# `nix-versions` - All versions of nixpkgs at your fingerprints.
2

-
`nix-versions` is a CLI tool that can help you [find the nixpkgs revision for historical versions of a package](https://nix-versions.alwaysdata.net/getting-started/listing-versions.html).
4

It does so by integrating the following services available to the nix ecosystem:
6
···
16
17
It also features [version constraint](https://github.com/Masterminds/semver?tab=readme-ov-file#hyphen-range-comparisons) filters, allowing you to restrict packages to a known set of compatible/stable versions that work with you.
18
19
-
When used in conjuction with `nix shell` and `direnv`, `nix-versions`, it can also double as a plain-text [development shell and tools version manager with automatic environment loading](https://nix-versions.alwaysdata.net/tools-version-manager.html) targeting people new to nix, but familiar with tools like npm, rvm, asdf, mise.
20
21
-
Our website provides a flakes generator for version-pinned packages. You can use these generated flakes as inputs on your own flakes, [allowing version constrained package updates](https://nix-versions.alwaysdata.net/flake-generator.html).
