HOW IT WORKS

Interview in three steps

01
Create a room

Name it, pick a language, optionally attach a question. Takes ten seconds.

02
Send one link

Candidates join from the browser — no signup, no downloads, no screen-share fumbling.

03
Code together, run for real

Every keystroke syncs via CRDT. Run code in a sandbox and see output — both of you, instantly.

✓ 12 passed · 0 failed · 1.4s
Real execution, 6 languages

Python, TypeScript, Go, Rust, Java, C++ — sandboxed, with stdout and test results.

Conflict-free by construction

Y.js CRDTs under the hood. Two cursors, one document, zero “can you refresh?”

Private interviewer notes

Timestamped notes only you can see, saved with the room for debriefs.

Calm candidate experience

A simplified view with no admin chrome — and the timer is shown only if you choose.

Rooms stay reviewable

Final code, run history and notes persist after the session ends.

Built for teams

Orgs, roles and shared history — every interviewer sees the same pipeline.
