Design and localize screenshots, edit metadata in every language, push builds through TestFlight and submit for review. One window, no browser tabs.
Soonon the Mac App StoreFree to download. Pro is optional. Your key never leaves your Keychain.
Screenshots, metadata, TestFlight, submit. Each step is a tab, and the whole thing is one window.
1Screenshots
Drop in simulator captures, pick a layout and a device frame, write the caption for each locale. Slipway renders an exact App Store PNG for every device and uploads the set.
2Metadata and localization
Name, subtitle, keywords, description and What’s New for every language you ship, with character limits flagged before Apple sees them and a diff against the live listing.
3TestFlight
See each build’s state and expiry, hand it to a group, write What to Test and read tester feedback, all on one page.
4Submit
Precheck sorts problems into blockers and warnings. Attach the build, write notes for the reviewer, choose how the release goes out and submit from the same window.
5After launch
An ASO score computed on your Mac, keyword ideas from your own AI key, a store preview, and review replies drafted where you read them.
“Localize the What’s New into every language, attach build 42 and submit as a phased release.”

Yes. Slipway only uses Apple’s official App Store Connect API, with a key you create and can revoke at any time. There’s no scraping, no browser automation and no Apple ID password. Actions that can’t be undone, like releasing a version or expiring a build, ask you to confirm first.
From your Mac to Apple, and nowhere else. There’s no Slipway server, no account and no telemetry. Your API key lives in the macOS Keychain. If you turn on AI features, listing text goes directly to the provider you picked, using your own key.
A Team Key with the App Manager role, created under Users and Access, Integrations in App Store Connect. That covers metadata, screenshots, builds, TestFlight and submission. Team pages such as Users and Access, sales reports and pricing need a key with a broader role, such as Admin.
macOS 15 Sequoia and later, on Apple silicon and Intel Macs.
Any model your provider offers. Slipway fetches the model list from Anthropic, OpenAI, Google Gemini, xAI Grok, Ollama or any OpenAI-compatible endpoint, and you choose. With Ollama the AI features run on your Mac and work offline. AI is optional; nothing in the release flow needs it.
Helm is a mature App Store Connect client with an iPhone app and a command-line tool, and it’s worth a look. Slipway is built around the screenshot pipeline: design once, caption per locale, render every device size and upload the whole set, with metadata localization next to it. It runs only on your Mac, with no account and no server, and its AI features work with whichever provider and key you already have.
Slipway is coming to the Mac App Store. It is free to download; Pro is an optional in-app purchase.
