Keep your software architecture under control.
Sonargraph, ArcTree and Zügel make architecture rules enforceable, technical debt visible and AI coding agents accountable. Cleaner code, lower cost, faster teams.
14-day evaluations, no obligation. Sonargraph-Explorer is free, even for commercial use.
Software city rendered by Sonargraph: building footprint is file size, color is change frequency, height is complexity.
Three tools, one goal: code that stays maintainable
From the CI build to the IDE to your AI coding agent, every place where structure is decided.
Sonargraph
Static analysis platform for Java, Kotlin, C#, C/C++, Python, Go and TypeScript. Describe your architecture in a DSL, enforce it in every build, and explore hundreds of metrics and dependency visualizations.
Explore SonargraphArcTree
IntelliJ IDEA plugin that shows the dependency structure of Java and Kotlin code while you work. Cyclic dependencies light up in red, so unwanted coupling is caught the moment it appears.
Explore ArcTreeZügel MCP Server
Teaches your architecture to AI coding agents. Every proposed dependency is checked against your rules and for new cycles before code is written. It also disentangles legacy code bases using proven graph algorithms.

Clean architecture is the cheapest way to build software
Most systems drift into a big ball of mud one unchecked dependency at a time. Enforcing a few architecture and quality rules automatically stops that drift, and the payoff is large.
Our value propositionLower lifetime cost
Avoiding the big ball of mud easily reduces the cost of a software project by 30% or more. Developers read less and write more.
AI amplifies what it finds
A Stanford study of 120,000 developers found the best predictor of AI productivity gains was the cleanliness of the code base.
Easier to test and secure
Well-structured systems are easier to test, harder to attack and live longer, so they return more value to your organization.
Happier developers
Developers enjoy building well-structured software. Tool support makes that possible for large teams on complex systems.
