OpenClaude

OpenClaude is an open-source coding-agent CLI for cloud and local model providers.

Use OpenAI-compatible APIs, Gemini, GitHub Models, Codex OAuth, Codex, Ollama, Atomic Chat, and other supported backends while keeping one terminal-first workflow: prompts, tools, agents, MCP, slash commands, and streaming output.

OpenClaude is also mirrored to GitLawb: gitlawb.com/node/repos/z6MkqDnb/openclaude

Star History

Why OpenClaude

• Use one CLI across cloud APIs and local model backends
• Save provider profiles inside the app with /provider
• Run with OpenAI-compatible services, Gemini, GitHub Models, Codex OAuth, Codex, Ollama, Atomic Chat, and other supported providers
• Keep coding-agent workflows in one place: bash, file tools, grep, glob, agents, tasks, MCP, and web tools
• Use the bundled VS Code extension for launch integration and theme support

Quick Start

Install

npm install -g @gitlawb/openclaude@latest

If you're on Arch Linux, you can install OpenClaude from the community-maintained AUR package:

paru -S openclaude

If the install later reports ripgrep not found, install ripgrep system-wide and confirm rg --version works in the same terminal before starting OpenClaude.

Verify / troubleshoot installed version:

openclaude --version
npm view @gitlawb/openclaude dist-tags
npm install -g @gitlawb/openclaude@latest

Start

Supported Providers

Provider	Setup Path	Notes
OpenAI-compatible	/provider or env vars	Works with OpenAI, OpenRouter, DeepSeek, Groq, Mistral, LM Studio, and other compatible /v1 servers
Hicap	/provider or OpenAI-compatible env vars	Uses api-key auth, discovers models from unauthenticated /models, and supports Responses mode for gpt- models
Gemini	/provider or env vars	Supports API key only
GitHub Models	/onboard-github	Interactive onboarding with saved credentials
Codex OAuth	/provider	Opens ChatGPT sign-in in your browser and stores Codex credentials securely
Codex	/provider	Uses existing Codex CLI auth, OpenClaude secure storage, or env credentials
Gitlawb Opengateway	Startup default, /provider, or env vars	Smart gateway at https://opengateway.gitlawb.com/v1; requires an API key from https://gitlawb.com/opengateway/keys and routes Xiaomi MiMo and GMI Cloud partner models by OPENAI_MODEL
OpenCode Zen	/provider or env vars	Pay-as-you-go AI gateway (43 models); uses OPENCODE_API_KEY via https://opencode.ai/zen/v1; shared key with OpenCode Go
OpenCode Go	/provider or env vars	$10/mo subscription for open models (13 models); uses OPENCODE_API_KEY via https://opencode.ai/zen/go/v1; shared key with OpenCode Zen
Xiaomi MiMo	/provider or env vars	OpenAI-compatible API at https://mimo.mi.com; uses MIMO_API_KEY and defaults to mimo-v2.5-pro
Ollama	/provider or env vars	Local inference with no API key
Atomic Chat	/provider, env vars, or bun run dev:atomic-chat	Local Model Provider; auto-detects loaded models
Bedrock / Vertex / Foundry	env vars	Anthropic-family cloud routes; Vertex is for Claude on Vertex AI, not arbitrary Model Garden models

What Works

• Tool-driven coding workflows: Bash, file read/write/edit, grep, glob, agents, tasks, MCP, and slash commands
• Streaming responses: Real-time token output and tool progress
• Tool calling: Multi-step tool loops with model calls, tool execution, and follow-up responses
• Images: URL and base64 image inputs for providers that support vision
• Provider profiles: Guided setup plus saved user-level provider profile support
• Local and remote model backends: Cloud APIs, local servers, and Apple Silicon local inference

Provider Notes

OpenClaude supports multiple providers, but behavior is not identical across all of them.

