Pre-flight build check & 1-click shareable preview engine for vibe coders. Catch production TypeScript & bundler build errors before deploy, and get instant mobile preview links.
Installation
Launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter.
LaunchWizard is an intent-based pre-flight compiler inspector and 1-click shareable preview engine for VS Code, Cursor, and Antigravity. It completes the DrOpenSource Calm Dev Suite alongside GitWizard and EnvWizard.
⚡ Why LaunchWizard?
Vibe coders and modern AI developers build full-stack apps at lightning speed using Cursor Composer, Claude, and Antigravity. But when it's time to test on a mobile phone or push to production:
The Production Build Trap: Code that runs locally in npm run dev blows up with 200 lines of red compiler errors during next build or vite build on Vercel or Cloudflare.
The "Check My Phone" Friction: Testing mobile responsiveness or sending a quick preview to a friend usually requires setting up ngrok tokens, port forwarding, or pushing half-baked commits to staging.
Cryptic Terminal Panic: Compiler errors like TS2307, TS2322, or Next.js App Router client directive exceptions cause anxiety and derail flow state.
LaunchWizard gives you complete peace of mind before you ship:
3-Second Pre-Flight Radar: Non-destructive dry runs catch every build blocker locally before you push to git.
1-Click Free Cloudflare Preview: Instant secure HTTPS preview link with zero configuration, no accounts, and no credit cards.
In-IDE Mobile QR Code: Scan your screen with your phone camera to test live apps on your device in seconds.
Non-Destructive Compiler Dry Run: Executes tsc --noEmit and static bundle verification in memory.
Client-Side Prefix Shield: Catches client components accessing environment variables without NEXT_PUBLIC_ or VITE_ prefixes before production builds fail.
2. 🌐 1-Click Cloudflare Live Preview & Mobile QR Deck
Zero-Config Public Links: Generates free Cloudflare shareable preview links with end-to-end SSL encryption.
In-IDE SVG QR Code: Scannable QR code generated directly in your sidebar webview.
Status Bar Radar: Live port indicator + instant copyable URL ($(globe) Launch: Live (:3000)).
3. 🗣️ Plain-English Compiler Error Translator
Translates panic-inducing errors into human language:
TS2307 ➔ "Missing Module or File Typo"
TS2322 ➔ "Value Type Does Not Match"
USE_CLIENT_MISSING ➔ "Interactive Hook in Server Component"
