I started coding in 2006. By 2016, I had a vision: build a platform where anyone can write code and see results instantly. No setup. No configuration. Just code.

That vision became PlayCode.

The technical challenge was ambitious: run Node.js modules directly in the browser, without Node.js. Everyone said it couldn't be done efficiently. After years of R&D and extensive customization of Rollup, I built a bundler that runs entirely in-browser, and it's actually faster than the server-side original.

Today, PlayCode serves over 1.1 million developers worldwide. From beginners learning their first loops to professionals prototyping production code, the platform handles 23 million projects and counting.

My tech stack spans JavaScript, TypeScript, Python, and Go, with deep expertise in browser technologies, bundlers, and real-time systems. Every feature in PlayCode is built with one goal: remove friction between thinking and coding.

PlayCode continues to evolve based on community feedback. The latest addition, an AI coding agent that works like Cursor, right in your browser, represents the next chapter: intelligent assistance that understands your project and writes code alongside you.

Thanks for being part of this journey. Let's keep building.
