Overview

Every Python backend that Emergent generates imports from emergentintegrations, a package Emergent ships with the app. Two parts of it matter once you move the app off the platform. emergentintegrations.llm.chat sends your model calls through Emergent's proxy, and emergentintegrations.payments.stripe.checkout wraps Stripe Checkout. Both keep working on your own host if you give them the right key. Both can be replaced with the official SDKs, and the payments swap has one conversion that breaks prices if you miss it.
