VR Developer April Roundup: Open Tools, Smarter Profiling, and a Predictable Roadmap

Read time: ~7 minutes

TL;DR

Meta Haptics Studio is now fully open source and available on GitHub. Design haptic experiences once, deploy them across Quest, consoles, mobile, and more.

Meta Quest Runtime Optimizer is baked into Meta Core SDK v203, plus a brand-new AI-powered analysis feature that finds your performance bottlenecks for you.

GDC 2026 sessions are live on-demand, including deep dives on VR development and discovery strategies you can watch right now.

Horizon OS v201 is here with a new versioning system: clearer release naming, new asset pipeline features, and important deprecation heads-ups.

We're investing in new tools and resources to make sure the developers building on it have what they need to create sustainable businesses and jump on emerging opportunities.

This roundup brings together four of those investments, all sharing a common thread: making it easier to build, optimize, and grow on Meta Quest. That means open-source tools you can customize, performance insights that don't require years of prior experience in profiling, knowledge drops from industry experts and some of the most successful teams in VR development, and a cleaner OS roadmap so you can plan ahead without guesswork.

Let's get into it.

Meta Haptics Studio Goes Open Source

If you've tried to build cross-platform haptic experiences, you already know the hurdles: fragmented tooling, platform-specific workflows, and no single design environment that lets you author once and deploy everywhere.

That changes today. Meta Haptics Studio, our free desktop app for designing haptic experiences, is now fully open source. The full design suite (including the SDK which went open source in late 2025, and the Haptics Studio) is now available on GitHub. Fork it. Customize it. Extend it, and contribute to the tool’s evolution.

Why this matters for your projects

The immediate value with this change lies in cross-platform portability. Now you can design a haptic experience once in Haptics Studio and deploy it across Meta Quest, consoles, and through community contributions mobile. From here on out, your haptic design work travels with your project instead of it needing to be platform-specific.

Whether you're a sound designer crafting tactile feedback in FMOD or Wwise, or a developer weaving haptics into a cross-platform game engine, you now have full control over the tool itself, not just the output. If you've been using the Haptics SDK or .haptic file format, this is a natural next step that enables you to customize the design environment that produces those files.

Meta Quest Runtime Optimizer for Unity: Now Built Into Meta Core SDK (With AI-Powered Analysis)

Performance optimization in VR is non-negotiable. In fact, performance matters more in VR than any other medium. Dropped frames don't just look bad; they take people out of the experience and immediately stunt immersion. But hunting down exactly why your app is chugging has historically included a lot of manual profiling, squinting at trace data, and trial-and-error tweaking.

Soon, the Meta Quest Runtime Optimizer will be integrated directly into Meta Core SDK v203. Whether you're building with Unity, Unreal Engine, or another engine that uses Core SDK, you’ll get Bottleneck Analysis and What-if Analysis out of the box. But the real upgrades come from the AI capabilities built into the tool.

AI-powered analysis

The Runtime Optimizer will include its first AI-powered capabilities, enabling you to connect a local LLM CLI tool (like Claude Code or Gemini CLI) and run one-shot performance analysis that combines your trace data with optimization best practices.

Instead of combing through profiling data trying to figure out why you’re missing performance targets, the tool’s new AI capabilities can read it, identify the bottlenecks, and recommend concrete fixes. Whether you're a solo dev without dedicated performance know-how or a larger team looking to speed up your optimization cycles, this upgrade can cut hours out of the profiling process.

What you should do next

Update to Meta Core SDK v203 when it releases in May or download it here now. The Runtime Optimizer will be included automatically.

Try the AI-powered analysis. Connect your preferred local LLM CLI tool and run an analysis pass on your current project.

Dive into the documentation for more details and guidance:

What-if Analysis

📌 Heads up: The standalone Runtime Optimizer package is being deprecated and will no longer receive updates. Your existing standalone installation will continue to work, but all future improvements, including AI-powered analysis, will only be available through Core SDK. If you upgrade to Core SDK v203, you'll need to remove the standalone Runtime Optimizer package to avoid conflicts. Unity will flag this for you during the upgrade process.

GDC 2026: Watch the Sessions You Missed

Not everyone can make it to GDC. And even if you were there, you might have spent your time in meetings, on the expo floor, or in the hallways having much-needed conversations in-person with peers.

We covered a lot at GDC this year, so whether you need a quick refresher on a specific topic or want a top-to-bottom deep dive into every phase of the development cycle, the full GDC 2026 VOD playlist is now live to watch at your leisure.

There are two sessions in particular we recommend to get started:

VR 401: Accelerating Quest Development with Agentic Workflows⁠ | Explore how new AI tools in Unity can automate routine setup, assist with performance and debugging, and improve iteration time so you can focus on gameplay.

VR LiveOps: Sustaining Player Engagement & Monetization⁠ | Discover LiveOps strategies from David Yee (COO, Another Axiom) as he shares the approach fueling Gorilla Tag's long-term engagement, from seasonal content drops to community management.

To be clear, these sessions aren't "here's what we shipped" recaps. They're practical, strategy-level sessions on building better VR experiences and getting them in front of the right players. If you're thinking about ways to build faster or how to grow your audience and revenue on Quest, this is required viewing.

Horizon OS v201: A Clearer Roadmap

Let's start with the structural change, because it affects how you plan going forward.

We're standardizing our OS versioning to replace complex build strings with a straightforward numbering system. Now you’ll see releases labeled as OS 201, 202, 203, and so on. Here is how it works: the first digit represents the platform generation, the following digits indicate incremental updates within it, and decimals are used for hot fixes. For example, you will see sequential updates like v201 and v202 for regular refinements, and v201.1 for minor patches, but we will jump to v300 when there is a major milestone update. This system is designed to give you clearer signals about the scope and impact of each update, allowing you to instantly distinguish between major feature leaps and routine patches. Our goal with these changes is to make critical updates predictable, documentation easier to navigate, and your development roadmap less opaque.

What's new in v201

Beyond the naming convention, this release packs some practical updates:

Meta Asset Library now supports Unity LODGroup prefabs. You can download 3D assets directly as LODGroup prefabs, which streamlines the iteration pipeline.

Eye buffer exclusion from screen recordings. For privacy-sensitive apps, you can now exclude eye buffers from recordings, a useful capability for developers working in enterprise, health, or education spaces.

Bug fixes and stability improvements across the Immersive Debugger, AI Building Blocks, and Interaction SDK.

Browse and download 3D assets as Unity LODGroup prefabs directly from the Meta Asset Library.

Deprecation notices to be aware of

OVRHaptics is being deprecated in favor of newer haptic APIs. (See the Haptics Studio section above; the ecosystem is moving toward open, cross-platform solutions.)

The Virtual Keyboard is being deprecated; we recommend transitioning your projects to the System Keyboard Overlay as a more robust and actively maintained input experience.

What to do next

Review the full Horizon OS v201 release notes

Check whether your project uses OVRHaptics or the Virtual Keyboard and begin planning your migration path.

Wrapping Up

That's a wrap on the first installment of the VR Developer Roundup, a new format to bundle the updates that matter into a single, no-fluff read. The thread connecting all of this: we're investing in making the Quest development ecosystem more open, more intelligent, and more predictable, so you can spend less time wrestling with tools and more time building the thing you set out to build.
