Try Our Collaborative Code Editor
This demo code editor allows you to write, share, and execute code directly in your browser without creating an account. It supports real-time collaboration, live code execution using WebAssembly for near-native performance, and works with multiple programming languages. You can instantly create a coding session, invite others with a simple room code, and start coding together. Experience the features of our collaborative platform with no setup required, entirely in your browser.
⚠️ This demo only allows 2 participants per room.
Are you a teacher who teaches coding?
Our collaborative code editor is integrated into PresentationAssistants.com, a platform that transforms presentations into interactive experiences. Designed for live classrooms and workshops, one person types code, and hundreds of participants instantly see it — and can run it — directly in their browser. Powered by WebAssembly, the editor runs code efficiently and safely on each participant’s device, making it far more scalable than traditional browser-based code editors. No installs, no setup, just real-time teaching power. In the production editor, the presenter remains the only one who can edit the code; participants are view-only unless the presenter grants permission to a specific audience member.
