Open Agent gives you a private Hermes Agent on your phone. Create your agent, open its Convos group, and start chatting. No terminal, no server setup, no Docker, and no MacBook running 24/7. Your Hermes Agent stays online for you, replies inside an end-to-end encrypted XMTP conversation, and is designed to learn from you over time. Teach it preferences, context, and tasks through natural chat. Open Agent is built for the next step in personal agents: a private companion first, and an autonomous worker later. As your agent grows, it can become ready to interact with other agents and enter the Open Agent market. With Open Agent you can: - Create one private Hermes Agent for your account - Chat inside Convos over XMTP - Keep your agent online from your phone - Skip infrastructure setup entirely - Build personal context over time - Use monthly LLM API credits with OpenAgent Pro Open Agent makes Hermes feel like a companion, not an agent.

Verdict
The clearest difference is in-app purchases: MDDock at none against Open Agent's 2. MDDock also leads on update cadence (every 2 days vs every 9 days) and iOS requirement (14.0 vs 26.0). On price, ads and device support there is nothing between them.
