What is difference between production and sandbox?

I have a application which is already deployed , I am using sandbox environment. Now, is there any limitation which I’ll face in future if I continue using it ? As Later if I find any, I dont want to migrate all grants to application in production environment. I was not able to find any visible difference between sandbox environment. I love that every connector is already setup for us. In sandbox, so I want to continue using it.

Hi @jka sandbox is limited to 5 grants or connected accounts and is meant solely for testing Nylas. For production, you have to upgrade to one of the paid plans so that you can use the production environment and use your own connector settings.
