Composio is a developer-focused platform designed to simplify the integration of AI agents and large language model (LLM) applications with external tools, APIs, and services. It provides a library of over 250 pre-built integrations spanning categories such as CRM, project management, communication, developer tools, and more. Composio handles authentication flows — including OAuth, API keys, and JWT — so developers do not need to implement auth logic themselves. The platform supports multiple AI frameworks including LangChain, LlamaIndex, CrewAI, AutoGen, and OpenAI's function-calling interface. Developers can expose tools to agents as callable functions, enabling agents to take actions in connected services autonomously. Composio also offers a self-hosted deployment option for teams with data-residency or compliance requirements. It is primarily accessed via API and SDK, with Python and JavaScript/TypeScript client libraries available. The platform targets developers and engineering teams building agentic workflows, AI assistants, and automation pipelines that need reliable, production-grade connectivity to third-party services.
