Any questions left?
Onside is an official, iOS alternative app store focused on the EU and Japan. We offer three main advantages: greater choice through more flexible content guidelines, higher revenue for you with our low 8-10% commission rates, and a faster path to publishing via Apple's streamlined Notarization process ↗
We support a wider variety of app categories. If your app is legal in the EU and Japan, it's likely welcome on Onside. This includes apps in categories that may have limited distribution elsewhere, such as those related to Crypto, some Gaming, and legal, age-gated Adult content
Yes. Onside supports both native and non-native apps, including PWAs and web applications. You can easily wrap your web app into a native-like experience using our SDK and distribute it through Onside
Absolutely. Onside is built to give developers more freedom. You can publish apps that were never submitted to the App Store, as long as they comply with EU and Japan regulations and Onside’s safety and legality standards
Yes, absolutely! Our "Smart Synchronization" feature is designed for this. You can connect your App Store account to seamlessly sync your existing app builds and metadata, making it very easy to manage your presence on both platforms
Yes. An Apple Developer account is required. We use a secure integration with App Store Connect to sync your app builds and to process your app through Apple's Notarization service, which is a mandatory security step
No. Apple permits alternative distribution methods in the EU under the Digital Markets Act and under the Mobile Software Competition Act (MSCA) in Japan. Onside operates fully within those rules and uses notarized builds for added security and compliance.
Nothing changes. Your app remains live on the App Store, and you can distribute the same or modified builds through Onside. Our Smart Synchronization feature keeps both platforms aligned without affecting your App Store listing
It's a straightforward, multi-step process:
Register & Connect: Create your Onside Developer account and securely link your existing Apple Developer account to sync your app builds.
Configure: Set up your app's metadata (description, screenshots, etc.), pricing, and select the regions where it will be available.
Publish: Submit your app for a quick review. Once approved, it will be live in the Onside Store.
For a full walkthrough, please see our Developer Documentation ↗
We request only the permissions required to sync your app builds, metadata, and notarization status through App Store Connect. We do not access any personal data, analytics, or unrelated developer resources
Yes. In your Developer Console, you can choose what to sync — builds, metadata, or both. You’re always in control of when and what gets updated between Onside and the App Store
You can disconnect your App Store integration or delete your Onside Developer account anytime.
Your App Store presence remains untouched, and you can continue distributing your apps there as before
Onside follows strict security and privacy standards, including PCI DSS certification for payment processing and encrypted data storage. All integrations with App Store Connect are secured via OAuth and verified endpoints
We comply with EU Digital Markets Act (DMA) requirements and other relevant regional laws. Our legal and compliance team continuously reviews policies to ensure both developers and users remain protected
Our developer-friendly commission ranges from 8% to 10%. The final rate is discussed individually and depends on factors like your company size and app category. Our goal is to ensure you keep more of your earnings
All revenue models run through the Onside Payment SDK:
- Paid apps — one-time upfront price
- In-app purchases — sell digital content and features
- Subscriptions — recurring access with integrated management
Integration typically takes under 30 minutes.
The SDK is lightweight, StoreKit-like, and compatible with Web, React Native (Expo), and fully native iOS apps
Yes. You can integrate your existing provider or gateway as long as it complies with EU/Japan payment regulations
You can manage your financial information and request payouts directly from the Onside Developer Console. We offer flexible options, including scheduled (e.g., monthly) or manual on-demand payouts to your bank account
Apps are featured and searchable in the Onside Store. You can also share direct links, integrate install CTAs into your marketing, and benefit from Onside’s promotional featuring and category highlights
Yes. You control your app’s page design — description, visuals, pricing, and updates
We offer custom Install Landing Pages development, custom promo campaigns, and tailored partnerships for selected apps. Developers may also receive reduced commission rates as part of special promotions
Your Onside Developer Console provides real-time insights — installs, conversions, revenue, and attribution data. We can send data to Google Ads, Meta Ads and other platforms to Improve Conversions and Lower CPA.
