lazyvenv

A TUI for managing Python virtual environments.

lazyvenv shows the virtual environments in the current directory, lets you inspect their installed packages (including origin, size, and metadata), and create, delete, activate, and deactivate environments — all from one keyboard- driven interface.

Requirements

• Python 3.13 or newer
• uv — used to list interpreters and create venvs
• zsh, bash, or sh (for the activation shell hook)

Install

uv tool install lazyvenv

This installs the lazyvenv command globally, outside any project venv — which is required for activation to work reliably.

Shell integration (for activation)

Pressing a inside the app marks a venv to be (de)activated, and the change is applied when you quit. For that to work, add the wrapper function to your shell config:

# ~/.zshrc or ~/.bashrc
eval "$(lazyvenv init zsh)"   # or: lazyvenv init bash

Restart your shell (or source the file). Without this hook the app still works, but a will show a warning instead of activating.

Usage

Run lazyvenv inside any directory containing virtual environments (it scans the directory itself and its immediate children for pyvenv.cfg files):

cd your-project
lazyvenv
