The Fast Cross-Platform Package Manager

mamba
mamba is a reimplementation of the conda package manager in C++.
- parallel downloading of repository data and package files using multi-threading
- libsolv for much faster dependency solving, a state of the art library used in the RPM package manager of Red Hat, Fedora and OpenSUSE
- core parts of
mambaare implemented in C++ for maximum efficiency
At the same time, mamba utilizes the same command line parser, package installation and deinstallation code and transaction verification routines as conda to stay as compatible as possible.
Mamba is part of a bigger ecosystem to make scientific packaging more sustainable. You can read our announcement blog post.
The ecosystem also consists of quetz, an open source conda package server and boa, a fast conda package builder.
Installation
Please refer to the mamba and micromamba installation guide in the documentation.
Additional features in Mamba and Micromamba
mamba and micromamba come with features on top of stock conda.
repoquery
To efficiently query repositories and query package dependencies you can use mamba repoquery or micromamba repoquery.
See the repoquery documentation for details.
Installing lock files
micromamba can be used to install lock files generated by conda-lock without having to install conda-lock. Simply invoke e.g. micromamba create -n my-env -f conda-lock.yml with an environment lockfile named *-lock.yml or *-lock.yaml.
setup-micromamba (setup-miniconda replacement)
setup-micromamba is a replacement for setup-miniconda that uses micromamba.
It can significantly reduce your CI setup time by:
- Using
micromamba, which takes around 1 s to install. - Caching package downloads.
- Caching entire
condaenvironments.
micromamba
micromamba is a small, pure-C++ reimplementation of mamba/conda. It strives to be a full replacement for mamba and conda. As such, it doesn't use any conda code (in fact it doesn't require Python at all).
See the documentation on micromamba for details.
Development installation
Please refer to the instructions given by the official documentation.
