About Archyl

Archyl is an AI-powered platform for living software architecture documentation built around the C4 model. It uses AI to analyze codebases, automatically discover components and relationships, and generate interactive C4 diagrams at every level. The tool detects drift to keep documentation aligned with the actual codebase. Archyl expresses architecture as code using a YAML DSL, enabling integration with Git workflows for versioning, reviews, and collaboration. This approach replaces manual, static diagrams with faster, more accurate, and reviewable documentation. It is designed for architects, tech leads, and development teams who need up-to-date architecture documentation without the overhead of manual updates. By automating diagram generation and maintenance, Archyl reduces the risk of outdated or inaccurate architecture records while streamlining team collaboration and decision-making processes.

Frequently asked questions about Archyl

What is the C4 model?

The C4 model is a hierarchical approach to visualizing software architecture at four levels: System Context, Containers, Components, and Code. It provides a structured way to document and understand software systems at different levels of detail.

Who should use Archyl?

Archyl is designed for architects, tech leads, and development teams who need accurate, up-to-date architecture documentation without the overhead of manual updates. It suits teams using modern software development practices.

Can I import existing architecture documentation into Archyl?

Yes, Archyl supports importing existing architecture through AI discovery from Git repositories, Architecture Decision Records (ADRs), or markdown documentation. This allows teams to migrate existing documentation seamlessly.

Does Archyl offer a free plan?

Yes, Archyl provides a free plan for individual developers. Teams can scale to paid plans as their needs grow, with transparent per-seat pricing.

Can I connect my own AI provider to Archyl?

Yes, Archyl allows users to connect their own AI providers such as OpenAI, Anthropic, Google Gemini, AWS Bedrock, or OpenAI-compatible endpoints. This bypasses the platform's AI usage limits.

How do I get started with Archyl?

To get started, create a new project in Archyl, connect your Git repository for AI discovery, and begin adding systems or importing existing documentation. The platform provides guided resources to help users create their first diagrams.
