What it does
Stop sending sensitive data to external servers. This tool converts JSON to TypeScript locally in your browser. No tracking, no ads, just instant results. Built for devs who value speed and data security.
Free, 100% private JSON to TypeScript converter. Generate interfaces, Zod schemas, and IO-TS types from nested JSON instantly. No server uploads, secure developer tool.
JSON to TypeScript is a powerful code generator that analyzes raw data to create type-safe definitions. It handles deep nesting, complex arrays, and inconsistent types, converting them into clean interfaces or Zod schemas in milliseconds. Your code is your business. We use a local-first architecture where every conversion happens in your browser memory. We never upload your JSON payloads to a server, making it safe for production data and secret internal APIs. Essential for TypeScript developers building API consumers, mobile engineers using React Native, and anyone tired of manual interface definitions. Perfect for rapid prototyping from API responses or generating validation schemas from…from json-to-ts-converter.pages.dev

But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
