TraceGrid: Universal Architecture Compiler

Every engineering team has lived through the same frustrating cycle: an architecture diagram is drawn on a whiteboard or documented in a wiki, and within two weeks of active feature delivery, the code moves on while the documentation stays frozen in time. When a database column gets renamed or an API response payload shifts, developers are left manually searching through repositories to guess which frontend views or backend handlers will silently break. TraceGrid was created to solve this architectural drift permanently. Instead of treating system design and code implementation as two disconnected phases, TraceGrid turns architecture into a living, bi-directional compiler. At the center of the system sits a single canonical contract: architecture.md. It captures database schemas as deterministic Mermaid entity-relationship diagrams, API endpoints as structured routing tables, and system workflows as unified request flows. TraceGrid operates fluidly in both directions. In greenfield mode, you can feed it a simple product requirement document or high-level idea string, and TraceGrid scaffolds out an initial blueprint complete with data models, endpoint contracts, and directory layouts. In brownfield mode, you can point TraceGrid at any existing real-world project directory—spanning Python, FastAPI, Express, Next.js, SQLModel, Prisma, and React—and its pure-TypeScript AST scanner statically crawls models, router definitions, and frontend API calls to compile an accurate architectural snapshot straight from source. Through its built-in engine, TraceGrid renders a real-time, three-column visual canvas mapping your entire application flow from Database Entities through API and Middleware Routes down to Frontend Components. Beyond passive visualization, TraceGrid introduces interactive blast-radius simulation. By clicking on any database entity, developers and engineering leads can instantly see a live visual cascade highlighting every downstream API route and user-facing component affected by a change. Built and structured natively using autonomous agent workflows in IBM Bob 2.0, TraceGrid eliminates guesswork, prevents broken contracts before deployment, and keeps your entire stack transparent from schema to screen.
