With Planning Mode in Roblox Assistant, creators can now take control of complex builds, move from concept to playable faster, and iterate with automated testing and feedback.

Today, we’re introducing Roblox Plus. Launching April 30, this new subscription offers more value, exclusive benefits like free private servers and instant Robux transfers, and more ways for creators to earn. Learn more https://t.co/SZ3I3ap1HT

Sharing, acquiring, and improving the efficiency of human knowledge has never been more personal and convenient.

Our future is so bright and full of possibilities.

Wow, this tweet went very viral!

I wanted share a possibly slightly improved version of the tweet in an "idea file". The idea of the idea file is that in this era of LLM agents, there is less of a point/need of sharing the specific code/app, you just share the idea, then the other person's agent customizes & builds it for your specific needs.

So here's the idea in a gist format: https://t.co/NlAfEJjtJV

You can give this to your agent and it can build you your own LLM wiki and guide you on how to use it etc. It's intentionally kept a little bit abstract/vague because there are so many directions to take this in. And ofc, people can adjust the idea or contribute their own in the Discussion which is cool.

My dear front-end developers (and anyone who’s interested in the future of interfaces):

I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept):
Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow

@nikunj Good one, old friend. 🙇‍♂️

Studio MCP Server now supports full agentic loops, and Assistant can connect to external LLMs via Bring Your Own Key (BYOK). This allows creators to automatically edit, test, and refine their code with AI in plain language on Roblox using their preferred tools.
The simple video shows a full loop with analyze, test, bug found, fix, test, pass.

The new Xbox Ally handheld just dropped, and Roblox creators have been hard at work making sure your favorite games—like RIVALS, 99 Nights in the Forest, Driving Empire, Dandy’s World, Build a Plane, and FRONTLINE VERSUS—are ready to play on day one.

Lights on Roblox can now shine double the distance (60 → 120), making it easier for Creators to light up larger spaces with fewer light sources.

Roblox has broken the record of most concurrent users on a platform, ever, with a peak of 47,296,412 players.

This beats the previous record held by Steam, with them having 41,239,880 players on their platform.

[David Baszucki @DavidBaszucki]

Today over 45M users were on Roblox at the same time, in great games like Steal a Brainrot, Grow a Garden, 99 Nights in the Forest, Blox Fruits, Brookhaven and Dress to Impress (including some fun CCU battles).
