ScreenCraft: Automating App Store Screenshot Generation
Building a high-fidelity web canvas designer with serverless asset generation.
Project Profile
Technologies
This project features automated end-to-end regression runs checking auth flows, payment syncs, and telemetry channels prior to production release.
01 / The Challenge
Mobile developers waste hours formatting screenshots, localizing titles, and exporting files at specific dimensions for the App Store and Google Play.
02 / Our Solution
We built a web canvas editor using React 19, DnD Kit, and Three.js. It loads app screenshots into device mockups, translates titles via AI, and generates high-fidelity raster downloads directly on the client using html-to-image.
03 / System Outcome
ScreenCraft shortened the app store asset generation cycle from hours to 5 minutes, and is used internally to ship all Udalov Labs apps.
