NixOS Gitlab Runners are quite nice in this regard. Caching for "free" (cost of admission: learning Nix)

Finally found a reason to learn Nix, thank you!

It is a lot of learning - you have to both run gitlab-runner on NixOS _and_ Nixify your project to get caching.

If you climb the learning curve that far though - you'll be hooked.
