Be honest: how many interviews have started with "can you hear me? let me share my screen... wait, can you see it now?"
Pairing on a problem should feel like pairing. So on jsitor.com you can now run a live coding interview with one link.
What an interview looks like
That's the demo from the jsitor.com home page. Maya is interviewing Dev on a classic two-sum problem. Both of them are in the same file, each with a named, coloured cursor. Dev writes the solution, Maya follows along and drops a follow-up right in the editor: "Nice! Can you do it in O(n)?"
No screen-share lag, no "which window are you looking at?", and nobody needs to install anything.
Why it's easy
1. One link to start. Open a project or pen, save a project or pen to start with and , hit Collab, copy the link and send it. That's the whole setup.
2. Your candidate doesn't need an account. A guest opens the link, picks a display name and they're in. There's no signup wall in the middle of someone's interview.
3. You see everything they do. Remote cursors with names, avatars and colours, plus a shared muse pointer anywhere in the app window. You can point at a line and say "what happens here?" and they can see it.
4. The code actually runs. jsitor runs a real Node.js runtime inside the browser tab. The candidate can npm install, run the file and see the output without a remote sandbox to wait for. Pens run plain HTML, CSS and JS with instant preview for front-end rounds.
5. You choose how much to sync.
| Mode | What's shared |
|---|---|
| Detached (default) | Only the code. Everyone keeps their own panels and terminal. |
| Sync | Files, tabs, run/stop, terminal and panel state mirror to everyone. Handy when you want to walk someone through. |
6. Sessions are time-boxed. A session lasts an hour by default, with a countdown in the top bar. When it ends, the links stop working, and you can end it yourself at any time.
Run your first interview in 60 seconds
- Go to jsitor.com and open a pen or project
- Paste in your problem, such as a function stub and a few test cases
- Hit Start to begin a collab session
- Send the link to your candidate
- Code together 🎉
Not interviewing? It works just as well for pair programming, debugging with a teammate or teaching a friend.
It's free to try, so kick the tires
Make up a problem and pair with a colleague. Run a mock interview with a friend. Try it on a bug that's been bugging you.
Then tell me in the comments:
- What would make this better for your interview process?
- What do you wish you could see while a candidate codes?
- What broke? I'll fix it.
👉 Start a session at jsitor.com
Happy interviewing! 🧡
