It lists all 40 tools on this page, ticks the ones found on your machine, and lets you change the selection. Then it installs what is missing (if you say yes) and writes the config for each: Claude Code, Codex CLI, OpenCode, DeepSeek Harness, Crush, Goose, Qwen Code, Aider, Copilot in VS Code, Continue and Zed are configured for you; Cline, Roo Code and Kilo Code are installed and you get their three fields to paste; apps that keep settings in their own window get the exact steps with your key filled in. Every file it changes is backed up first (*.cheapllm-bak).
macOS and Linux (and WSL), in a terminal; needs node or python3. After sh, add -s -- --dry-run to see what it would change, or -s -- --only=claude-code,codex to skip the list. Read the script.
Windows 10 and 11, in PowerShell (Windows PowerShell 5.1 or PowerShell 7). Run $env:CHEAPLLM_DRY_RUN="1" first to see what it would change, or $env:CHEAPLLM_ONLY="claude-code,codex" to skip the list. Read the script.

Anything that lets you set an OpenAI-compatible base URL works: base URL https://cheapllm.shop/v1, your sk-cheap- key, model deepseek-v4.1-flash-1017. If it speaks the Anthropic Messages API, use base URL https://cheapllm.shop with the same key. Stuck? or write to [email protected].
