In their own words
mise
mise is a development environment setup tool for Linux, macOS, and Windows. Projects can use a mise.toml file to declare tools, environment variables, and tasks, while global configuration holds personal defaults. mise installs development tools and selects versions per project, supporting hundreds of tools. It can manage project environment variables and automatically activate Python virtual environments when entering projects. Developers can share tasks and run them when files change. Shell activation is documented for bash, zsh, fish, nushell, PowerShell, and other shells. Documentation covers IDE integration and CI examples for GitHub Actions, GitLab CI, and Xcode Cloud. Safe mode can prevent project configuration from executing code or injecting environment variables in supported operations, though some backends require code execution and cannot resolve versions in that mode. The project advises reviewing other people's configuration because tasks, hooks, and some environment directives can execute code. mise is a free, open-source command-line tool under the MIT license.
Nix
Nix is a free package management and system configuration tool for creating reproducible, declarative systems. It builds packages in isolation to avoid undeclared dependencies and help keep builds consistent across machines. Users can define and share development and build environments across projects and languages, install software from URLs or source code, and use virtual machines for integration testing. Nix supports dependency resolution, lockfiles, workspaces and offline installation; its package formats include Nix expressions, derivations and flakes. The Nix Packages collection offers over 140,000 packages. The wider ecosystem supports remote builds and deployments, binary caches, cross compilation, atomic upgrades and rollbacks to earlier package versions. Nix runs on Linux and macOS, and on Windows through WSL2; multi-user Windows installation requires WSL systemd support. Documentation includes guides for GitHub Actions, Docker images, Terraform deployment, SSH provisioning and distributed builds. Nix is aimed at people familiar with command-line interfaces and plain-text editors, including developers, test engineers, DevOps engineers, system administrators, data scientists, students and open-source enthusiasts. It has no paid plan listed.
