An API key from at least one provider in the README catalog, such as NVIDIA NIM
  • Permission to run the install script from the README

Steps

  1. Run curl -fsSL "https://raw.githubusercontent.com/Alishahryar1/free-claude-code/main/scripts/install.sh" | sh on macOS or Linux, or the PowerShell command from the README on Windows, and choose Codex when prompted.
  2. Start FCC with fcc-server on Linux, or open Free Claude Code on Windows or macOS.
  3. Open the Admin UI URL from the server log and configure at least one provider.
  4. Choose a folder and start a Codex session in the browser UI.
  5. Switch providers or models inside the same session when needed.

Prompt for your agent

Using the repo Alishahryar1/free-claude-code, start FCC, pick the folder <PROJECT_PATH> in the browser UI, and open a native Codex session. Expected output: Codex answers a question about the folder contents. Verify that the answer references files from <PROJECT_PATH>.

Caveat. The README says switching harnesses inside one session is coming soon, so only provider and model switching works today.
