Meet the crew. Every player is a sebbi robot.
3D THAT LOOKS THE PART

Real-time soft shadows, glow, realistic metal, glass, ice and lava, skies with stars, particles and a character that squashes, stretches and blinks.

PLAYS EVERYWHERE

Phones, tablets and computers. Touch stick, keyboard or controller. Quality adjusts itself so it stays smooth on cheap phones.

GUARDIAN BUILT IN

A Help button in every game that reaches a paired parent, Childline and CEOP. Nicknames checked. Break reminders. No tracking, no adverts.

THREE PLACES TO LIVE

On sebbi.pro the moment you publish, on your own domain, and on Roblox in one tap. One game, three homes.

SEBBI SAFE BADGE

Every published version gets a sealed certificate anyone can check. Change the game and it is checked again.

YOUR AI, OR NONE

Pick a template and tune it, or describe your dream game and your own AI designs it. Games are data, never hidden code.

For parents: only let them play sebbi Safe games

Every sebbi Play game has a Guardian Help button. Link it to you and, if your child taps it, you get an email straight away. The alert is sealed so it can't be lost. Nothing your child types is ever sent to us.

Check any game's badge: tap sebbi Safe at the bottom of the screen to open its public certificate. If a game isn't certified, its badge won't link to a certificate.

Questions

Why are the games "data, not code"?

A sebbi Play game is a level design: blocks, coins, checkpoints, a goal and some rules. The sebbi engines turn that into the game. So nobody can hide a script that tracks children, sends them elsewhere or opens a backdoor, because there is nowhere to hide one.

What does Guardian do on Roblox?

Roblox chat keeps its own filter. On top of that, Guardian hides messages that ask for personal details, try to move players to other apps, or match grooming patterns, adds a Guardian safety button with Roblox's report steps and Childline, and a break reminder. It runs on the player's own device: children's messages never leave Roblox.

Do I need Roblox Studio?

No. You create an empty experience once on the Roblox Creator Dashboard, then sebbi Play publishes into it from here every time. You can also download the Roblox file and open it in Studio to add more.

Is my Roblox key safe?

It goes to Roblox for that one publish and is not stored, logged or sealed. Give it only universe-places Write access, and you can delete it on Roblox at any time.
