You are one of the first users to download Power VTT. We are a brand new publisher and the warning will go away once enough users install the platform.
Subscriptions are required if you want to host your games online. Joining an online game does not require a subscription. You do not need a subscription to use the RPG Map Builder, Character Builder, or My Vault.
At the moment, we are built with the right tools to bring you offline functionality but do not guarantee the functionality is 100% complete just yet. We are working hard to bring you offline capabilities so you can create your heros and battlemaps no matter where you are, with or without internet.
Our official support forum is the place to submit and vote on new feature requests, post bugs reports, and get help with questions from the Power VTT team and our growing online community.
