The record

Purpose: asdf is a tool version manager that uses one `.tool-versions` file to share exact tool versions with a project team.
Unified interface: asdf provides one command interface and configuration file for managing multiple tools and runtimes.
Plugins: Plugins let asdf manage tools such as Node.js, Ruby, and Elixir, and the plugin API allows support for more tools.
Version selection: asdf selects a tool version from `.tool-versions` files starting in the current directory and searching up toward the home directory.
Execution: asdf creates shims for installed executables so it can run the version specified for the current project.
Migration: asdf supports existing version files such as `.ruby-version`, `.nvmrc`, and `.node-version` on a per-plugin basis.
Shell support: The homepage lists Bash, ZSH, Fish, and Elvish support with completions available.
CI integration: The homepage says asdf provides a GitHub Action to use `.tool-versions` in CI/CD workflows.
Installation: The getting-started guide describes installation through Homebrew, Zypper, Pacman, precompiled binaries, Go, or a source build.
Supported operating systems: The installation guide lists Linux and macOS dependency instructions and provides binaries for operating-system and architecture combinations.
Limits: asdf is a tool version manager, not a system package manager, and it does not manage upstream dependencies.
Version resolution limit: If no version is listed for a tool, executing that tool produces an error unless its version is set to `system`.
Security and trust: The official pages opened for this research did not state security certifications or compliance claims.
Intended users: The documentation describes using a shared `.tool-versions` file to help project teams use the same tool versions.
Price from: Free
