How Studio works

Watch it take shape
Follow the plan, file changes, live agent log, preview, and cost as the build progresses.
- 04
Play and refine
Try the game in your browser, edit the code, or open another thread to explore a different direction.

Built for The Grotto
The platform work is part of the build.
Tell B.O.B. what your game needs. Studio can shape the game around Grotto identity, saves, events, access, and publishing.
Player progress
Ask B.O.B. to wire in identity, cloud saves, and autosave for returning players.
Events and leaderboards
Track the moments that matter and turn them into Grotto leaderboards.
Owned access
Add server-checked token or NFT gates when your game calls for them.
Preview before publish
Review the exact version you are about to make live on The Grotto.
Know before every run
Set the maximum. Pay for what the build uses.
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.
- Quote before the run
- Live accrued cost
- Spend-only Studio credits
