Tach Tach is a Python tool to enforce dependencies and interfaces, written in Rust. Tach is inspired by the modular monolith architecture. Docs Discord Here's an example: Tach can enforce: 📋 Imports only come from declared dependencies 🤝 Cross-module calls use the public interface ⛓️‍💥 No cycles in the dependency graph Tach is: 🌎 Open source 🐍 Installable via pip 🔧 Able to be adopted incrementally ⚡ Implemented with no runtime impact ♾️ Interoperable with your existing systems Getting Started Installation pip install tach Setup Tach will guide you through initial project setup. Run: tach init After an introductory message, you will see a file tree interface allowing you to interactively configure your project.

If your Python code lives below your project root, or if you are working in a monorepo wi ... Read full article.
