Composio

Composio is an integration and tooling platform for AI agents and LLM applications. It provides more than 1,500 integrations, tool discovery, just-in-time tool calls, delegated OAuth, triggers, context management, and a sandboxed workbench. Developers can connect agents built with OpenAI Agents, Anthropic, Vercel AI SDK, LangChain, CrewAI, and other frameworks to external services without implementing every authentication and tool adapter themselves.

✨ Key Features

• Connect agent integrations — Give agents access to a large catalog of external apps and services.
• Discover tools dynamically — Search for relevant tools instead of hard-coding every capability.
• Handle delegated authentication — Manage OAuth and scoped credentials for each user session.
• Execute just-in-time tool calls — Let an agent load and invoke only the tools needed for a task.
• Support agent frameworks — Integrate with OpenAI Agents, Anthropic, Vercel AI SDK, LangChain, CrewAI, and related stacks.
• Create user sessions — Keep per-user connections and permissions separate.
• Use triggers — React to events from connected applications and start workflows.
• Run sandboxed work — Use a sandboxed environment for agent tasks and tool execution.
• Manage secrets securely — Use encrypted credential handling and optional KMS proxy capabilities.
• Add white-label connections — Brand connection pages, with advanced theming available as an add-on.

💳 Pricing

• Hobby — Free, with 100,000 tool calls, 50,000 triggers and 3 team members per month; hard-capped.
• Pro — $29/month, with $29 monthly usage credit, unlimited team members and per-meter spend controls. Unused included credit expires at billing-month end.
• Enterprise — Custom committed-volume and contract terms.
• Zero data retention — On supported features, Pro adds $0.0001 per tool call. The current table does not list the previously cited ZDR trigger-event surcharge.

These plans apply to signups from August 15, 2026. Earlier customers retain their prior plan through December 31, 2026, while premium tool-call charges apply to all customers from September 10. Extra tools, triggers and add-ons are separately metered; use the account-specific schedule.
