OpenClaude
An open-source coding-agent CLI that runs anywhere and uses any model provider.
An open-source, multi-provider AI coding agent CLI that runs anywhere and uses anything — OpenAI-compatible APIs, Gemini, GitHub Models, Codex, Ollama, and more. One terminal-first workflow with prompts, tools, agents, MCP, slash commands, and streaming output.
+ Pros
- Runs anywhere, uses anything — total model/provider flexibility
- 28k GitHub stars in 2 months — explosive community adoption
- Built-in VS Code extension for launch integration
- Agent routing: assign different models to different agent roles
- MCP server support for extensible tool ecosystem
- Provider profiles with guided /provider setup
- Headless gRPC server for CI/CD and custom integrations
- Web search with DuckDuckGo fallback and Firecrawl support
- Open-source with active development (674+ commits)
- Compatible with OpenAI, Gemini, GitHub Models, Codex, Ollama, and more
− Cons
- Young project (launched April 2026) — still maturing
- Custom license — not MIT or Apache
- Tool quality varies significantly across providers and models
- Smaller local models struggle with long multi-step tool flows
- Requires API keys for most providers — not self-contained
- Some Anthropic-specific features are not available on other providers
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.

Vix
Vix is a Go-native, open-source (AGPL-3.0) AI coding agent that slashes token costs by 40-50% using a stem agent architecture and Tree-sitter virtual filesystem. It rethinks the plan/execute loop — keeping LLM cache warm across Explore, Plan, and Execute phases — while shipping Programmable Workflows, Whiteboard Mode with voice AI, MCP server support, and a self-evolving agent that writes its own scheduled jobs and watchers.
