Hey, I'm Anton, a solo developer based in George, South Africa. I built Underpeaks because I kept hitting the same wall on every project: building the same backend plumbing over and over, and if a client needed both a web app and a mobile app, keeping one data model in sync across two codebases by hand. Underpeaks generates real Flutter and Next.js code from a single data model. Not scaffolding you throw away, not a black box you're locked into. Actual code you own and can edit. It runs on five databases (Supabase, Postgres, MySQL, MongoDB, Firebase) through one adapter, so you're not stuck with whatever you picked on day one. Self-host it free with Core, or let us host it with Studio. What it's not: a website builder. If you already know how to build a frontend, we're not handing you a drag-and-drop editor to fight with. We do the backend. Your frontend stays yours. Honest limits: the dedicated Flutter/Next.js SDK is still on the roadmap, not live yet. This is v1, built by one person, and I'm here all day to answer anything. What's the most annoying backend problem you keep rebuilding on every project?
