Open-Source Agentic AI

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.

• 💡 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.

1. copy .docker/config.example.json and .docker/docker-compose.yml to a separate folder.

2. Edit config.json and add your API keys.

3. Run with Docker Compose.

We welcome all contributions, ideas, and improvements!
Open issues or pull requests — no bureaucracy, just collaboration.
