ButterKitvs.AppScreens
After designing thousands of App Store screenshots with dozens of tools, a design engineer answers the question: which gives you better screenshots for less?
Quick answer: ButterKit is the better pick for Apple-only developers who want real-time 3D mockups, Xcode Simulator capture, Fastlane/MCP/AI automation, and offline-first design. AppScreens is the better pick if you ship to both the App Store and Google Play and prefer a browser-based tool with 500+ templates.
What's the quick summary?
AppScreens is a web-based screenshot generator with 500+ templates, cross-platform store support (App Store, Google Play, and more), and responsive layouts that adapt one design across devices.
ButterKit is a macOS app with 3D devices, Xcode Simulator capture, MCP and automation support, auto-translation across all 50 App Store languages, and direct publishing to App Store Connect.
Because ButterKit runs entirely on your Mac, it costs $39/year or a one-time $79 purchase vs. AppScreens’ $90+/year subscription.
What are the key takeaways?
- AppScreens is strong for multi-store reach. If you ship to both the App Store and Google Play, AppScreens lets you upload to both.
- ButterKit wins on developer integration. Real-time 3D mockups, Xcode Simulator capture, Fastlane integration, AI/MCP automation, and direct App Store Connect upload are all included out of the box.
- Pricing favors ButterKit. A one-time $79 one-time purchase or $39/year vs. AppScreens' $25/month or $90/year subscription.
- Both support localization, but differently. ButterKit translates to all 50 App Store languages using frontier AI models. AppScreens supports 80+ languages with RTL layout adaptation.
- ButterKit supports AI agent automation via MCP. Integrate with Claude Code, Cursor, or Codex to automate screenshot generation (e.g. "Claude, add Spanish localization to my ButterKit project, make all text bolder, and then upload all screenshots and metadata to App Store Connect") See how
Below, I break down what to look for in a screenshot tool, compare both tools feature by feature, and answer the most common questions developers ask when choosing between the two.
What should you look for in a screenshot tool?
Six things I highly recommend in a screenshot tool.
Polished, effective designs
The most important part: it should be easy to create beautiful, effective screenshots that sell your product.
Built-in localization
Auto-translate screenshots and metadata to all 50 App Store languages using frontier AI models while retaining design constraints.
Capture from Xcode Simulator & Fastlane
Should capture right from Xcode Simulator or allow linking an entire folder of screenshots (e.g. fastlane).
3D device mockups
Photorealistic device frames make your app feel real and professional, and allow depth so you can show more context.
Automation & App Store Connect
MCP support and App Store Connect API to upload images and metadata straight to App Store Connect, without manual browser editing.
Developer-friendly pricing
One-time purchase or affordable flat plans. No per-seat subscriptions that grow with your team.
How did I test these tools?
I created real App Store screenshots using both ButterKit and AppScreens. I evaluated design quality, template variety, 3D rendering capability, localization across languages, export reliability, App Store Connect upload capability, and total time from raw screenshot to published listing. Pricing was compared as of May 2026.

App Store screenshot workflow
ButterKit
ButterKit was built by a design engineer specifically for App Store screenshots and localization, so it all happens in one workflow. Capture directly from Xcode Simulator, use professional templates, auto-translate caption text to all 50 App Store languages, and batch export or upload directly to App Store Connect, all without leaving the app. One design change propagates across every language and device size automatically.
AppScreens
A browser-based screenshot builder with 500+ templates and responsive layouts. Upload your screenshots, pick a template, add text and backgrounds, then export or upload directly to App Store Connect and Google Play Console. Supports multiple app stores in one project, but there is no Xcode integration or automation pipeline.
3D device mockups
ButterKit
Buttery-smooth, real-time 3D rendering powered by Metal at up to 120fps on Apple Silicon. Photorealistic iPhone, iPad, Mac, Apple Watch, and Vision Pro models you can freely rotate, angle, and customize. Interactively, in real-time. Your screenshots are rendered inside the device, not composited on top.
