Hey there! We support everything from full Next-native CSR/SSR hybrid integrations to simple frontend integrations that just enhance your app and even turnkey last-minute integrations using edge workers.
I might suggest looking at our Next 14 example project if you're wanting to take full advantage of CSR/SSR hybrid testing: https://github.com/growthbook/examples/tree/main/next-js/src/app/client-optimized
Or for something much lighter weight, you can simply embed our script tag and try out our no-code Visual Editor for simple page copy changes:
