I built a cloud code editor in 8th grade because I wanted to code at school

Hey Dev.to! I'm in 8th grade and I recently finished building Nestd. It's a browser-based code editor that saves your work to the cloud.

Why I built it

I code every day after school but at school I had nothing. No setup, No shared folder, nothing. So I decided to build my own solution that works from any browser on any device.

What it does

VS Code-like editor powered by Monaco (the same engine that powers VS Code)
HTML, CSS and JS tabs with live auto-preview
IntelliSense and auto-complete built in
Auto-saves to the cloud every 2 seconds
Download your project as an HTML file
Works on your phone too

I build it with

Vanilla HTML, CSS and JS
Monaco Editor
Supabase for auth and database

Live site: https://nest-d.vercel.app/

This is my biggest project so far and I'm really proud of it. Would love feedback from more experienced developers :)
