Polylith

Polylith is a software architecture that applies functional thinking at the system scale. It helps us build simple, maintainable, testable, and scalable backend systems.

Where to begin?

  • If you'd prefer to start with a high-level technical overview of the architecture, then skip straight to Polylith in a Nutshell.

  • If you learn faster with audio/visual presentations, then you can start by watching the videos.

  • If you want to jump straight into some code, then head over to the Polylith RealWorld example app.

  • If you're feeling concerned about how a new architecture might affect your deployment setup, then read Transitioning to Polylith.

  • If you prefer to start from the beginning, and take things at your own pace, then you're already in exactly the right place - just keep reading.

A brief introduction

Polylith is an architecture that allow us to compose systems out of LEGO-like bricks:

If you join us on this journey, then you'll discover how Polylith structures code to help you develop faster and communicate your ideas better. By the end, you'll understand how to combine building blocks into services and tools:

We hope you'll agree that Polylith makes building systems almost as fun as playing with LEGO®!

Let's start with why Polylith may be a good idea.
