Multiplayer.app

The platform provides a shared code editor with simultaneous multi-cursor editing, integrated terminal access, voice and video communication, and persistent session state that persists beyond individual coding sessions.

This combination makes Multiplayer useful not just for scheduled pair programming sessions but for the impromptu 'can you look at this with me for five minutes?' collaboration that drives much of team learning and problem-solving in co-located engineering teams.

The technical interview use case is particularly strong: Multiplayer provides a realistic development environment where candidates can write code, run it, debug it, and navigate a real project structure rather than working in an artificial sandbox with limited tooling.

Interviewers can observe code as it's written, ask questions about design decisions, and follow the candidate's problem-solving process in real time without the awkwardness of screen sharing tools that introduce lag and limited interactivity.

Recorded session playback allows interview panels to review candidate performance after the fact and share assessments with team members who weren't in the session.

For distributed engineering teams working across time zones and remote locations, Multiplayer provides the collaborative infrastructure to maintain the high-bandwidth technical communication that traditionally required physical co-location.

Async collaboration features allow engineers to leave comments, annotations, and questions within a coding session that collaborators in different time zones can review and respond to when they're online.
