Many tools have been written for working with PyMongo. If you know of or have created a tool for working with MongoDB from Python please list it here.


We try to keep this list current. As such, projects that have not been updated recently or appear to be unmaintained will occasionally be removed from the list or moved to the back (to keep the list from becoming too intimidating).

If a project gets removed that is still being developed or is in active use please let us know or add it back.

ORM-like Layers#

Some people have found that they prefer to work with a layer that has more features than PyMongo provides. Often, things like models and validation are desired. To that end, several different ORM-like layers have been written by various authors.

It is our recommendation that new users begin by working directly with PyMongo, as described in the rest of this documentation. Many people have found that the features of PyMongo are enough for their needs. Even if you eventually come to the decision to use one of these layers, the time spent working directly with the driver will have increased your understanding of how MongoDB actually works.


MongoEngine is another ORM-like layer on top of PyMongo. It allows you to define schemas for documents and query collections using syntax inspired by the Django ORM. The code is available on GitHub; for more information, see the tutorial.


MincePy is an object-document mapper (ODM) designed to make any Python object storable and queryable in a MongoDB database. It is designed with machine learning and big-data computational and experimental science applications in mind but is entirely general and can be useful to anyone looking to organise, share, or process large amounts data with as little change to their current workflow as possible.


Ming is a library that allows you to enforce schemas on a MongoDB database in your Python application. It was developed by SourceForge in the course of their migration to MongoDB. See the introductory blog post for more details.


MotorEngine is a port of MongoEngine to Motor, for asynchronous access with Tornado. It implements the same modeling APIs to be data-portable, meaning that a model defined in MongoEngine can be read in MotorEngine. The source is available on GitHub.


uMongo is a Python MongoDB ODM. Its inception comes from two needs: the lack of async ODM and the difficulty to do document (un)serialization with existing ODMs. Works with multiple drivers: PyMongo, TxMongo, motor_asyncio, and mongomock. The source is available on GitHub

No longer maintained#


PyMODM is an ORM-like framework on top of PyMongo. PyMODM is maintained by engineers at MongoDB, Inc. and is quick to adopt new MongoDB features. PyMODM is a “core” ODM, meaning that it provides simple, extensible functionality that can be leveraged by other libraries to target platforms like Django. At the same time, PyMODM is powerful enough to be used for developing applications on its own. Complete documentation is available on readthedocs.


The MongoKit framework is an ORM-like layer on top of PyMongo. There is also a MongoKit google group.


minimongo is a lightweight, pythonic interface to MongoDB. It retains pymongo’s query and update API, and provides a number of additional features, including a simple document-oriented interface, connection pooling, index management, and collection & database naming helpers. The source is on GitHub.


Manga aims to be a simpler ORM-like layer on top of PyMongo. The syntax for defining schema is inspired by the Django ORM, but Pymongo’s query language is maintained. The source is on GitHub.


Humongolus is a lightweight ORM framework for Python and MongoDB. The name comes from the combination of MongoDB and Homunculus (the concept of a miniature though fully formed human body). Humongolus allows you to create models/schemas with robust validation. It attempts to be as pythonic as possible and exposes the pymongo cursor objects whenever possible. The code is available for download at GitHub. Tutorials and usage examples are also available at GitHub.

Framework Tools#

This section lists tools and adapters that have been designed to work with various Python frameworks and libraries.

Alternative Drivers#

These are alternatives to PyMongo.

  • Motor is a full-featured, non-blocking MongoDB driver for Python Tornado applications.

  • TxMongo is an asynchronous Twisted Python driver for MongoDB.

  • MongoMock is a small library to help testing Python code that interacts with MongoDB via Pymongo.
