Kukuroo deploys self-hosted web push notifications as a Cloudflare Worker with iOS 18.4 support
↗
Kukuroo is a self-hosted push notification service that runs entirely as a Cloudflare Worker, using iOS 18.4's declarative web push to deliver lock-screen notifications without a native app or third-party intermediary.
Engineers who need alerts from their own systems can now get push to an iPhone lock screen without building a native app, paying an App Store developer fee, or routing through a vendor's dashboard. The tradeoff is narrow platform support: it only runs on Cloudflare Workers and only delivers to Safari on iOS 18.4+ or macOS Safari 18.5+, with other browsers explicitly turned away.

Kukuroo runs as a single Cloudflare Worker with a KV namespace, requiring no server to maintain, renew, or restart.
It delivers notifications to iOS 18.4+ devices via Safari Home Screen web apps, bypassing the App Store and the $99/year developer fee.
The free Cloudflare plan supports 50 devices per send and 100,000 requests daily, with a $5/month tier raising those limits to 10,000 devices and 10 million requests.
