Plex.tv It’s a free multimedia server that you can install on your computer and start streaming your own video & music to yourself or your family and friends when you share your server. I paid for the Lifetime license because it’s worth it. I own a 36tb server at home and I shared my server to about 20 people.

Envy and jellyfish are other open-source solution that are also great to use.

Plex along with Plexamp

It’s been more than 25 years of accumulating mp3, editing and cleaning my libraries, upgrading to flac, etc. Now going strong at around 600gb of music.

It might be overkill and some sysadmin don’t like using them but Ubiquity with their Unifi model is all I’m using at home. USG as my router/firewall, 24-port 500w PoE switch, unifi cloud key for interface, and an AP-AC-Pro for WiFi access. The access point is enough to cover all my house and even my backyard.
