Hey Product Hunt 👋 I'm TD the solo maker behind FrameworkKit. This started from a small but constant annoyance: every time I needed to convert a schema — Zod to JSON Schema, a JSON sample to Zod, an OpenAPI spec to validators — I'd paste it into some random online converter and immediately wonder "where is this data actually going?" For work schemas, that never felt right. So I built FrameworkKit to run entirely in your browser. Nothing you paste leaves your machine — no uploads, no backend, no signup. What's in it today: • Zod ↔ JSON Schema (Draft 2020-12, Draft 7, OpenAPI, AJV) • JSON → Zod and TypeScript → Zod • OpenAPI → Zod validators • Next.js metadata + tsconfig helpers I also wrote a bunch of guides for the stuff people actually get stuck on — like Zod 4's new native z.toJSONSchema() and flatten() vs treeify() for errors. It's free and I'm building it in the open. I'd genuinely love feedback — especially: what schema conversion or TypeScript chore do you do most often that still feels painful? That's what I want to build next. Thanks for checking it out 🙏
