Most Electron/desktop apps rely on GitHub Releases + Squirrel or SaaS for updates. I built FaynoSync, an open-source self-hosted API server for managing app versions and updates.

It supports multiple channels, platforms, architectures, private apps with auth, multiple S3 providers, flexible user management, telemetry, and critical updates.

My question:

Would you self-host an updater instead of using GitHub/SaaS?

Which features are essential?

Or is the problem already solved well enough?
