If you need something simple Gitea, if you want CI/CD pipelines, SAST testing, PM, Gitlab-CE.

I use Gitlab-CE for work and personal now.

I've used Dokuwiki in the past, but at the end of last year, I swapped everything to Notion. I have everything from SOP, licenses, Hardware DBs, and Network DBs stored in one place.

For creds, I store these separately in Bitwarden.
