Ask HN: What self-hosted apps do you use daily?

I've been running a homelab for many years now and tried out many open source projects. A small percentage turn out to be real gems, but I use these almost every single day:

Shlink: URL shortener/redirects, alternative to Bitly

Vaultwarden: open source Bitwarden server

Dokploy: PaaS, alternative to Vercel / Netlify

Umami: gdpr-compliant web analytics

Immich: photo management

Papra: document archiving with OCR

Navidrome: personal music streaming

I'm super curious to hear about the apps you can't live without!
