Roblox GUI Maker is a free AI-assisted tool for Roblox Studio creators who need a faster way to plan game interfaces before building them by hand. Describe a menu, HUD, shop, inventory screen, admin panel, onboarding popup, or mobile-first game UI, and it drafts a Roblox-style ScreenGui plan with component hierarchy, layout notes, JSON blueprint, export checklist, and Lua starter code ideas. It is useful for solo Roblox developers, UGC experiences, prototypes, and indie teams that need a practical starting point for usable game UI.

What do DR4, DR3 and the model difference mean?
DR4:
Ahrefs' newer model. It gives more weight to links from sites with organic search traffic and rates a subdomain on its own links.
DR3:
The previous model, shown in the Ahrefs app until 1 December 2026.
Model difference:
DR4 minus DR3 for the same domain. The models calculate differently, so this is not growth or a drop; the “since” lines compare each model with itself.
