Detailed Introduction

Open Agents is an open-source reference application designed to streamline the development and deployment of cloud-based AI coding agents on Vercel. It provides a comprehensive three-layer architecture comprising a web UI, an agent workflow runtime, and an isolated sandbox VM. A key architectural decision is the separation of the agent from the sandbox, ensuring agent execution is not tied to a single request, allowing independent lifecycle management, and enabling flexible evolution of models and sandbox implementations. This framework facilitates going from natural language prompts to automated code changes, complete with GitHub integration for version control.