AppScreens
AppScreens offers device frames in several styles (real, clay, 3D-style, outline), but these are 2D overlays rather than real-time rendered 3D models. You can't freely rotate or adjust the angle. Great for quick production with pre-made layouts, but less control over device perspective and lighting.
Xcode Simulator integration
ButterKit
Because ButterKit is a native Mac app, it connects directly to Xcode Simulator. Capture screenshots from any running simulator with one click. No manual screenshotting, no file management, no dragging images between apps. Update your code, capture fresh screenshots, and your designs update instantly.
AppScreens
No Xcode integration. You need to manually take screenshots from the Simulator (or a physical device), save them to your computer, then upload each one to the web app through your browser. Every time your UI changes, you repeat the entire process.
Localization & translation
ButterKit
Translating screenshot text blocks and App Store Connect metadata (app description, what's new, keywords, subtitle) to all 50 App Store languages is quick and easy with an intuitive interface that feels at-home on macOS. On-device translation (18 languages) is free with no subscription required. Cloud translation (e.g. with Claude, Codex etc) is available with Pro (bring your own API key). Update the original and every translation updates too. Each translation is customizable
AppScreens
AI-powered translation to 80+ languages. However, translation appears to be entirely unavailable withour a Pro subscription. Layouts automatically adapt when text expands, contracts, or flips direction. Switching between localizations can be challenging and requires many clicks. No App Store metadata translation.
Store support & platforms
ButterKit
ButterKit is purpose-built for the Apple ecosystem. It covers App Store screenshots and metadata for iPhone, iPad, Mac, Apple Watch, and Apple Vision Pro. If you only ship to the App Store, this focused approach means zero wasted UI or complexity for platforms you don't use.
AppScreens
AppScreens supports multiple stores: Apple App Store, Google Play, Microsoft Store, Amazon Appstore, Huawei AppGallery, and Chrome Web Store. If you ship to Android and iOS (or more), you can manage all store assets from one project. It also supports Custom Product Pages (CPP) and Product Page Optimization (PPO) variants.
Pricing & ownership model
ButterKit
- Free: Unlimited projects, templates, watermarked exports
- Pro: $79 one-time or $39/year
- One license, up to 5 machines.
AppScreens
- Free: Limited to 5 screenshots, 1 project, basic features
- Pro: $25/month or $90/year
- Account required for all plans.
App Store Connect & publishing
ButterKit
Connects directly to the App Store Connect API. Upload all your screenshots and translated app metadata (description, what's new, keywords) without ever opening a browser. Because ButterKit creates the screenshots, it already knows the correct sizes and locales, so there's zero manual file management.
AppScreens
One-click upload to both App Store Connect and Google Play Console. Handles every device size and localization in a single action. Also supports uploading Custom Product Page (CPP) and Product Page Optimization (PPO) variants, which is useful for A/B testing store listings.
Platform & performance
ButterKit
Native macOS app built with Swift and Metal. Works completely offline, requires no account, and delivers up to 120fps 3D rendering on Apple Silicon. Your data never leaves your machine. The trade-off: macOS only (15.6+).
AppScreens
Runs in any modern web browser on any operating system: Mac, Windows, Linux, ChromeOS. No download required. The trade-off: requires an internet connection, an account, and performance depends on your browser and connection speed.

Frequently asked questions
Common questions about ButterKit and AppScreens
Does AppScreens support real 3D device mockups?
AppScreens offers device frames in several styles (real, clay, 3D-style, outline), but these are 2D overlays rather than real-time rendered 3D models. You can’t freely rotate or adjust the angle yourself. ButterKit uses a real-time Metal-based 3D engine (up to 120fps on Apple Silicon) where you can interactively rotate, tilt, and customize photorealistic device models, similar to apps like Rotato.
What's the best AppScreens alternative?
