mamba-org/mamba: The Fast Cross-Platform Package Manager

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 mamba are implemented in C++ for maximum efficiency

At the same time, mamba utilize 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 (https://medium.com/@QuantStack/open-software-packaging-for-science-61cecee7fc23). The ecosystem also consists of quetz, an open source conda package server and boa, a fast conda package builder.
