A Claude Code-style coding agent that runs anywhere and works with almost any model provider
Decide what you want to achieve with openclaude and check the README on GitHub for requirements before installing.
Clone the repository from GitHub (or take the packaged install route in step 3 if the README offers one).
Follow the project's documented install commands — the Run section below lists the exact ones — and add any required API keys or models.
Work through the README's quickstart example end to end, then adapt it to your own project or data.
Documented setup guides cover many providers, with fast paths for OpenAI-compatible APIs and local Ollama.
Interactive terminal sessions with resume and fork of conversations, plus background sessions.
Built-in web search/fetch tools so the agent can read documentation while it works.
Supports agent definitions and a companion 'buddy' feature described in the README.
Can run as a headless gRPC server for programmatic/embedded use.
An editor extension complements the CLI for in-editor workflows.
Get the OpenClaude source.
git clone https://github.com/Twigpine/openclaude.git
cd openclaudeInstall globally from npm (requires Node.js >= 22).
npm install -g @gitlawb/openclaude@latestFollow the README's fastest setup for OpenAI or local Ollama, then launch the agent in your project.
openclaudeopenclaude is maintained by the Twigpine organization/account on GitHub, together with open-source contributors, in the public repository Twigpine/openclaude.
Yes — the code is open source under the MIT license. You can use, modify and redistribute it under that license's terms.
It depends on the provider you choose: cloud providers need your paid API key, while a local Ollama setup can run with no API key at all.
The official client is Anthropic-only and polished; OpenClaude trades that focus for provider freedom — many APIs plus local models — as a community-maintained derivative.
Clone the repository from GitHub, follow the install commands in the Run section (taken from the project's README), and complete the documented quickstart example before adapting it to your own use case.