• Anthropic-specific features may not exist on other providers
• Tool quality depends heavily on the selected model
• Smaller local models can struggle with long multi-step tool flows
• Some providers impose lower output caps than the CLI defaults, and OpenClaude adapts where possible
• Gitlawb Opengateway is the fresh-install startup default and requires an API key from https://gitlawb.com/opengateway/keys. It uses one OpenAI-compatible base URL; switch between mimo-* and google/gemini-3.1-flash-lite-preview with /model, and do not pin the base URL to /v1/xiaomi-mimo.
• Xiaomi MiMo uses api-key header auth on the direct OpenAI-compatible route and currently does not support /usage reporting in OpenClaude

For best results, use models with strong tool/function calling support.

Agent Routing

OpenClaude can route different agents to different models through settings-based routing. This is useful for cost optimization or splitting work by model strength.

Add to ~/.openclaude.json:

{
  "agentModels": {
    "deepseek-v4-flash": {
      "base_url": "https://api.deepseek.com/v1",
      "api_key": "sk-your-key"
    },
    "zai-default": {
      "model": "glm-5.1",
      "base_url": "https://api.z.ai/api/coding/paas/v4",
      "api_key": "sk-your-key"
    },
    "gpt-4o": {
      "base_url": "https://api.openai.com/v1",
      "api_key": "sk-your-key"
    }
  },
  "agentRouting": {
    "Explore": "deepseek-v4-flash",
    "Plan": "gpt-4o",
    "general-purpose": "gpt-4o",
    "frontend-dev": "zai-default",
    "default": "gpt-4o"
  }
}

When no routing match is found, the global provider remains the fallback.

agentRouting values and explicit Agent tool model overrides match keys in agentModels. By default, that key is also the model string sent to the provider. Set agentModels.<key>.model when you want a local route key such as zai-default to call a different provider model name such as glm-5.1.

Note: /provider changes the global/parent provider for your current session. agentModels and agentRouting are specifically for configuring per-agent provider overrides while keeping the parent session unchanged.

Note: api_key values in settings.json are stored in plaintext. Keep this file private and do not commit it to version control.

Web Search and Fetch

By default, WebSearch works on non-Anthropic models using DuckDuckGo. This gives GPT-4o, DeepSeek, Gemini, Ollama, and other OpenAI-compatible providers a free web search path out of the box.

Note: DuckDuckGo fallback works by scraping search results and may be rate-limited, blocked, or subject to DuckDuckGo's Terms of Service. If you want a more reliable supported option, configure Firecrawl.

For Anthropic-native backends and Codex responses, OpenClaude keeps the native provider web search behavior.

WebFetch works, but its basic HTTP plus HTML-to-markdown path can still fail on JavaScript-rendered sites or sites that block plain HTTP requests.

Set a Firecrawl API key if you want Firecrawl-powered search/fetch behavior:

export FIRECRAWL_API_KEY=your-key-here

With Firecrawl enabled:

• WebSearch can use Firecrawl's search API while DuckDuckGo remains the default free path for non-Claude models
• WebFetch uses Firecrawl's scrape endpoint instead of raw HTTP, handling JS-rendered pages correctly

Free tier at firecrawl.dev includes 500 credits. The key is optional.

Headless gRPC Server

OpenClaude can be run as a headless gRPC service, allowing you to integrate its agentic capabilities (tools, bash, file editing) into other applications, CI/CD pipelines, or custom user interfaces. The server uses bidirectional streaming to send real-time text chunks, tool calls, and request permissions for sensitive commands.

1. Start the gRPC Server

Start the core engine as a gRPC service on localhost:50051:

npm run dev:grpc

Configuration

Variable	Default	Description
GRPC_PORT	50051	Port the gRPC server listens on
GRPC_HOST	localhost	Bind address. Use 0.0.0.0 to expose on all interfaces (not recommended without authentication)

2. Run the Test CLI Client

We provide a lightweight CLI client that communicates exclusively over gRPC. It acts just like the main interactive CLI, rendering colors, streaming tokens, and prompting you for tool permissions (y/n) via the gRPC action_required event.

In a separate terminal, run:

npm run dev:grpc:cli

Note: The gRPC definitions are located in src/proto/openclaude.proto. You can use this file to generate clients in Python, Go, Rust, or any other language.
