OpenClaude

Introduction

OpenClaude is an open-source coding-agent CLI that gives developers total freedom over their LLM provider. Launched in April 2026, it exploded to 28k GitHub stars in under 2 months — one of the fastest-growing AI coding tools. Its tagline says it all:

runs anywhere, uses anything

OpenClaude works with OpenAI, Gemini, GitHub Models, Codex, Ollama, or any OpenAI-compatible provider, delivering a consistent terminal-first workflow with prompts, tools, agents, MCP, and streaming output.

Key Features

Multi-Provider Architecture

OpenClaude supports OpenAI-compatible APIs, Gemini, GitHub Models (via interactive onboarding), Codex OAuth, Codex CLI, Ollama (local), Atomic Chat, Gitlawb Opengateway, Xiaomi MiMo, and more. The /provider command provides guided setup and saved provider profiles. You can switch providers mid-session without restarting.

Agent Routing

OpenClaude lets you route different agents to different models through settings-based routing. Route the Explore agent to a cheaper model (DeepSeek) while routing the Planner agent to a more capable one (GPT-5). This enables cost optimization and workload splitting without changing your workflow.

Tool-Driven Workflows

OpenClaude provides a comprehensive tool suite: bash execution, file read/write/edit, grep, glob, agents, tasks, MCP, and slash commands. It handles multi-step tool loops with model calls, tool execution, and follow-up responses. Support for images (URL and base64) is available for vision-capable providers.

Headless gRPC Server

OpenClaude can run as a headless gRPC service, enabling integration with CI/CD pipelines, custom UIs, and other applications. The server uses bidirectional streaming for real-time text chunks, tool calls, and permission requests. A lightweight CLI client is included, and the proto file lets you generate clients in any language.

VS Code Extension

A bundled VS Code extension provides launch integration, a provider-aware control-center UI, and theme support — bringing OpenClaude's capabilities directly into your editor.

Use Cases

OpenClaude excels as a universal coding agent CLI for developers who want to decouple their workflow from a single provider. It is ideal for teams that need flexibility across cloud APIs and local models, cost optimization through provider selection, and CI/CD integration via the gRPC server. Agent routing makes OpenClaude valuable for complex workflows where different tasks benefit from different models.

Verdict

OpenClaude fills a genuine gap: the need for a provider-agnostic coding agent CLI. Its explosive 28k-star growth in 2 months validates that developers want freedom from vendor lock-in. Agent routing, MCP support, and the gRPC server are differentiating features. However, it is young — expect rough edges, variability in tool quality across providers, and a rapidly evolving codebase. For developers who value provider flexibility above all else, OpenClaude is the most promising option in this category.
