Composio, Nango and Scalekit Compared on Production Agent Security and Control

A DEV Community piece argues that connecting an AI agent to apps is no longer the hard part, since most platforms now offer broad connector catalogs. The real differentiators are what happens after connection, including credential custody, permission controls, and auditability. The article compares Composio, Nango, and Scalekit on these production concerns, noting Composio's large toolkit catalog and managed OAuth, Nango's self-hostable code-owned model, and Scalekit's per-user accounts and scoped tools. It also references a May 2026 Composio incident in which leaked connected-account tokens affected about 0.3% of active connections. The author concludes that the key question is what a connected agent is allowed to do and what can be proven afterward.
