LyteCode
Free, private, peer-to-peer

Run live coding and system-design interviews in your browser

A shared code editor and a system-design whiteboard, with video, screen share, and one-click session recording — end-to-end encrypted and peer-to-peer. Bring 2,800+ built-in problems, run code live, and just send a link. No signup, no backend.

No account needed. Your session never touches a server.

One shared editor

You and your candidate type and run code in the same editor, in real time, peer-to-peer — both cursors live.

System-design whiteboard

Flip the room to a shared whiteboard and diagram the architecture together — drag components, connect them, and talk through the design.

Record & replay

Record the whole session — keystrokes, the whiteboard, and every test run — then scrub through it later. Export a rich transcript + recording in one click.

Video and screen share

See and hear each other and share a screen, built in. No second app, no meeting link to wrangle.

End-to-end encrypted

The invite link carries the key. Keystrokes and call stay between the two of you — nothing is stored on a server.

2,800+ problems built in

Pull from the full Lyte Code catalog, ready to drop into the session and run.

Code that runs

Python and JavaScript execute right in the room — in the browser, with no setup and no backend.

Reconnect-safe

Refresh the tab or hit a flaky network and rejoin — the session picks up where you left off.

How it works

1

Start a room

Hit start and you get a private, end-to-end-encrypted room with a shareable link.

2

Share the link

Send it to your candidate. They join instantly in the browser — no account, no install.

3

Interview together

Pick a coding problem or a system-design question, work it through together on video, then download the recording + transcript when you're done.

Ready when you are

Spin up a room, send the link, and start the interview — it's free and runs entirely in the browser.
