Solarch

Solarch is a specialized tool for designing backend software architecture. You create a visual graph of your system using nodes (like controllers, services, repositories, and databases) and connect them with edges. As you draw, a built-in Rules Engine immediately validates every connection against established architectural patterns, preventing common anti-patterns before they happen. The core idea is architecture-first: you design the structure visually, and Solarch ensures it's correct before any code is written.

What sets Solarch apart is its hybrid approach. It uses AI (specifically LangGraph) to help generate and refine architectural plans, but it grounds these suggestions in a library of canonical patterns. The real standout feature is the strict, default-deny Rules Engine that acts as a guardrail. It won't let you draw invalid connections, like linking a controller directly to a database table. If the AI suggests something that breaks the rules, the tool automatically self-corrects and proposes a valid alternative.

This tool is built for software engineers and architects who design backend systems. It's particularly useful for teams that want to maintain clean, scalable architecture and avoid the common drift between a planned diagram and the actual implemented code. You can use it to visually plan a new microservices project, refactor an existing system's architecture, or generate a starter codebase that perfectly matches your designed structure.
