How to Share Code Online & Collaborate with OutSync

Everything you need to know about sharing code in real-time, conducting live technical interviews, running code across 50+ languages, and collaborating over built-in voice.

Getting Started & Instant Sharing

Learn how to create a 1-click room, share the link with collaborators, and start coding immediately.

Real-Time Sync & Multi-Cursor Presence

How CRDT multi-cursor sync and live visual badges operate with sub-10ms latency.

Built-in WebRTC Voice Rooms

Enable crystal-clear peer-to-peer audio directly inside the coding workspace without Zoom or Discord.

Cloud Code Execution (50+ Languages)

Compile and run Python, JavaScript, TypeScript, C++, Rust, and Go code in isolated sandboxes.

10-Second Quickstart Guide

Sharing live code with OutSync takes three simple steps without creating an account or downloading dependencies:

1. Generate a Room: Click "Start Coding Free" or visit /new. A unique session ID is created immediately.
2. Share the URL: Copy the browser URL or 8-character room code and send it to your partner via Slack, Discord, or Email.
3. Code & Talk: Edit simultaneously with live multi-cursors, toggle the microphone for WebRTC voice, and click Run Code to execute test cases.

WebRTC Voice Room Setup & Audio Mesh

OutSync utilizes a direct peer-to-peer WebRTC mesh network for real-time audio. When you enable your microphone:

  • • Your browser prompts for standard microphone access permissions.
  • • OutSync exchanges SDP offers/answers over WebSocket signaling without routing audio through media servers.
  • • Audio streams are encrypted end-to-end via DTLS-SRTP for absolute conversation privacy.
