PromptBlox vs Scratch: block coding or a Roblox game?
Scratch is free block coding for stories, games and animations; PromptBlox builds Roblox games from a description. Compare what each makes and who it suits.
Short answer: Scratch is for building projects yourself with code blocks, and PromptBlox is for making a Roblox game from a written description. Scratch projects live and are shared on Scratch. A PromptBlox game becomes a Roblox place file that you open in Roblox Studio to playtest and publish on Roblox.
- Scratch may suit you if you want to make stories, games or animations by arranging every instruction yourself, for free, and share them with the Scratch community.
- PromptBlox may suit you if you are 13 or older, your idea belongs in Roblox, and you want to start from a description instead of building every part by hand.

Turn a Scratch idea into a Roblox game
A Scratch file does not convert into a Roblox place, but the idea behind it can move. Say you made a collecting game in Scratch. In PromptBlox Create, describe it as a Roblox world: “A small garden where players find seeds, carry them to a greenhouse, and see a flower grow after each delivery. The seeds reappear so the loop can repeat.”
PromptBlox makes one concept image as the visual reference, then builds the world and scripts while you watch the Activity feed and a 3D preview. Then refine one thing at a time: “Make the greenhouse visible from the spawn point and keep the delivery counter.” Each saved edit is kept in History.
Pick a build level your plan includes. The Free plan includes Light, which suits a small first version. Pro adds Medium, Max adds High, and Ultra and Ultra+ add Ultra for larger worlds. Bigger builds use more of your weekly allowance and take longer.
Test the rule, then read the script
Export the saved .rbxlx file and open it in Roblox Studio on a Windows or Mac computer. Playtest the loop: collect a seed, deliver it, check the counter and try delivering without a seed. The browser preview shows the layout; the Studio playtest shows whether the rules work.
Then open the script behind the delivery. You will see familiar ideas from Scratch, such as events, variables and conditions, written in Luau, the language Roblox games use. Change one value, predict what will happen and test again. Edits you make in Studio stay in that file and do not sync back into PromptBlox.

Frequently asked questions
Should I choose PromptBlox or Scratch?
Choose Scratch to build stories, games and animations yourself by snapping code blocks together, and to share them in Scratch’s online community. Choose PromptBlox when you want a Roblox game: you describe it, PromptBlox builds it, and you test and publish it with Roblox Studio.
Is Scratch free?
Yes. The Scratch Foundation says Scratch is free for everyone. PromptBlox has a Free plan with Light builds and a small weekly usage allowance, and paid plans from $9.99 a month.
Can PromptBlox convert a Scratch project into a Roblox game?
No. PromptBlox does not import Scratch files. It imports Roblox .rbxlx places only. You can describe your Scratch game’s idea and rules in a new PromptBlox prompt and build a Roblox version from that description.
Do I need to learn Luau before using PromptBlox?
No. You describe the game in plain language and PromptBlox writes the scripts. After you export the game, Roblox Studio lets you read and change those scripts, which is a good way to start learning Luau.
Can younger Scratch users use PromptBlox?
PromptBlox is for ages 13 and up. Users aged 13 to 18 should have a parent or guardian review its terms. Younger creators can keep building in Scratch.
