Open-source alternative to Claude Agent SDK, ChatGPT Agents, and Manus.
Agentic AI systems, such as Claude Agent SDK (Claude Code) or ChatGPT Agents, can perform meaningful real-world tasks by operating computers, browsers, and phones just like humans. Open source would enhance their capabilities.
Open-Agent.io is an open Agentic AI you can use or modify. Chat with cutting-edge models while our multi-agent system completes your tasks.
Play with it, deploy it, enhance it, or use it as the foundation for your next dedicated agent. We welcome all contributions.

✨ Key Features
💡 Idea
Have your own highly customizable Agentic AI that integrates OpenAI, Claude, Gemini, and open-source models to work together seamlessly!
💬 Stop prompt-chasing. Start decision-making
Spec & context engineering give agents structure to plan, score, and surface options. You stay in control of the final call. Achieve more, struggle less.
🔔 Multi-agent collaboration
Instead of chatting with a single AI, all the frontier models collaborate together to finish your task with our multi-agent framework.
🏠 Self-hostable
Open source and free to modify.
💻 How to deploy
copy .docker/config.example.json and .docker/docker-compose.yml to a separate folder.
mkdir deploy cd deploy cp ../.docker/config.example.json ./config.json cp ../.docker/docker-compose.yml ./docker-compose.yml
Edit config.json and add your API keys. Run with Docker Compose.
docker compose up -d
