It comes in both community & commericial editions (which can be self-hosted).

There is also a U.S. -based gratis instance at https://gitlab.com/users/ ( terms apply ).   How to pin a GitLab repository with Nix + Nixtamal  Let’s show the way using the highlight repository.

When you write this, you will substitute the owner & project slugs.

In most cases, you will want to prefer fetching the archive (GitLab supports bzip ) over the Git input kind. git ls-remote is preferred by us for being more generic.  Latest revision  // manifest.kdl inputs  {  highlight  {  archive  {  url  "https://gitlab.com/saalen/highlight/-/archive/{{fresh-value}}/highlight-{{fresh-value}}.tar.bz2"   }   }  fresh-cmd  {  $  git  ls-remote  --branches  master  "https://gitlab.com/saalen/highlight.git"  |  cut  -f1   }  }  Latest stable tagged version  // manifest.kdl inputs  {  highlight  {  archive  {  url  "https://gitlab.com/saalen/highlight/-/archive/{{fresh-value}}/highlight-{{fresh-value}}.tar.bz2"   }   }   // Looks for tag starting with v[0-9] since some tags didn’t take on  // this version structure but also must end in [0-9] to remove alpha,  // beta, release tags fresh-cmd  {  $  git  ls-remote  --tags  --sort= v:refname  "https://gitlab.com/saalen/highlight.git"  |  grep  -E  "'refs/tags/v([0-9]+ \\ .)+[0-9]+$'"  |  tail  -n1  |  sed  "'s|.*refs/tags/||'"   }  }       Site made with Nix ( dep management), Nickel ( config ), Soupault ( SSG ), Docutils ( rST rendering), mandoc (manpage conversion), & sugilite256 (color scheme).  © 2025–2026 toastal .
