How to run Claude Code on free models through FCC with Free Claude Code

Point Claude Code at a free NVIDIA NIM model and code from your terminal in about 30 minutes.

Remote script. The install step pipes a script from GitHub directly into sh, so review it first if your policy requires it.

Credentials. Your provider API key is stored in FCC, so use a key you are willing to keep on this machine.

Who it is forA developer who uses Claude Code daily and wants to cut model costs while keeping the same terminal workflow.

The problemClaude Code normally needs a paid model connection, which makes long coding sessions expensive to try.

The outcomeClaude Code runs in the terminal and sends its requests to a model you chose in the FCC Admin UI.

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 Claude Code when prompted.
  2. Run fcc-server on Linux, or open Free Claude Code from the desktop or Start menu on Windows or macOS.
  3. Open the Admin UI URL from the server log, open NVIDIA NIM under Providers, click Add key, paste your key, and click Save.
  4. Leave MODEL on the default or search the dropdown, then click Apply.
  5. Run fcc-claude and select an FCC model from Claude Code's native /model picker.

Prompt for your agent

Using the repo Alishahryar1/free-claude-code, set up FCC with a NVIDIA NIM key stored as <NVIDIA_NIM_API_KEY>, then start `fcc-claude`. Expected output: Claude Code opens and lists an FCC model in /model. Verify that a simple prompt returns a response before reporting success.

Caveat. Free-tier availability and limits are set by each provider and may change, as the README notes.
