Krops vs NixOps feature-crunch

Krops

Pro

• very lightweight, it is just a lib
• precise versioning of NixPkgs you can specify nixpkgs commit/branch/tag you want to roll out on which machine. ( your server runs 18.03 and your desktop unstable )
• native password-store support.
• You can rerun you deployment on the machine itself using nixos-rebuild switch.
• No Database needed.
• Build/Download happens on the target system.

Con

• you need to have git installed (yeah not a real con)
• not as good documented as NixOps.
• works only on NixOs (?)

NixOps

Pro

• well documented

Con

• quite heavy
• host channel is roled out on servers ( not possible to have different channels on different servers )
• can't just run nixos-rebuild switch on the target machines.
• you need a database (for some reason).
• Build/Download happens on deploying machine, which is bad when you have a bad internet-connection.
