Push Notification Server Hosting on Offshore VPS
Push notifications powered by Firebase or APNs route through Google and Apple servers, exposing your user data and notification content to third parties. A self-hosted push notification server on AnubizHost offshore VPS keeps notification payloads and subscriber lists entirely under your control, with no third-party data processing agreement required.

Self-Hosted Push Notification Options
The leading open-source push notification servers each take a different approach. Ntfy is a topic-based pub/sub HTTP push server with web, Android, and iOS clients, a REST API, and optional authentication. Subscribers poll or maintain a long-HTTP connection; the server pushes to connected clients immediately. Gotify is a self-hosted push notification service with a web interface, a REST API, and Android app. For mobile apps specifically, Unified Push provides a decentralized alternative to FCM/APNs where the app connects to a user-chosen push server rather than Google's infrastructure. All three install on a single VPS via Docker or native packages and consume minimal resources - Ntfy with 1,000 active subscribers runs comfortably on 512 MB RAM.
Integrating with Mobile Apps and Web Clients
Integrating a self-hosted push server into a mobile app requires using the provider's SDK instead of (or alongside) FCM. The UnifiedPush ecosystem has distributor apps for Android (Ntfy app, Gotify UP) that handle the connection to the push server and deliver notifications to apps registered as UP consumers. For web push (browser notifications), the Web Push protocol uses VAPID keys - generate a key pair with web-push generate-vapid-keys, configure your server, and subscribe users from the browser's push API. Ntfy supports Web Push natively. AnubizHost VPS plans with open TCP 443 and WebSocket support (no additional configuration required) handle all of these protocols without firewall modifications.
Privacy and Regulatory Benefits of Self-Hosted Push
FCM routes every notification payload through Google's servers. For applications handling medical data, financial alerts, legal communications, or private organization news, this creates a GDPR data-processing relationship that requires a Data Processing Agreement with Google. Self-hosting eliminates that relationship entirely. Notification payloads travel directly from your application backend to your Ntfy or Gotify instance, then to the subscriber's device - no intermediary reads the content. On AnubizHost, the push server database (subscriber tokens, notification history) sits on your VPS disk in a jurisdiction you chose. Pay with cryptocurrency and your push infrastructure leaves no trace in any commercial cloud provider's billing records.
