Composio

Composio lets AI agents take action across more than 1,000 applications by providing integrated tools, managed authentication, and sandboxed execution environments. It resolves which tool to call based on agent intent rather than requiring manual configuration, handles OAuth authentication end-to-end, and preserves context-aware sessions that retain agent state across steps. Composio is model-agnostic, working with Claude, Gemini, and other LLMs, supports bidirectional triggers so external apps can notify agents of events, and offers remote sandboxed Python environments for multi-step workflows. It is used by companies including agent.ai, Zoom, HubSpot, and Letta, and offers free access to get started via dashboard signup, with enterprise plans available through a demo.
