App.build, our open-source architecture reference for building agents, now supports open weights LLMs via Ollama, LMStudio, and OpenRouter.

App.build now supports running open-source language models locally through Ollama, LMStudio, and OpenRouter, eliminating API costs and rate limits while maintaining data privacy. The platform enables developers to generate full-stack applications using local inference on consumer hardware like RTX 4090s or M4 MacBooks. While current open-source models lag behind closed alternatives for autonomous app generation, they're improving rapidly and offer viable alternatives for experimentation and prototyping without vendor dependencies.
