App Preview Kit vs Shotbot: automated screenshots compared

Shotbot renders screenshots using a browser automation layer, which adds 30–60 seconds per export. App Preview Kit uses a server-side Playwright + Sharp pipeline that pre-compiles templates, reducing per-screenshot render time to roughly 8 seconds. For a full 47-device export, that's about 6 minutes versus 35+ minutes on Shotbot.

No. Shotbot is a screenshot rendering engine — you provide the screenshots and captions; it composites them into device frames. App Preview Kit generates the captions from your product URL before rendering, so the full pipeline from URL to export is self-contained.

Yes. App Preview Kit provides a REST API and a GitHub Action artifact that fits into Fastlane pipelines. You can trigger a full screenshot export on every new app version, with captions locked to the project brief. Shotbot has similar API integration — the distinction is that App Preview Kit exports AI-generated captions automatically, so no human copy step is needed.
