Create free and paid content your app can fetch safely through a project API key.
Backend cloud for indie iOS apps
Ship the app. Skip the backend.
Kernbahn gives solo iOS developers the hosted content, entitlement checks, webhook traces, and Swift SDK they usually have to stitch together by hand.

Product
Everything small apps need after launch.
Start with hosted content and entitlement checks, then add project logs, API keys, and clean admin workflows as your app grows.
Receive webhook events and expose simple entitlement checks to your Swift code.
Debug requests, webhook deliveries, and content changes without spelunking through infrastructure.
Use a small async/await client that feels native in app code and boring in production.
Workflow
A dashboard for shipping, not babysitting servers.
Kernbahn keeps the operational surface familiar: projects, content, environments, release state, and recent activity, all in one tidy place.
