fake2db vs mixer
Database datasets and Python test objects compared
fake2db generates fake data directly in supported SQL and NoSQL databases, while mixer creates populated Python model and object instances for tests. The main difference is that fake2db focuses on database-wide datasets, whereas mixer focuses on application-level test objects and relationships.
fake2db: Generate Test Databases with Fake Data
fake2db generates databases populated with realistic-looking data for development and testing. It supports several SQL and NoSQL backends, with options for row counts, locales, repeatable seeds, and custom fields.
mixer: Generate Test Data for Python Models
Mixer is a Python library for generating instances of Django, SQLAlchemy, Flask-SQLAlchemy, and other model types. It helps replace hand-written fixtures with generated test data, with controls for field values and database commits.

Key differences
- fake2db is a command-line tool for generating records in SQLite, MySQL, PostgreSQL, MongoDB, Redis, and CouchDB; mixer is a Python library for models and objects in several Python frameworks and custom classes.
- fake2db offers row counts, locales, seeds, and custom fields; mixer offers related objects, nested values, instance cycling, and customizable field generators.
- fake2db can generate data without targeting a particular application model; mixer generates instances based on model or object definitions.
- fake2db is licensed GPL-2.0; mixer metadata says NOASSERTION, while its README describes a BSD license, so check its license files.
- fake2db was last pushed on 2019-11-25; mixer lists Python 3.7+ and Django 3.0 and 3.1 support in its README.