For Apple developers, ButterKit is the strongest AppScreens alternative. It covers everything AppScreens does for the App Store (templates, localization, device frames, App Store Connect upload) and adds real-time 3D mockups, Xcode Simulator capture, Fastlane and folder-linking, and MCP automation support for AI agents. It also costs significantly less: $39/year or a one-time $79 vs. AppScreens’ $90+/year.
Which tool supports more app stores?
AppScreens supports six stores: Apple App Store, Google Play, Microsoft Store, Amazon Appstore, Huawei AppGallery, and Chrome Web Store. ButterKit focuses more on Apple platforms (iPhone, iPad, Mac, Apple Watch, Apple Vision Pro) with some Google Play presets. If you ship to multiple stores, AppScreens has broader coverage. If you ship primarily to the App Store, ButterKit offers deeper integration.
Is AppScreens free?
AppScreens has a free tier, but it limits you to 1 project, limited localization and basic features. Most production features (localization, App Store upload, 3D-style frames) require the Pro plan at $25/month or $90/year. ButterKit also includes a generous free plan. See ButterKit pricing
Can I use AppScreens offline?
No. AppScreens is a web-based tool that requires an internet connection and a registered account. ButterKit is a native macOS app that works completely offline with no account required.
Does ButterKit really offer a one-time purchase?
Yes. ButterKit Pro is available as a $79 one-time lifetime license, or $39/year if you prefer a subscription. Because ButterKit runs entirely on your Mac with no servers, cloud storage, or ongoing infrastructure costs, a one-time price is sustainable. AppScreens requires $25/month or $90/year with no lifetime option. View ButterKit pricing
Can I capture screenshots directly from Xcode Simulator or Fastlane?
ButterKit is the only tool in this comparison that captures directly from the Xcode Simulator (learn more) and can link to a Fastlane screenshots folder, so screenshots flow into your design without manual exporting. AppScreens requires you to capture screenshots yourself and then import them via drag-and-drop or bulk upload.
Do both tools upload to App Store Connect?
Yes. Both ButterKit and AppScreens upload finished screenshots to App Store Connect via the official API. AppScreens also uploads to Google Play Console and supports Custom Product Pages (CPP) and Product Page Optimization (PPO). ButterKit additionally uploads translated app metadata (description, what’s new, keywords) alongside the screenshots.
Is ButterKit reliable for production workflows?
Yes. ButterKit is used by thousands of developers worldwide and has been featured in iOS Dev Weekly. It has 4.7 stars on the Mac App Store as of May 2026. It uses a Metal-based 3D rendering engine running at up to 120fps, uploads reliably to App Store Connect via the official API, and is actively maintained with regular updates. It is built for teams who ship frequently, not just one-off screenshots.
Does ButterKit support AI agent automation?
Yes. ButterKit includes a built-in Model Context Protocol (MCP) server that lets AI coding agents like Claude Code, Cursor, and Codex automate screenshot generation, translation, and publishing. You can script entire workflows from capture to App Store Connect upload. AppScreens has no equivalent automation support.
Is ButterKit only for macOS?
ButterKit is a native macOS app. This is by design: running natively on macOS enables Metal-based 3D rendering, direct Xcode Simulator integration, Fastlane folder linking, and offline-first operation that web-based tools cannot provide. If you develop for Apple platforms, you already have a Mac, so this is rarely a limitation in practice. If you need cross-platform access, AppScreens works in any browser.
Can ButterKit handle Google Play screenshots?
Yes. ButterKit focuses on Apple platforms: iPhone, iPad, Mac, Apple Watch, and Apple Vision Pro. It also has Google Play Store presets. If you also publish to Google Play, AppScreens supports Android device frames and Play Store dimensions natively.
What are real users saying?
"ButterKit is, by far, the best app for this. It has sped up my workflow 100x."
"I've tried so many screenshot tools and they were all too complex. I understood how to use ButterKit in just 10 seconds."
"My conversion rates have improved substantially with ButterKit."
