- Virtual Dressing Studio — Upload portrait photos and outfit images, select aspect ratios, auto-generate or customize prompts, and see results instantly.

- Cost: 18 credits per AI Try-On generation.
- Visual card grid of all generated outfit try-ons.
- Cards show a thumbnail, aspect ratio, prompt summary, creation date, and status (
processing/completed/failed). - Full-screen viewer modal with a floating overlay of the input photos for reference, along with Download High-Res and Delete Outfit actions.
- Auto-polls every 4 seconds for any items still in
processingstate.
- Four credit packs based on a $1 = 200 credits conversion rate:
- Basic Pack ($5 / 1,000 credits)
- Standard Pack ($10 / 2,000 credits)
- Professional Pack ($20 / 4,000 credits — Most Popular)
- Business Pack ($50 / 10,000 credits)

This architecture is engineered explicitly for Vercel serverless environments.

DATABASE_URL). - Project Creation: Import your GitHub fork into the Vercel dashboard.
- Configure Environment Variables: Copy the variables above into the Vercel project settings environment tab.
- Deploy: Hit "Deploy". Vercel will automatically run the build steps (
npm run build). - Database Push: Run
npx prisma db pushto synchronize database models before launching. - Integrations Setup:
- Establish a Google Cloud OAuth app, enabling the callback URL:
https://your-app.vercel.app/api/auth/callback/google - Setup a Stripe Webhook, pointing to
https://your-app.vercel.app/api/stripe/webhookand selecting thecheckout.session.completedevent. - Register a MuAPI Webhook pointing to

Ready to iterate locally? Setup is straightforward.
- Node.js (v18 or higher)
- A local PostgreSQL instance or a free cloud Database URL.
- ngrok (optional, for local MuAPI webhook testing)
# 1. Clone the repository
git clone https://github.com/SamurAIGPT/ai-tryon
cd ai-tryon
# 2. Install dependencies
npm install
# 3. Setup Environment
cp .env.example .env
# Open .env and insert your specific keys.
# 4. Initialize Database Schema
# Note: Because the database is shared, see the Safety Warning below!
npx prisma generate
npx prisma db push
# 5. Start the Development Server
npm run devThe console should now be active on http://localhost:3000.
Webhook Tip: For local MuAPI webhook testing, run
ngrok http 3000and setWEBHOOK_URLto the generated HTTPS URL in your.env.
The workspace database is shared with other applications. Running npx prisma db push on a clean, empty schema will drop tables belonging to other applications. Always follow the Pull-Declare-Push-Cleanup sequence:
- Run
npx prisma db pullto fetch all database tables. - Declare your
TryOntable and update the relations on theUsermodel. - Run
npx prisma db pushto add your changes safely. - Clean up
schema.prismato keep only NextAuth models,TryOn, and the updatedUserrelations. - Run
npx prisma generateto rebuild the type-safe client.
