Alternative à ButterKit : deux apps Mac natives

En bref : ButterKit and Screenshot Bro are both native Mac apps for App Store screenshots, and the choice usually comes down to three things: ButterKit needs macOS 26 or later and Screenshot Bro runs on macOS 15 and on iPad and iPhone; ButterKit reaches all 50 App Store languages only with your own AI provider key, while Screenshot Bro ships 81 language presets that translate on-device; and Screenshot Bro uploads to Google Play, which ButterKit does not.

ButterKit is a native macOS app for App Store screenshots and metadata, built by a solo developer in California and shipped roughly two or three times a month since September 2025. Of everything in this category it is the closest to Screenshot Bro: both are native Mac apps rather than browser tools, both keep project files on your disk with no account, both upload to App Store Connect, and both expose an MCP server so an AI agent can drive them. This page is for people searching for a ButterKit alternative — and the honest answer is that the two overlap a great deal, so the differences that remain are the whole decision.

Competitor details below were checked against ButterKit's own site, documentation and pricing page in August 2026; pricing and features change, so verify there before deciding.

What ButterKit Does Well

Several of these are things Screenshot Bro does not do at all, so they are worth stating plainly rather than glossing over.

• It captures from the Xcode Simulator itself. A floating capture tool follows the active Simulator window, and it reads the available localizations out of your Xcode String Catalog so you can switch language and re-capture. Screenshot Bro has no shipping equivalent — you bring it screenshots you have already taken.
• The 3D is real 3D. Devices are rendered live in Metal and can be rotated and angled freely, and a single device can overflow across several artboards. Screenshot Bro's frames are flat images apart from two fixed 3D iPhone models.
• It covers Apple Watch and Apple TV sizes. ButterKit lists watchOS and tvOS among its supported platforms. Screenshot Bro has an Apple Watch Ultra 3 frame but no Watch, TV or Vision Pro size preset, so if your listing needs those, this is a real gap on our side.
• It translates the listing metadata, not just the images. Description, keywords, subtitle and what's-new text go through the same translation step as the screenshot copy, with custom instructions for brand voice and do-not-translate terms, and delta translation so only changed strings get re-sent.
• It publishes its price. $99 one-time, listed down from $149, good for five Macs, with a 14-day money-back guarantee and a discount for students, teachers, veterans and first responders. There is an optional Supporter subscription, but you are not required to rent the app.
• You can install it however you like. Direct .dmg, the Mac App Store, or brew install --cask butterkit.

Why People Look for an Alternative

• They are not on macOS 26. This is the most common reason and the hardest to work around.
• They ship to Google Play and want to upload there too.
• They do not want to buy and manage an AI provider key to get past 19 languages.
• They want to ship a small listing without paying, and a watermark rules that out.
• They want to work on an iPad or iPhone, not only a Mac.

ButterKit vs Screenshot Bro

The Three Differences That Actually Decide It

1. Which macOS you are on

ButterKit requires macOS 26 (Tahoe) or later — stated in its own system requirements, and enforced by its Homebrew cask. That is a recent OS, and a developer who keeps a machine one or two versions back for build stability simply cannot run it. Screenshot Bro runs on macOS 15 or later, and also runs on iPad and iPhone from the same purchase. If you are on Tahoe, this difference is irrelevant. If you are not, it ends the comparison.

2. What translation costs you

Both apps translate on-device using Apple's Translation framework, and both are honest that this covers a limited set of languages. ButterKit's documentation puts its on-device coverage at 19 languages; to reach all 50 App Store languages you connect a cloud model with your own API key — OpenAI, Gemini, Claude, OpenRouter, or a local model through an OpenAI-compatible endpoint. Screenshot Bro ships 81 language presets plus custom locale codes, with no key to buy and no per-token cost, but the automatic translation only covers what Apple's framework supports; the rest you type or paste.

These are genuinely different trades, not one being better. ButterKit gives you machine translation everywhere at your own metered expense and lets you steer it with custom instructions. Screenshot Bro gives you more locale slots for free and leaves the long tail to you or your translator. If you already pay for an AI API and want the machine to write all 50, the ButterKit model is the better fit — and this page should not talk you out of it.

3. Whether Android is in scope

ButterKit has Google Play size presets and a Pixel 10 Pro device model, so you can design Play assets in it and export them as files. What it does not have is a Google Play upload — its own roadmap lists "Google Play Store support" under Exploring. Screenshot Bro uploads to Google Play through the Play Developer API with a service account, staged as a Play edit you confirm, and that is on the free tier along with App Store Connect upload. If you ship to one store, this does not matter. If you ship to both, it is the difference between one tool and two.

About the Free Tiers

It is worth being precise here, because ButterKit's free tier is more generous than ours in the dimension most people check first. ButterKit gives you unlimited projects and artboards and watermarks every export. Screenshot Bro gives you one project, three rows and five templates per row, and what comes out is watermark-free and shippable, with both store uploads included.

So the question is not which free tier is bigger — it is which limit you hit first. If you want to explore a large design across many artboards before committing, ButterKit's shape is friendlier. If you have one small app and want to ship its listing today without paying anyone, Screenshot Bro's shape is the one that gets you there. One more wrinkle worth checking yourself: ButterKit's pricing page lists "All 50 App Store languages" and "Upload to App Store Connect" under Free, while its Pro documentation scopes cloud translation and App Store Connect management to Pro. Those two pages do not quite agree, so confirm in the app which applies to you.

Who Should Pick Which

Choose ButterKit if you are on macOS 26, you want screenshots captured straight out of the Xcode Simulator, you want rotatable 3D device renders, you need Apple Watch or Apple TV sizes, you want your listing metadata translated alongside the images, or you would rather bring your own AI key and translate everything by machine. It is a well-built, actively developed app and the one-time price is clearly stated.

Choose Screenshot Bro if you are not yet on macOS 26, if you want to work on iPad or iPhone as well as Mac, if you ship to Google Play and want to upload there from the same window, if you want 81 locale presets without buying an AI API key, if you need watermark-free exports before you pay anything, or if you want your project files as plain, publicly documented JSON.
