Private Password Protected Code Rooms

Why it works

Designed for classrooms, interviews, debugging, and quick pair sessions

The product strips away account friction but keeps the controls that matter when real code is being shared.

Fast room creation

Every URL becomes a room. If it does not exist yet, the first visitor decides privacy and expiry.

Privacy you can explain

Temporary ownership, bcrypt-hashed passwords, IP throttling, and auto-expiry make the no-login model practical.

Real-time focus

Socket.io keeps editors in sync, presence is visible, and Monaco gives the interface a familiar developer feel.

FAQ preview

Questions teams ask before switching

These are the concerns we hear most when people want something simpler than a full authenticated workspace.

Do I need an account to share code?

No. Every room is anonymous by default, and the first visitor becomes the temporary owner through a secure browser token.

How do private rooms work?

Private rooms ask for a password before entry. Passwords are hashed on the backend and room access attempts are rate limited.

Can I control how long a room stays alive?

Yes. New rooms default to 24 hours, and you can choose shorter windows like 1, 6, or 12 hours or set a custom duration.
