Overview

Build and run your own agent platform.

Every team building agents builds the same system from scratch:

• A server to run the agents (batch, streaming, or background mode).
• A database for sessions, runs, traces, and memory.
• Auth and RBAC, validated via JWT on every request.

This system is called the agent platform. Our goal is to build the foundation once so every new agent slots into the same runtime, storage, and connectors.

This guide shows you how to build an agent platform with FastAPI and Postgres.

Managed by coding agents

Because everything lives in one place: agent code, logs, traces, evals, and the live service. Claude Code manages the full lifecycle: create an agent, improve it, extend it, and evaluate it.

Build it step by step

Step	What happens
Run Locally	Run your agent platform (AgentOS + Postgres) locally using docker.
Create an Agent	Use Claude Code to create a new agent.
Improve an Agent	Use Claude Code to read container logs and improve an agent.
Run on Railway	Run your agent platform on Railway.
Run Evals	Lock in behavior with regression tests.
Next Steps	Teams, workflows, scheduling, and Slack interfaces.
