This reference covers a list of all the limits that apply on Nango.

​

Free plan

​

Connections

• Limit of 3 connections per integration: On the free plan, users can establish up to three connections per integration if the integration includes scripts.
• Unlimited connections for authentication-only integrations: If an integration is used solely for authentication purposes and doesn’t include scripts, then it can have an unlimited number of connections.

​

Computing resource idling

• 24-hour idling: Computing resources on the free plan are set to idle after 24 hours of inactivity. Once idled, reactivating these resources can cause a one-time delay of a few seconds when the API is called next.

​

Development environment

• Not for production use: The development environment is specifically for testing integrations and is not suitable for production purposes.
• Connection re-authorization requirement: To manage resource usage fairly, connections in the development environment need to be re-authorized every 7 days. This re-authorization can be done through the OAuth flow or by re-entering API credentials.
