Questions people ask
Is my code saved?
Yes, in your own browser, every time you type. It is not uploaded to our server. Use Download to keep a file on your device.
How does the share link work?
Your code is packed into the link itself. Anyone with the link sees the same code. Very long code is better shared as a downloaded file.
Can I use libraries like Bootstrap?
Yes. Add the library link in your HTML with a normal script or link tag, the same as on a real website.
Is it safe to run code here?
The preview runs in a locked box that cannot reach this website, your cookies or other tabs. Code from a share link does not run until you press Run.
