Built for The Grotto
Tell B.O.B. what your game needs. Studio can shape the game around Grotto identity, saves, events, access, and publishing.
Ask B.O.B. to wire in identity, cloud saves, and autosave for returning players.
Track the moments that matter and turn them into Grotto leaderboards.
Add server-checked token or NFT gates when your game calls for them.
Review the exact version you are about to make live on The Grotto.
Know before every run
Studio shows the run quote and asks you to authorize a cap before work begins. Actual usage draws from your USD-valued Studio credits up to that limit; any unused hold is released.
