Open Agents is an open-source starter template from Vercel Labs designed to help developers build and deploy AI agent applications on modern cloud infrastructure. Rather than starting from scratch with agent routing, tool integration, and streaming UI, developers fork this Next.js-based template and immediately get a working agent app with support for multiple LLM providers, structured tool calling, and real-time response streaming out of the box.
The template ships with a clean, extensible architecture that separates agent logic from UI components. Developers define custom tools as simple functions, configure model providers (OpenAI, Anthropic, Google, and others via the AI SDK), and customize the conversational interface — all within a familiar React and TypeScript codebase. Built-in features include conversation history, error handling, loading states, and responsive design. The project leverages Vercel's AI SDK for unified model access and tool orchestration.
Open Agents deploys natively on Vercel with zero configuration, benefiting from automatic scaling, edge routing, and serverless functions. The project is open-source with 2,700+ GitHub stars and growing adoption among fullstack teams who want to ship agent-powered products without building infrastructure from scratch. It is particularly useful for teams building customer-facing AI assistants, internal productivity tools, or agent prototypes that need to go from idea to production quickly.
