| Installation | The docs recommend installing Mamba through the Miniforge distribution, which comes with conda-forge preconfigured, and also document Miniforge Docker images. | Nimble is bundled with Nim, and the guide provides manual installation instructions for POSIX systems and Windows. |
| Lock files | Micromamba can install conda-lock environment lock files directly. | The nimble.lock file pins exact dependency versions so developers can use the same versions across a project. |
| Lockfile support | Yes | Yes |
| Purpose | Mamba is a fast, robust, cross-platform package manager that manages conda environments. | Nimble is the default package manager for the Nim programming language. |

In their own words
Mamba
Mamba manages conda environments across Linux, macOS, Windows, API, and self-hosted setups. It creates and activates environments, installs packages, and runs commands inside them. It works with conda packages and supports most conda commands; its parallel downloads and libsolv solver speed package resolution. The framework includes the mamba command-line interface, the libmamba C++ library, micromamba, and Python bindings. Environment creation accepts text, Conda YAML, explicit, and conda-lock YAML specifications, and micromamba can install conda-lock files directly. The repoquery command searches repositories and can display direct, recursive, and reverse dependencies. Environments are self-contained prefixes that can manage native dependencies across programming languages. Mamba documents verification for package archives and extracted files, while repository index verification remains experimental. By default, it warns and asks for confirmation before transactions run package link scripts that can perform system operations. Mamba is free, open-source software under the BSD-3-Clause license, with lockfile support.
