About

I am the founder and developer of HtmlRunner — a free, private platform for running HTML, CSS and JavaScript instantly in your browser. I started HtmlRunner in late 2024 with a simple idea: powerful tools should be free and accessible to every human being, no matter where they were born.

Every lesson and tool on HtmlRunner is built and live-tested by me. No AI-spun paragraphs, no outsourced content, no data collection. Your code runs in a sandboxed iframe inside your browser and never leaves your device.

25% of HtmlRunner’s revenue goes directly to teaching institutes that educate students worldwide — from Bangladesh to Brazil, Nigeria to Nepal. By using HtmlRunner, you help fund that mission.

What I build

Free online tools for developers, students and newcomers: HTML Runner, Code Runner, HTML Compiler, CSS Minifier, HTML Cleanup, SSL Checker, Subdomains Finder and the Learn platform with 92 interactive lessons across HTML, CSS, JavaScript, Node.js and PHP — each with a live editor.

Elsewhere

Find me on Facebook, LinkedIn and GitHub. Or reach me directly at contact@htmlrunner.com.

Writing & teaching

I write every Learn lesson in plain language, test every example live, and keep the explanations short. The goal is not to impress with jargon but to help you build your first page, style it, and make it interactive — today.

If you want to start, try What is HTML? or open the Playground and start typing.
