## What it is
Mamba is a fast, cross-platform package manager written in C++ that acts as a drop-in replacement for conda, using the libsolv dependency solver and parallel downloads for much faster operations. The project ships mamba (conda-compatible CLI), micromamba (a standalone statically-linked executable suited to CI and containers), and libmamba/libmambapy (a C++ library with Python bindings).

## Use cases
- faster alternative to conda for installing packages
- resolve conda dependencies quickly
- manage Python environments from the command line
- install conda packages in a CI pipeline without Python
- set up reproducible scientific computing environments
- build minimal container images with a self-contained package manager

## When to choose
- You use conda or conda-forge packages and want dramatically faster downloads and dependency solving
- You need a standalone, dependency-free executable (micromamba) for CI/CD or Docker workflows
- You want programmatic access to conda package management via libmamba or its Python bindings
- You need a cross-platform environment manager covering Windows, macOS, and Linux including ARM64/PPC64LE

## When to avoid
- Your workflow is pip/PyPI-only with no conda packages or environments involved
- You rely on conda features or plugins not yet reimplemented in mamba
- You need a graphical package manager rather than a command-line tool
