It uses a declarative KDL manifest file to manage inputs, supports VCS systems like Darcs and Pijul not available in Nix builtins, allows custom hash algorithms including BLAKE3, and enables user-defined freshness checks. The tool separates manifest and lockfile duties, works alongside other pinning tools, and leverages Nixpkgs fetchers for feature-rich input management. ## Full article daily.dev links to this article rather than hosting it.
