Launch HN: Modelence (YC S25) – App Builder with TypeScript / MongoDB Framework

Hi all, Aram and Eduard here - co-founders of Modelence ( https://modelence.com ). After spending years on scaling our previous startup’s platform, we built an open-source full-stack TypeScript + MongoDB framework to stop solving the same auth / database / API / cron job implementations every time we created an app, and we didn’t like the idea of using multiple managed platforms for each of these to run our apps either. (Here’s our prior Show HN post for reference: https://news.ycombinator.com/item?id=44902227 ) At the same time, we were excited by the whole AI app builder boom and realized that the real challenge there is the platform rather than the tool itself. Now we’re making Modelence the first full-stack framework that’s built for coding agents and humans alike: - TypeScript is already great for AI coding because it provides guardrails and catches many errors at build time, so agents can auto-correct - MongoDB eliminates the schema managem
