Launch HN: Modelence (YC S25) – App Builder with TypeScript / MongoDB Framework
Summary
Modelence is an open-source full-stack framework built on TypeScript and MongoDB to reduce boilerplate for AI-powered apps. It emphasizes coding agents and humans alike, offering built-in auth, database, cron, and observability, plus a Claude Agent SDK-based app builder and cloud/dev environment. The post frames the framework as a foundational platform for AI development rather than merely a simple app builder.
