Built for high school classrooms

Teach HTML & CSS
without the friction

Create coding assignments, share a join code, and watch your students build real websites — all in the browser. No installs, no accounts for parents.

How it works

1

Create a class

Sign up as a teacher, create a classroom, and write your assignment — with starter HTML, CSS, and instructions.

2

Share your code

Students register and join with a short class code. They're in the editor in under a minute — no email from parents required.

3

Review & grade

Students submit when ready. You see their live site, leave feedback, and record a grade — all from one page.

Everything your class needs

Monaco editor

The same editor that powers VS Code — syntax highlighting, autocomplete, and auto-formatting built in.

Live preview

Students see their page update as they type. A full-site preview with JavaScript runs on a separate subdomain.

Assignment management

Write instructions in rich text, provide starter code, set due dates, and publish when ready. Duplicate across classes in one click.

Feedback & grading

Leave inline comments, answer student questions, and record a grade. Students can move back to draft and keep improving.

Image uploads

Students can upload images directly into their project and reference them with a copy-to-clipboard snippet.

Autosave & version history

Work is saved automatically. Version snapshots are taken every 10 minutes so nothing is ever lost.
