Marnix is your AI CTO. Describe an app out loud and our build cloud writes it for you — code, design, and a live URL, streamed back to your phone in real time. No syntax. No setup. No second laptop. Just talk it through. ——————————— HOW IT WORKS ——————————— 1. Open a huddle on your phone and talk it through — or type a prompt. 2. Your idea is sent securely to our build cloud, where our AI plans your app, writes the code, and starts shipping it. 3. The result streams back to your phone live as it's built. Iterate by voice or text — "add Stripe", "darker header" — until it's exactly right. 4. Publish it to a real, live URL. Marnix requires an internet connection — all generation happens on our servers, not on your device. ——————————— WHAT YOU CAN BUILD ——————————— Landing pages. Dashboards. Internal tools. Travel planners. Habit trackers. Pricing pages. Investor briefs. CRM screens. Booking flows. Side-project ideas you've been sitting on for months. If you can describe it, Marnix can build it. ——————————— FEATURES ——————————— • Voice huddles — talk through an idea in real time, Marnix talks back • Live preview streaming — watch the build progress on your phone as our cloud writes it • Iterate by voice — "make the header darker, add a search bar, connect Stripe" • 10 voice languages — English, Dutch, Spanish, French, German, Italian, Portuguese, Chinese, Japanese, Korean • Connect Stripe, Supabase, GitHub and 98+ services without leaving the huddle • Publish to yourname.marnix.ai instantly — free, with HTTPS • Bring your own custom domain • Big-screen mode — beam any project to your laptop or TV by scanning a QR code • 10 hand-painted city themes — Tokyo, Paris, Amsterdam, Seoul, New York, San Francisco, London, Silicon Valley, Spaceport, and more • Matching app icons for every theme • Live Activities + Dynamic Island — track your build from the Lock Screen while you do other things • Native iPad support • Dark mode throughout ——————————— START FREE ——————————— Every new account gets 300 free credits — enough to build, iterate, and ship a real app before deciding whether to upgrade. ——————————— MARNIX PRO ——————————— For makers who ship daily. Higher credit limits, custom domains, priority cloud generation, advanced models. ——————————— MARNIX BUSINESS ——————————— For founders and small teams. Higher iteration limits, fastest cloud generations, team workspace, priority support. ——————————— SUBSCRIPTION TERMS ——————————— • Marnix Pro and Marnix Business are auto-renewing subscriptions offered monthly or annually. • Payment is charged to your Apple ID at confirmation of purchase. • Your subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. • Manage or cancel anytime in Settings → [Your Name] → Subscriptions. • Any unused portion of a free trial is forfeited when you purchase a subscription. ——————————— PRIVACY ——————————— Marnix processes your prompts and project data on our secure servers in order to build your app. We don't train AI models on your work, and you can delete your projects at any time.

Deploy Studio
Read full descriptionHide full description
Deploy Studio is a client for the App Store Connect API that can actually ship a release from a phone: pick a build, write release notes, answer export compliance, and submit the version — with its in-app purchases — for App Review. PREPARE AND SUBMIT A RELEASE • A release checklist that leads with what needs you and folds away what is already done • Plain language instead of Apple's error codes: "add at least one screenshot", not a status enum • Build, export compliance, What's New, screenshots, store listing, app information, age rating, price, App Review information, release option, and in-app purchases riding along • Submit for review when everything is green KNOW WHAT NEEDS YOU • One Today screen across every app: rejections, unanswered reviews, builds waiting on beta review, certificates about to expire • Notifications when a version is approved or rejected, checked in the background on your device • A Home Screen widget showing what the app last saw WHEN SOMETHING BREAKS • Crash reports from TestFlight testers with the full symbolicated log, copyable in one tap • Xcode Cloud runs broken into steps, with the errors from the step that failed • Start an Xcode Cloud build from anywhere • Signing that tells you which certificate expired before Xcode refuses to archive • API Status: whether App Store Connect is answering, and whether a failure is Apple's or your key's THE NUMBERS, HONESTLY • Downloads that exclude updates — counting updates as downloads overstates them several times over • Proceeds listed per currency rather than summed, because a total across storefronts is a number in no currency • Ratings and reviews, with replies YOUR KEY STAYS ON YOUR DEVICE Deploy Studio has no account and no server of its own. Your App Store Connect API key is stored in the device Keychain, never synced to iCloud, and used only to sign requests to api.appstoreconnect.apple.com. Tokens are minted on device and last twenty minutes. TRY IT WITHOUT A KEY Tap "Look Around First" on the first screen to explore every feature against sample data. Nothing is sent anywhere in that mode. Deploy Studio is free, with ads. A one-off Deploy Pro purchase removes them for good — no subscription, and every feature stays free either way. Deploy Studio is an independent app and is not affiliated with or endorsed by Apple Inc.

Verdict
The clearest difference is ads: Marnix at none against Deploy Studio's shown. Deploy Studio's advantage is update cadence (every 10 days vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
