Step 1 Web sprite animation technology trend

Step 2 Frontend developers' sprite creation demand

Problem

Indie game web developers and interactive website Freelancers spend 4–8 hours manually arranging frames in Photoshop or Aseprite and hand-writing CSS step() code to create sprite sheet animations for a single character's 4-direction × 3-action sprite sheet, plus an additional 1–2 hours debugging frame spacing errors.

Solution

Drag-and-drop frame images in the browser to automatically generate sprite sheets with real-time preview and auto-generated CSS/JS animation code. AI-powered frame interpolation auto-generates in-between frames, and responsive sizing code is included.

Target: Indie web game developers, interactive website Freelancers (1–5 years experience), frontend bootcamp students

Revenue Model: Premium Plan at 19,000 KRW (~$14.25)/month per account (AI frame interpolation + high-res export). Free tier (5 sheets/month, watermarked). 30% discount for Annual Subscription.
