DreamHost★★★★☆Rock solid web hosting with managed VPS and good support. Hosting this page right now. Cloud computing has been less stable in my experience.
Floccus Bookmarks Sync★★★★★Very flexible, syncs across many different desktop browsers and mobile devices, and for privacy it can run on your own server or encrypted on another cloud service.
GoToSocial★★★★☆A lightweight Fediverse server, with a clean web interface for viewing public posts. Compatible with Mastodon apps and interacts with other ActivityPub platforms.
Jellyfin★★★★★Great for playing music across my local network, doesn't phone home to a cloud or try to upsell subscriptions.
KeePass Password Managers★★★★★KeePassXC, its browser extension, and KeePass2Android are a nice, clean set of apps to manage your passwords on your OWN desktop and mobile devices, auto-fill websites and apps, and sync over your own server or cloud provider.
Linode★★★★★Flexible, inexpensive cloud hosting with a variety of Linux options. Rock solid so far!
Nextcloud News★★★★★Simple web-based news reader for Nextcloud, easy to install and syncs with mobile clients.
Nextcloud Notes★★★★★Simpler than Google Keep, more private, with human-readable data that syncs quickly and cleanly with your devices.
OpenTasks★★★★★Simple to-do list that works great with a Nextcloud server.
Plex★★★☆☆It does let you stream your local media library, but it insists on connecting to a cloud account and pushes you to buy a subscription, even if you're not using its remote services.
