One of the advantages of BuildFire is the ability to create custom features (also known as plugins) and add them to your app. You can do this either by creating a developer account and either submit them to the Marketplace or add them directly to your app. If you submit them to the Marketplace, you can even earn additional revenue by selling them to our customer base. If you want to keep your feature proprietary, simply upgrade to a Business plan to add your custom feature.
