Runtime=Agent Server
The runtime is one of three layers of an agent platform: the SDK to build, the runtime to run, and the control plane to manage. To ship agents to real users, you need to run them as a horizontally scalable, durable service reachable over an API. That’s what the runtime gives you.
AgentOS turns the Agent(...) into a FastAPI app with persistent sessions, JWT-based authentication, observability, and interfaces for Slack, Telegram, and more.
What the runtime gives you
The runtime covers the ground between your agent code and a shipped service:
The same
Agent(...) runs in a script, a test, or an AgentOS service. AgentOS itself is stateless: state lives in db, so you can scale horizontally to handle load.
AgentOS also runs teams and workflows, not only single agents. See Build a
Product.
AgentOS can also serve agents built with the Claude Agent SDK, LangGraph and
DSPy. See Multi-Framework Support.
