Composio vs Nango: a developer's comparison for production AI agent integrations (2026)

Composio and Nango are platforms offering distinct approaches for integrating AI agents with tools and APIs. Composio provides a catalog of around 1,000 pre-built tools for AI agents through a managed MCP URL, making it suitable for personal or internal productivity tools that do not require customization beyond the catalog's capabilities. In contrast, Nango is a code-first API integration platform that allows for the creation and deployment of custom tool calls and integrations via coding agents like Claude, Cursor, and Codex. Nango supports over 800 APIs, offering features such as data syncs, webhook processing, and white-label authentication, catering to production AI teams who need customizable, scalable solutions. While Composio's tools are closed source and limited to catalog offerings, Nango's open-source platform provides greater flexibility, allowing for detailed observability and compliance with standards such as SOC 2 Type II, GDPR, and HIPAA. Nango is recommended for AI agents that are integral to customer-facing products due to its ability to handle complex integration needs and scalability, whereas Composio suits simpler, internal agent tasks well.
