Developer Builds Full Tools Site Using Only Local LLM

A developer created SafeDevTools, a collection of browser-based utilities, using only a local AI model (Gemma 4:12B) on a MacBook M4 Pro. The project relied on Ollama, VS Code, and a custom Copilot Skill to ensure consistency across tools like JSON formatters and JWT parsers. The approach demonstrates that local LLMs can produce production-ready code without cloud APIs.
