CondaNest: Web-based GUI Conda Manager

A fast, minimal web-based GUI for managing and cleaning Conda/Mamba environments on Linux, Windows, and macOS.

Runs a local web server that opens in your browser - no native GUI dependencies required.

Features

• List environments with path and disk usage
• Clone, rename, delete, export to environment.yml
• Bulk export or create envs from YAML folders
• Run conda clean --all from a simple dialog
• Manage global channels and strict priority
• Install packages in a environment

Installation

Install CondaNest from PyPI:

pip install condanest

Or install from source:

git clone https://github.com/aradar46/condanest.git
cd condanest
pip install .

Usage

After installation, run:

condanest

The app will automatically start a web server and open in your browser at http://127.0.0.1:8765

Platform support:

• ✅ Linux: Fully supported
• ✅ Windows: Fully supported (uses Scripts/conda.exe)
• ✅ macOS: Fully supported

The browser should open automatically on all platforms. If it doesn't, manually navigate to http://127.0.0.1:8765

Anaconda Terms of Service

If you use Anaconda or Miniconda with default Anaconda channels, you may need to accept the Terms of Service once:

conda tos accept --override-channels --channel https://repo.anaconda.com/pkgs/main
conda tos accept --override-channels --channel https://repo.anaconda.com/pkgs/r

After running these commands, retry the operation in CondaNest.

Requirements

• Python 3.10+
• Conda or Mamba installed on your system (or use the built-in Miniforge installer)
• FastAPI and Uvicorn (installed automatically via pip)

Note: CondaNest will automatically detect Conda/Mamba installations. If none are found, you can use the built-in installer to install Miniforge directly from the app.
