Store-ready sizes
Generate exact App Store Connect and Google Play dimensions for current phone, tablet, and platform targets.
Features
Screenshot infrastructure exposed as release primitives.
appscreenshotapi is built for teams that want store assets generated from code: validated canvases, a full design system, set-level rendering, compliance linting, localized output, Fastlane folders, async renders, and explicit AI controls.
Fastlane-compatible ZIPs
Download locale folders, deterministic filenames, and screenshots that fit an existing deliver lane.
Localized screenshot sets
Pass locale tags and your own per-locale copy through output.locales to render a full market matrix in one render.
Device frames and design presets
Wrap real captures in real, clay, or flat device frames and style the set with presets, mesh backgrounds, patterns, and typography tokens.
Async renders and webhooks
Run large locale matrices with async: true, then poll GET /v1/renders/{id} or receive signed render callbacks.
AI brief assist
Optionally turn a one-sentence brief into an editable design spec via POST /v1/briefs. The deterministic engine renders it; AI never touches pixels.
