We shipped a fully integrated AI workflow for building VR on the web. Just describe what you want. AI builds it, tests it, and fixes bugs without you touching the code. Try it yourself here 👉 Discover how it works 🧵👇

The Immersive Web SDK handles physics, hand tracking, grab interactions, and spatial UI out of the box. Now with agentic workflows, your favorite AI coding tool can build on top of that foundation autonomously, moving through scenes, catching bugs, and fixing them. 🪄

To prove it works, we rebuilt Project Flowerbed, a full VR gardening app for the web, from the ground up in 15 hours using AI. The original required tens of thousands of lines of custom code. 😵

Getting started takes one command: "npm create @iwsdk" Open the project in your AI tool, describe what you want to build, and watch it come to life. No headset needed. 🚀 Learn more about the new agentic workflow and get started here 👉 #VR #WebXR #OpenSource

Questions I’d want answered: - Is it truly web-native, or web-wrapped platform-native? - Can users export anything meaningful? - Who owns the generated assets/world logic? - Is the output portable? - How constrained is the runtime? - Is this for toy prototyping, or real deployable worlds? - How fast does it break when the experience gets nontrivial?

do this but for vrc creator companion @VRChat

@MetaHorizonDevs @Scobleizer Finally 🥰

@MetaHorizonDevs Meta, is it another thing to hype and then abandon and screw developers over with?

@MetaHorizonDevs Fully integrated AI workflows like this are exactly what makes building VR on the web faster, smoother, and more creative. Exciting stuff!

@MetaHorizonDevs @melnykowycz Oh yes!

@MetaHorizonDevs 👏

@MetaHorizonDevs Study meta AI integration

@MetaHorizonDevs So is the #unity platform being used on this? $U?

@MetaHorizonDevs I was having this discussion with a friend earlier today about creating VR on the web - it’s a sign, thank you for this!!

Love this direction. “Describe it and ship it” is such a powerful vision for web-based VR, especially for teams that want to prototype fast without getting stuck in the code. この方向性、とても好きです。「説明するだけで形になる」というのは、特に素早く試作したいチームにとってすごく強い価値がありますね。コードで詰まらずに前へ進めるのが大きいです。

@MetaHorizonDevs This looks promising… I've been trying to build something with your sdk but the docs are (or were) so llm-unfriendly it was eating up all my token quota

@MetaHorizonDevs The important part is the loop, not only the prompt: build, test, fix. That is what turns AI from a prompt box into a workflow. Same pattern applies inside teams: define the output, give the tools, run checks, and keep human review where judgment matters.

@MetaHorizonDevs Give my facebook back i cant get to my sister because of u

@MetaHorizonDevs Day 2: Still no response from @Meta support. My case was 'paused' for review, but I have a confirmed Job ID 1449059940038904 proving a location bug. Why is @MetaNewsroom ignoring a @MetaVerified creator in Portugal? This is an urgent payout issue! @Mosseri @CaseyNewton

@MetaHorizonDevs the 'AI builds it, tests it, fixes bugs' loop is the part most AI builders skip. generation is easy, the self-correction pass is what makes it feel magical vs demoware

This is the pattern that keeps repeating: AI collapses the build cycle from weeks to minutes. First it was websites, then mobile apps, now immersive 3D. The real unlock isn't the VR part — it's that "describe what you want" is becoming a universal build interface. We're watching programming become a conversation.

@MetaHorizonDevs The AI builds the VR. The AI tests the VR. The AI fixes the bugs. The developer describes what they want. The developer is still on the payroll. For now. 📡

@MetaHorizonDevs wow, will try for building my world 💕
