How to choose AI Agent Integration Platforms
Start with who the agent is acting as. If the agent works on behalf of your end customers inside their own accounts, you need per-user authorisation and a token store, and you should filter for it first; Nango, Composio, Pipedream, Arcade, Scalekit and Zuplo all publish how they hold and refresh a user grant. If instead the agent is a background service calling systems you own, agent identity is the better fit, and Aembit, Keycard and Pomerium issue each agent short-lived access under a policy you write. Next count the applications you actually need. Published catalogues range from several hundred connectors to more than a thousand, and one missing application can cost more engineering time than the rest of the platform saves. Check the list by name before you check the price. Then decide where the credential may live. If the connected accounts hold regulated data, filter for self-hosting and read the deployment notes; Nango, Membrane, Pomerium, Obot and Scalekit all document running inside your own infrastructure. Finally, model the bill at the call volume you expect in month 6, not month 1. A per-connection rate is cheap while you have 50 customers and expensive at 5,000, and a per-agent seat works the other way round. The rate card is the only place that difference shows up.
