Why I stopped copy-pasting JSON into online converters and built TypeMorph
Every developer has done it. You grab a JSON response from an API, paste it into some random online tool, and get a TypeScript interface back. Fast, convenient — and potentially a huge security mistake.
I did this for years before I realized what I was actually doing: sending production API responses, internal data models, and sometimes customer data to servers I knew nothing about.
So I built TypeMorph (https://typemorph.dev) — a schema conversion tool that runs 100% in your browser. No servers. No uploads. Your data never leaves your machine.
