VirtualFish is a Python virtual environment manager for the Fish shell, offering a `vf` command and a plugin system. It emulates virtualenvwrapper features like auto-activation, project management, and environment variable automation.

Use cases

  • manage python virtualenvs in fish shell
  • auto-activate virtualenv when cd into project
  • virtualenvwrapper alternative for fish
  • create and switch python environments from terminal
  • show current virtualenv in fish prompt

When to choose

  • you use the Fish shell and want virtualenvwrapper-like workflow
  • you want plugin-based virtualenv management with auto-activation

When to avoid

  • you use bash or zsh instead of fish
  • you prefer built-in venv or tools like pyenv/poetry
