Archyl - AI-Powered Architecture Documentation | C4 Model Diagrams

Create interactive C4 architecture diagrams, discover architecture from code with AI, and keep docs in sync with Architecture as Code (YAML DSL).

Making architecture visible

We believe every organization deserves clear visibility into their software architecture. That's why we built Archyl.

Archyl was founded in 2025 after more than 20 years of experience in software consulting. Throughout those years, we witnessed the same challenge repeatedly: organizations struggling to understand, document, and communicate their software architecture.

Complex systems became black boxes. Knowledge lived only in the minds of a few senior engineers. Onboarding new members took months instead of days. Architecture decisions were made without a clear picture of the existing system.

We created Archyl to solve these problems. By combining the proven C4 model with AI-powered discovery, we make it simple for any organization to gain complete visibility into their architecture and keep their documentation always up to date.

We want to provide architecture observability to everyone, the simpler way.

We believe complex systems can be understood when visualized properly. Clarity drives better decisions.

Powerful tools don't have to be complicated. We focus on making architecture documentation effortless.

We leverage AI to automate the tedious parts, so organizations can focus on building great software.

What is the C4 model?

The C4 model is a hierarchical approach to visualizing software architecture at four levels of abstraction: • Level 1 - System Context: Shows your system and how it interacts with users and other systems • Level 2 - Containers: Shows the high-level technical building blocks (applications, databases, etc.) • Level 3 - Components: Shows the internal structure of a container • Level 4 - Code: Shows how a component is implemented
