yunohost it’s basically an os that easily lets you selfhost, by having an extremely big amount of selfhosted services packaged with scripts that autonatically set everything up and all of that trough a clear and modern web interface.
Jitsi - Open-source and self-hosted video conference platform. You can even try it directly on their website.
IPFS - A distributed file sharing technology which is wonderful for file or site hosting (edit: wether it is uncensorable is open for debate)
Rust - A programming language and a powerful compiler that creates compiled memory-safe programs and can be used nearly everywhere
Fedora + KDE - A combination of a stable modern OS and a complete desktop environment
Wine - launch Windows programs on the latter

Bonus : AlternativeTo to find good open-source alternative software
Paperless-ngx that allows you to self host an easily browseable archive of your documents. Fully featured with OCR, ML-powered categorization and the works.
KDEConnect - I use it on Windows and android phone. Very nice when you get security codes or links on phone, want to send files or when I want to control audio|video and I watch from the couch.
in general: Fdroid nearly always has a more feature rich and performant alternative
OpenStreetmap as an alternative to the closed source maps.
OrganicMaps or OsmAnd to navigate and StreetComplete or EveryDoor to improve it.
KepassXC for PC and KeepassDX for Android phones.
I personally would recommend it over Bitwarden since with Bitwarden you NEED internet to access your passwords, and even if is open source, i canmot trust it, security breaches can happen in any time, having your vault locally stored helps a lot.
There are more but i can’t Remember them right now.
