One request in. A store-ready ZIP out.

Send raw captures with the device sizes and locales you need. appscreenshotapi frames, resizes, localizes, and returns a Fastlane-ready archive. No UI step in the loop.

The output

Every size each store demands, framed and ready to upload.

appscreenshotapi returns the exact dimensions App Store Connect and Google Play require — one source capture fans out across devices and locales.

Built for pipelines

Infrastructure, not a screenshot editor.

Everything a mobile team needs to keep store listings current — exposed as primitives you call from code.

Store-ready sizes

Exact App Store Connect and Google Play dimensions for every device class — validated before they ever hit review.

iphone_6_7 · ipad_13 · pixel_8 · +12

Fastlane-compatible ZIPs

Output drops straight into deliver — correct folder structure, locale subdirs, and ordered filenames.

format=fastlane_zip

Localized screenshot sets

Pass a locale list and per-locale headline strings; get a complete set per language, RTL-aware, in one job.

40+ locales · RTL support

Device frames & templates

Wrap captures in accurate device bezels or branded layout templates — background, caption, and gravity all controllable.

frame=true · template=minimal-dark

Webhooks & async jobs

Large matrices run async. Poll the job or subscribe to a webhook — no holding a build agent open while frames render.

POST /v1/jobs · signed webhooks

BYOK AI optional

Bring your own model key to auto-draft localized captions and alt copy. Off by default — no model runs unless you enable it.

opt-in · bring_your_own_key

CI / CD

Screenshots that regenerate on every release.

Wire appscreenshotapi into the pipeline you already run. Captures go in on build; fresh, localized store assets come out — committed or uploaded automatically.

Built specifically for app store screenshot automation, Fastlane screenshots, and Google Play screenshot generation from CI.

app store screenshot API Fastlane screenshots Google Play screenshot automation CI screenshot generation

Yes. appscreenshotapi is an API-first app store screenshot generator. You POST source captures with the device sizes and locales you need to /v1/screenshots and receive a Fastlane-ready ZIP back — no manual screenshot-maker website in the loop. It's designed to run from GitHub Actions, Bitrise, Xcode Cloud, or any shell, including an AI coding agent's tool calls.

Request format=fastlane_zip and the output matches the folder structure deliver expects — locale subdirectories and ordered filenames. Call appscreenshotapi from a lane, point deliver at the extracted folder, and your localized screenshots upload to App Store Connect with no extra glue code.

It does. Add Android device targets such as pixel_8 or pixel_tablet and appscreenshotapi returns Play-store-correct dimensions alongside your iOS sizes in the same job. Pair it with your existing upload step or supply to push to the Play Console.

All current App Store Connect classes (6.7", 6.5", 5.5", iPad 13" and 12.9") and Google Play phone/tablet sizes, plus 40+ locales with RTL support. One source capture fans out across the full matrix — a 3-device × 3-locale request returns 54 assets in a single ZIP.

No. appscreenshotapi does not fabricate app UI. It frames, resizes, and localizes the real captures you upload. AI is strictly opt-in (BYOK) and only drafts caption copy when you enable it — there are no fake-magic claims and no model runs unless you ask for one.

Jobs run asynchronously. You get a job ID immediately, then either poll /v1/jobs/:id or receive a signed webhook when the ZIP is ready — so CI never blocks a build agent waiting on a large render matrix. Requests are idempotent and safe to retry.
