Comparison
Screenshotify vs Fastlane — generator vs source-screenshot capture
TL;DR. Fastlane is an open-source Ruby toolchain. `fastlane snapshot` captures raw iOS-simulator screenshots from UI tests; `frameit` overlays device frames + your own captions. It's free, scriptable, CI-friendly, and ideal if you want screenshots straight from your app's actual state — but you write Swift UI tests, maintain a Snapfile, and the visual result is plain raw simulator captures with optional caption overlays. Screenshotify is a browser editor for designed marketing screenshots: drop a phone screenshot, place it in a device frame, write captions, translate to 39 languages, export. Different categories — Fastlane = capture pipeline, Screenshotify = design tool.
Feature-by-feature
| Feature | Screenshotify | Fastlane |
|---|---|---|
| Tool category | Browser design tool for marketing screenshots | CLI capture pipeline + frame overlay |
| Pricing | Free to design · €19.99/mo to export | Free (open-source MIT) |
| Skill required | Anyone who can drop a PNG and write a headline | iOS dev: Swift UI tests + Ruby Snapfile + Xcode CI |
| Source of screenshots | You drop PNG/screenshot files from your phone or simulator | Auto-captured from your app's UI tests at the screen-state you scripted |
| Localization workflow | One click translates captions across all 39 App Store locales | Run snapshot per locale (loop over devices.locales); captions are part of overlay images you ship per locale |
| Marketing overlays / branded backgrounds | Native: gradients, frames, spanning layers, AI translation, JSON save/load | Possible via frameit, but the visual output is raw simulator + caption strip — not designed marketing carousels |
| CI/CD integration | Manual export (API on the 2026 roadmap) | First-class: fastlane lane in your CI pipeline, regenerate on every release |
| Multi-panel carousels with spanning layers | Yes — Apple's 10-panel max with shared backgrounds | Out of scope — Fastlane produces one screenshot per state, not designed multi-panel stories |
| Phone-to-desktop pairing | WebRTC QR — drop screenshots from real device | Not applicable — captures from simulator, not real phone |
Why switch to Screenshotify
- You ship marketing screenshots, not raw UI-test captures. Apple's top-100 carousels are designed images, not screenshots of your app screen-by-screen.
- You don't want to write and maintain Swift UI tests just to produce App Store images.
- You need fast iteration: a designer or PM can tweak a caption in 10 seconds, not wait for a Swift test suite to recompile.
When Fastlane is the better choice
We don't claim to be the right tool for everyone. Here's when Fastlane actually wins:
- You want screenshots that always reflect the app's current real state — if a button moves, your screenshots break in CI. That's exactly what Fastlane gives you.
- Your team is iOS-only with a strong CI culture, the Swift+Ruby cost is already paid, and "designed marketing screenshots" isn't a requirement.
- You need batch-generation of raw localized screenshots as input for a separate design tool — use Fastlane to capture, then bring the PNGs into Screenshotify to design with them. Both tools can coexist.
