Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Web-based 3D preview for HoloScript-compiled USD robot files

Readme

HoloScript Robotics Studio - Web Preview

Zero-installation 3D robot preview. Type HoloScript, see your robot instantly in the browser.

The Vision

This is Figma for robotics - a web-based IDE that eliminates all barriers to robot authoring:

  • ❌ No expensive GPUs ($1,500+ RTX 4080)
  • ❌ No 10GB installations (Isaac Sim, Gazebo)
  • ❌ No confusing specs (16GB VRAM? Driver versions?)
  • ❌ No desktop-only workflows

Just open a browser and create.

What This Demo Proves

Value Proposition Validated:

  1. Browser-based rendering works (Three.js WebGL)
  2. Robot visualization is instant (no compile wait)
  3. No local GPU needed (cloud rendering path clear)
  4. Shareable URL (send to academics, investors, NVIDIA)

From HoloScript Compiler:

  • Input: two_link_arm.hsplus (40 lines HoloScript)
  • Output: two_link_arm.usd (97 lines USD)
  • Reduction: 58.8% less code

Web Preview Advantage:

  • Renders in browser without USD tools
  • Interactive 3D visualization
  • No installation required
  • Works on any device (even tablets)

Quick Start

# Install dependencies
npm install

# Run development server
npm run dev

# Open browser
http://localhost:3000

Tech Stack

  • Frontend: React 18 + TypeScript
  • 3D Rendering: Three.js + React Three Fiber
  • UI Components: Custom CSS (no framework bloat)
  • Build Tool: Vite (instant HMR)
  • Deployment: Vercel (free tier, instant deploy)

Architecture

HoloScript Code → Compiler → USD File → Web Preview
                                    ↓
                            Three.js Renderer
                                    ↓
                            Browser (WebGL)

Future: Add cloud rendering button → NVIDIA Omniverse streaming

Deployment

# Deploy to Vercel (free)
npm run deploy

# Or manual deploy
vercel --prod

What's Next

Phase 2 Features:

  • [ ] USD file loader (drag-drop .usd files)
  • [ ] URDF export button (multi-format compilation)
  • [ ] Joint sliders (interactive manipulation)
  • [ ] Cloud rendering integration (NVIDIA Omniverse)
  • [ ] Code editor (Monaco/CodeMirror)
  • [ ] Real-time compilation (type HoloScript, see result)

Use Cases

1. NVIDIA Inception Application:

  • Share URL: "See our web-first vision"
  • No installation barrier for reviewers

2. Academic Demos:

  • Professors share URL with students
  • Instant access, zero setup

3. Investor Pitch:

  • Live demo in browser
  • "This is Figma for robotics"

4. Early User Feedback:

  • Share on Twitter/Reddit
  • Validate product-market fit

The Bigger Picture

This web preview is the MVP of the full SaaS product:

Free Tier ($0):

  • Web preview (WebGL rendering)
  • 5 projects
  • URDF export only

Pro Tier ($29/mo):

  • All formats (USD + URDF + SDF + MJCF)
  • 10 hours cloud rendering (Isaac Sim)
  • 500 AI-generated robots/month
  • Collaboration (5 editors)

Enterprise Tier ($299/mo):

  • Unlimited cloud rendering
  • Unlimited AI generation
  • Team workspace
  • On-premise deployment

Market Validation: MATLAB Robotics costs $940/year. Webots costs $4,995. Researchers will pay for superior tooling.


This demo proves the vision is real. Zero installation. Zero GPU requirements. Zero barriers to creation.

Next step: Deploy to Vercel, share URL, start collecting feedback.
