aqua is a declarative command-line interface version manager written in Go, developed by aquaproj, designed to streamline the installation and switching of multiple CLI tools across projects without manual intervention. By declaring required tools and their exact versions in a simple configuration file—typically placed in a repository—developers ensure that every teammate and CI environment uses identical binaries, eliminating the “it works on my machine” problem. The software supports lazy installation, downloading a tool only when it is first invoked, which keeps initial setup times minimal and disk usage low. A centralized, community-driven registry supplies version metadata for hundreds of popular CLIs, from kubectl and terraform to niche utilities, while Renovate automation can propose pull requests that bump versions as soon as new releases appear, enabling continuous updates with minimal friction. Because aqua intercepts calls through a lightweight shim, the correct binary version is activated transparently, allowing seamless switching between projects that pin different tool versions. With 102 published releases to date, the project iterates rapidly; the current stable version 2.57.0 refines registry resolution performance and improves shell completion scripts. aqua fits squarely into the Development / Version Managers category and is especially useful for DevOps engineers, open-source maintainers, and organizations practicing infrastructure-as-code who need reproducible environments across laptops, containers, and cloud build agents. The software is available for free on wget.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
