## What it is
aqua is a declarative CLI version manager written in Go that manages tool versions per project via configuration files, with lazy installation and a registry ecosystem. It unifies tool installation across teams and CI, supports continuous updates via Renovate, and provides security features like checksum verification and SLSA provenance.

## Use cases
- manage cli tool versions per project declaratively
- unify tool versions across a team and ci pipelines
- install dev tools lazily only when executed
- update cli tools automatically with renovate
- switch between multiple versions of the same tool seamlessly
- securely install binaries with checksum and provenance verification
- replace asdf or homebrew for managing dev tools

## When to choose
- you need consistent tool versions across local machines and CI
- you want lazy installation so tools install on first use
- you want declarative config files checked into version control
- you need cross-platform support for Windows, macOS, and Linux
- you want automated tool updates via Renovate

## When to avoid
- you only need to manage one or two language runtimes with mature native managers
- you prefer imperative installation scripts or package managers like apt or brew
- your tools are not available in aqua's registries and you don't want to write registry configs
