This guide is for people who want the easiest setup path.
You do not need to build from source. You do not need Bun. You do not need to understand the full codebase.
If you can copy and paste commands into a terminal, you can set this up.
OpenClaude lets you use an AI coding assistant with different model providers such as:
- OpenAI
- DeepSeek
- Gemini
- Ollama
- Codex
For most first-time users, OpenAI is the easiest option.
You need:
- Node.js 20 or newer installed
- A terminal window
- An API key from your provider, unless you are using a local model like Ollama
- Install OpenClaude with npm
- Set 3 environment variables
- Run
openclaude
- Windows: Windows Quick Start
- macOS / Linux: macOS / Linux Quick Start
Choose this if:
- you want the easiest setup
- you already have an OpenAI API key
Choose this if:
- you want to run models locally
- you do not want to depend on a cloud API for testing
Choose this if:
- you already use the Codex CLI
- you already have Codex or ChatGPT auth configured
After you run openclaude, the CLI should start and wait for your prompt.
At that point, you can ask it to:
- explain code
- edit files
- run commands
- review changes
Cause:
- npm installed the package, but your terminal has not refreshed yet
Fix:
- Close the terminal
- Open a new terminal
- Run
openclaudeagain
Cause:
- the key is wrong, expired, or copied incorrectly
Fix:
- Get a fresh key from your provider
- Paste it again carefully
- Re-run
openclaude
Cause:
- Ollama is not installed or not running
Fix:
- Install Ollama from
https://ollama.com/download - Start Ollama
- Try again
