Domain Driven Design Python Packages

eventsourcing

A library for event sourcing in Python.

pymessagebus

A MessageBus / CommandBus light implementation for Python. Simple pattern that allows a clean decoupling in projects of any size! :-)

flama

The production framework for Predictive and Generative AI. Serve any model as an API in one line, with OpenAI/Anthropic/Ollama-compatible endpoints, a built-in chat UI, and native MCP.

hexcore

Reusable core for Python projects with hexagonal architecture, DDD, CQRS and background tasks. Ships the abstractions and the infrastructure: SQL session layer, FastAPI factories, worker runner, dynamic cron and identity.

tiferet

Build an app, the beautiful way.

forze

Python toolkit for hexagonal backend services — domain and application layers that import nothing from your framework, database, or transport

value-object-pattern

The Value Object Pattern is a Python 🐍 package that streamlines the creation and management of value objects 📦 in your projects. Value objects are immutable, self-validating objects that represent descriptive aspects of the domain with no conceptual identity.

minos-microservice-common

🐍 Minos is a framework which helps you create reactive microservices in Python

protean

Pragmatic Framework for Ambitious Applications

msb-arch

A dependency-free domain layer for Python: entities, invariants and operations independent of UI, storage and transport — driven through one entry point by requests that are data, recordable and replayable.

django-ddd

Django the DDD way

teaql

AI-native Python library and runtime for business apps: model-driven, typed SQL queries, safe expressions and audited graph mutations.

fractal-toolkit

Fractal is a scaffolding toolkit for building SOLID logic for your Python applications.

minos-microservice-networks

🐍 Minos is a framework which helps you create reactive microservices in Python

dddesign

Domain Driven Design Library

guara

Guará is a Python framework for business logic expression. It allows you to write production code and tests as executable domain language

starlette-api

The production framework for Predictive and Generative AI. Serve any model as an API in one line, with OpenAI/Anthropic/Ollama-compatible endpoints, a built-in chat UI, and native MCP.

clock-pattern

The Clock Pattern is a Python 🐍 package that turns time into an injectable dependency 🧩. By replacing ad-hoc datetime.now() calls with a swappable Clock interface 🕰️ you unlock deterministic tests 🧪 and decouple business logic from the OS clock.

minos-microservice-saga

🐍 Minos is a framework which helps you create reactive microservices in Python

aikicore

Build an app, the beautiful way.

okto-pulse-core

Transport-neutral domain engine for Okto Pulse: governed SDLC workflows, knowledge graph contracts, and 281 MCP tools.

pytest-orm-boundaries

Enforce the DDD aggregate boundaries you define in your ORM

minos-microservice-aggregate

🐍 Minos is a framework which helps you create reactive microservices in Python

pycider

Aggregate Composition for Python. A domain driven design architecture.
