Here are a few I like:
- Jellyfin - a media server software that allows you to organize and stream your personal media collection.
- NextCloud - a self-hosted file sync and sharing platform. Not as good as Google Drive (of course), but it can do the job.
- Bitwarden (with a Rust-written alternative named vaultwarden) - a password manager for storing and autofilling login credentials.
- Matrix - an open network for secure, decentralized communication. WhatsApp, but in the Fediverse.
- PiHole - a DNS sinkhole that blocks ads and other unwanted content.
- Mycroft - an open-source voice assistant. You can make your own Google Home with it.
- OctoPrint - web interface that allows you to control 3D printers. Pretty handy if you have one!
- Gitea - a lightweight self-hostable GitHub
- Home Assistant - an open-source home automation platform. Can integrate a lot of other things in your house, including some of the things I mentioned above.
- The X-arr initiative - a collection of tools for managing and organizing media libraries. Pretty good if you deploy your own media server:
- Sonarr - Select TV shows and it will automatically download episodes for you.
- Radarr -> movies
- Lidarr -> music
I’d love to see a poll option :)
