Mamba: The Fast Cross-Platform Package Manager

mamba header image

part of mamba-org
Package Manager mamba	Package Server quetz

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 mamba are 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 the conda-forge ecosystem, which also consists of quetz, an open source conda package server.

You can read our announcement blog post.

micromamba

micromamba is the statically linked version of mamba.

It can be installed as a standalone executable without any dependencies, making it a perfect fit for CI/CD pipelines and containerized environments.

See the documentation on micromamba for details.

`mamba` v.s. `micromamba`

mamba has to be preferred when:

libmambapy or libmamba is used by other software in the same environment.
Scenarios where regular updates to libraries are required (especially for security).
Environments are focused on reducing disk space usage for dependencies.

micromamba has to be preferred when:

Relying a single self-contained executable is required.
A miniforge distribution is not present.
Usage requires minimal runtime.

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 micromamba create with the -f option, providing an environment lockfile whose name ends with -lock.yml or -lock.yaml; for instance:

bash micromamba create -n my-env -f conda-lock.yml

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 conda environments.

Differences with `conda`

While mamba and micromamba are generally a drop-in replacement for conda there are some differences:

mamba and micromamba normalize MatchSpec strings to the simplest form, whereas conda use a more verbose form This can lead to slight differences in the output of conda env export and mamba env export.

Development installation

Please refer to the instructions given by the official documentation.

API and ABI stability

The Mamba project uses semantic versioning of the form MAJOR.MINOR.PATCH. While we try to keep things stable for users, we also need to make breaking changes to improve Mamba and reduce technical debt. Future versions of Mamba may give stronger guarantees.

`libmamba` (C++)

We are not aware of consumers of the C++ API, so we give ourselves room for improvements. For libmamba, the term backward compatible is understood as follows:

ABI backward compatible means that you can replace the library binary files without recompiling your code with the updated headers. The observed behavior will be the same, except for bugs (disappearing, hopefully) and performance.
API backward compatible means that you must recompile your code with the new library version code, but you won't need to change your code, just re-build it. This applies as long as you did not use any declaration understood to be private, for instance in the detail sub-namespaces. The observed behavior will be the same, except for bugs (disappearing, hopefully) and performance. When declarations are deprecated but not removed and still functional, we consider it also backward compatible, as only the observed behavior during compilation changes.

With this in mind, libmamba offers the following guarantees:

PATCH releases are API and ABI backward compatible;
MINOR releases are API compatible for declarations in mamba/api, They can break API elsewhere and ABI anywhere;
MAJOR releases make no guarantees.

`libmambapy` (Python)

For libmambapy, the term API backward compatible implies that your Python code will work the same for a newer version of libmambapy as long as you did not use any declaration understood to be private, for instance accessed with a name starting with an _. The observed behavior will be the same, except for bugs (disappearing, hopefully) and performance. When declarations are deprecated but not removed and still functional, we consider it also backward compatible, as the behavior is only observable when activating Python DeprecationWarning, which is usually only activated in development.

With this in mind, libmambapy offers the following guarantees:

PATCH releases are API backward compatible;
MINOR releases are API backward compatible;
MAJOR releases make no guarantees.

`mamba` and `micromamba` (executables)

For executables, the term backward compatible applies to programmable inputs and outputs and means that your code (including shell scripts) will work with newer versions of the executable without modifications. Programmable inputs/outputs include executable name, command line arguments, configuration files, environment variables, JSON command line outputs, and files created. It excludes human-readable output and error messages, and thus deprecation warnings written in the human-readable output.

With this in mind, mamba and micromamba offer the following guarantees:

PATCH releases are backward compatible;
MINOR releases are backward compatible;
MAJOR releases make no guarantees.

Support us

Only mamba and micromamba 2.0 and later are supported and are actively developed.

The 1.x branch is only maintained for addressing security issues such as CVEs.
