Gen System

Gen System is a code parsing and service generation tool that builds syntax trees and control flow graphs for local LLMs.

Gen System parses source code to generate syntax trees, symbol indexes, call graphs, and control flow graphs for Go, COBOL, CA Gen, Java, TypeScript, and Python. It reads inputs, calls, data writes, and actions as beliefs, allowing users to correct any belief to steer code generation. The generation feature plans a Go service using local models via Ollama, compiling and checking each operation before it enters the service file. It runs locally and provides an architecture studio via browser as well as an MCP server for clients like Claude Code, Cursor, and Codex. The software supports Linux and Windows with a single GPU and Ollama.
