I built a free, no‑signup DevToolkit – README generator, .gitignore generator, and license selector (all in your browser)

Hey everyone!

I’m a 14‑year‑old developer from Hong Kong. Over the summer I built a simple toolkit for developers because I was tired of Googling the same basic stuff every time.

It’s a single-page (well, now multi‑page) site that lets you:

• Generate a professional README.md with live preview (using marked.js)
• Create a .gitignore for 21+ languages/frameworks with OS options
• Browse and copy 8 common open‑source licenses with plain‑English summaries

Everything runs in your browser – no data leaves your computer, no ads, no tracking. I built it with plain HTML/CSS/JS and hosted it on GitHub Pages.

I’d love any feedback – design suggestions, feature ideas, bug reports. Thanks for checking it out!
