About VoltAgent

VoltAgent is an open-source TypeScript AI agent framework for building, deploying, and monitoring multi-agent applications. It provides abstractions for agents, tools, memory, and RAG, with built-in support for multiple LLM providers. Agents can be deployed via HTTP using the included Hono server integration.
