Summary

mise is a free, open-source development environment setup tool for Linux, macOS, and Windows. A project's `mise.toml` can declare development tools, environment variables, and tasks; global configuration can hold personal defaults. mise installs tools and selects versions per project, with support for hundreds of tools. It can manage project environment variables and automatically activate Python virtual environments when entering projects. Teams can share project tasks and run them when files change. Shell activation is documented for bash, zsh, fish, nushell, PowerShell, and others, and the documentation covers IDE integration plus CI examples for GitHub Actions, GitLab CI, and Xcode Cloud. Safe mode can block project configuration from executing code or injecting environment variables in supported operations. However, some backends require code execution and cannot resolve versions in safe mode. The project also advises reviewing configuration from others because tasks, hooks, and some environment directives can execute code. mise is MIT licensed.

Who it is for

mise suits developers who want project-specific tool versions, environment settings, and shared tasks in configuration. Its safe-mode limitations and the possibility of executable project configuration are worth considering when using files from others.

What is good

  • Supports hundreds of development tools.
  • Configures tools, variables, and tasks per project.
  • Can activate Python virtual environments on entry.
  • Documented shell activation includes PowerShell and fish.
  • Includes GitHub Actions, GitLab CI, and Xcode Cloud examples.

What to know first

  • Some backends cannot resolve versions in safe mode.
  • Tasks, hooks, and directives may execute code.
  • Configuration from others should be reviewed.

Verdict

mise combines tool-version management with project environments and task running across several shells and CI systems. Its configuration can execute code, so review project files and be aware of what safe mode does not support.
