This week we released Server Authority on Roblox, and it's not just about cheat protection. Due to the deep integration of the technology with our physics and input systems, creators can also craft richer worlds from complex PIT maneuvers to cat wrestling (a critical use case).
Here's what you can do with the new Roblox server auth system! The physics engine participates in SAuth too, so these boneless cats are zero fakery - 100% real sim and forces, no input lag. The "no cheats" bit is barely the point. Should I make a tutorial? #robloxdev

We're unlocking the ability to create rich, diverse, and massive terrain in Roblox Studio. Much more on the way for higher fidelity, roads, paths, and more. We're excited to see what you build.
Our Terrain Early Access program is live. Get an early look at tools that enable larger, more immersive worlds with performance optimizations and up to 64 custom materials. #RobloxDev Learn more and sign up below. devforum.roblox.com/t/early-…

Very excited to see what you all build with this technology. @DavidBaszucki shared it was an idea from early Roblox, and now that it’s here, at edit time and run time, with primitive parts and editables, the possibilities are endless.
Procedural Models are here! Create editable 3D models with code or AI in Roblox Studio. Made with attributes that you can shape and refine. What will you create? devforum.roblox.com/t/studio…

Enhancements released today to the open source MCP Server for Studio allow for complete agentic loops from any MCP client (e.g. Claude Code) to Studio -- prompt to drive complete edit/run/test/stop loops, converging on outcomes. devforum.roblox.com/t/studio…

Over 5M concurrent users in a single game, and more than 16M concurrent users across the platform this morning. Thank you our users, and congratulations to all of our creators and to the infrastructure teams powering this scale. We are just getting started.

We work relentlessly to improve the performance of Roblox, and sometimes, everything gets faster. Over the last 24 hours, we rolled out optimizations to mesh loading yielding automatic, instant, sometimes dramatic wins for every game and experience across the platform.

Analytics is a critical part of the creation flywheel. The better you understand your audience, the better you can make your creations. With funnels and now custom events built in to the platform, creators get access to real power tools out of the box. devforum.roblox.com/t/analyt…

While iteration speeds for developers on Roblox are already fast — you can deploy across mobile, desktop, console, and VR in seconds — we know we can go much faster, and are driving higher quality and performance across our creator tools and the user app.
Play-solo loading just got a lot better. With the latest beta features, load times are now 35% faster for most places. Helping not only people playing experiences in Play-solo mode, but also creators testing for bugs. #RobloxDev devforum.roblox.com/t/improv…
