Share Code Instantly
in Real-Time
Open a workspace, send the link, and you're pair-programming — shared cursors, terminal and all. Runs 100+ languages in a sandbox, with nothing to install.

action feed
When someone highlights a line or selects a block, everyone in the room sees it as it happens. This is what a busy workspace feels like — the cards below are a simulation of that feed.

Words we code by
Talk is cheap. Show me the code.
— Linus Torvalds
Programs must be written for people to read, and only incidentally for machines to execute.
— Harold Abelson
Code is like humor. When you have to explain it, it's bad.

Any fool can write code that a computer can understand. Good programmers write code that humans can understand.

The best error message is the one that never shows up.

Build with intent
Watch the network come online node by node as you scroll — and a thought to carry into your next commit.

Sync Latency vs Global Peer Connections
How Workspaces Spin Up
From a blank browser tab to running code with your team — here is what happens at each stage, and how long it takes.
Choose Tech Environment
Pick your stack and a fresh sandbox spawns in milliseconds, with 100+ runtimes pre-wired — JavaScript/Node, Python, Go, Rust, C++ and more, straight from the browser. There is no toolchain to install.
Initialize Secure Peer Link
One click mints your peer room. Local or permanent links are sealed with end-to-end AES-256 — your code never touches our servers in plaintext. Hand the private share URL to your team and you're live, with zero sign-up.
Live Pair-Programming Sync
Cursors, selections, and row highlights stay in lockstep across every peer at ~18ms. Drop line annotations, toggle edit-lockdowns, and jump on WebRTC voice, video, and screen-share channels without ever leaving the code.
Instant Compilation & Run
Hit run and code executes inside a hardened sandbox. Terminal output, stdout/stderr, stack traces, and debug logs stream back into the shared console in real time — everyone in the room sees the same result the moment it lands.
AI Copilot & Graphify Boost
An in-workspace copilot finishes lines, explains snippets, and writes tests on request. The Graphify optimizer routes completions through Groq for millisecond latency while trimming model tokens — faster suggestions, lower cost, your prompts never leave the encrypted session.
Save, Export & Share
Persist the workspace as a permanent room or spin it into a disposable ghost workspace. Export the whole project as a runnable zip, push straight to GitHub, or hand off a shareable read-only link — your code, packaged exactly how your team needs it.
Built for every coder
The same workspace bends to very different jobs: shipping with a team, learning without setup, teaching a room of students, or sharing code without leaving a name. Scroll to see each one.
const buffer = new SharedArrayBuffer(1024);
console.log("Workspace synchronized.");

Interactive IDE
Simulator Tour
A scripted run-through of a real session: the virtual developer opens files, writes code, runs it, and brings a second peer into the room. Scroll and the steps below light up as they happen.

Project Setup
In Seconds
This is a workspace scaffolding itself: folders, files, then the code inside them. The editor works the way VS Code does, so there is nothing new to learn before your first run.
How to create & join a workspace
Enter your username
Land on LiveCodeShare-Pro, type a display name — you're ready to spin up a room.
Fair questions
Is it actually free?+
Yes. There is no pricing page, no trial clock, and no credit card field anywhere. The only thing you bring yourself is an optional AI API key if you want the copilot wired to your own provider.
Do I need an account?+
No. Pick a display name, create or join a room, and you're in. Rooms are protected by a name + password pair you choose.
Where does my code run?+
Your choice per run: a hardened cloud sandbox covers 40+ compiled languages, JavaScript can run right in the browser, Node runs in an in-browser virtual runtime (WebNode), HTML opens as a live preview, and a local bridge can run code on your own machine.
Can I use it without internet?+
Yes — Local Offline mode keeps everything in your browser, no server involved. You can also open a folder straight from your disk and edits sync back to it through the File System Access API.
What happens to my files?+
They stay yours. Import files or whole folders by drag-and-drop (up to 25MB), and export the entire workspace as a runnable .zip whenever you want. Room content is end-to-end AES encrypted in transit.
How many people can code together?+
A room shares cursors, selections, terminal output, chat, and voice/video with everyone in it. Peer edits sync at roughly 18ms, so typing together feels local.

No signup, no credit card — there isn't even a pricing page. Open a workspace, send the link, and you'll both be typing in the same file inside a minute. If you'd rather look around first, the guided tour walks you through everything hands-on.
Works in the browser you already have. Nothing to install.
