Kukuroo offers self-hosted web push notifications via Cloudflare Workers for iOS

Self-Hosted Web Push Solution

Kukuroo introduced a new method for self-hosting web push notifications. This system operates entirely within a single Cloudflare Worker and a KV namespace, eliminating the need for dedicated servers or complex infrastructure management. The solution is designed to provide developers with full ownership and control over their push notification endpoints.

iOS Compatibility

A key feature of Kukuroo is its compatibility with iOS 18.4 and later versions. This allows web applications added to the Home Screen on iOS devices to receive native push notifications directly on the lock screen. This bypasses the traditional requirement of developing and distributing a native iOS application solely for notification purposes.

Data Control and Security

The architecture ensures that all encryption keys and notification payloads remain within the user's Cloudflare Worker. This approach prevents third-party services from accessing sensitive alert data, enhancing privacy and security for both developers and end-users. Notifications are encrypted to the device, ensuring that only the intended recipient can view the content.

Simplified Integration and Deployment

Kukuroo emphasizes ease of use with a one-click integration process. A single command handles the deployment of the Worker, key generation, installation, and storage provisioning. The system can also mount into an existing Cloudflare Worker router, allowing devices to enroll on the user's current hostname.

Prerequisites and Scalability

The solution specifically requires Cloudflare Workers, Safari (due to its support for Declarative Web Push), and iOS 18.4+ (with the web page added to the Home Screen). A Cloudflare account is necessary, with the free tier supporting personal setups up to 50 devices per send and 100,000 requests daily. Paid plans offer increased capacity for larger-scale deployments.
