Is JSFiddle Down Right Now?
Probably not. JSFiddle is loading editors for most developers right now. If you searched JSFiddle down or is JSFiddle down, a save or login problem is more likely. This JSFiddle status page collects live user reports.
JSFiddle is a browser-based playground for front-end code. You write HTML, CSS, and JavaScript in panes and run the result instantly. Each saved demo, called a fiddle, gets a shareable link.
Teachers, support teams, and forum helpers rely on those links daily. When a fiddle will not save or run, help threads stall. The reports above show if others hit the same problem today.
Is JSFiddle Down for Me or Everyone?
Open JSFiddle in a private window and run a tiny test fiddle. If it works there, your browser extensions or login session are at fault. If it fails there too, ask is JSFiddle down for me or everyone.
A true JSFiddle outage breaks the editor for everyone at once. A single broken fiddle usually has a code or resource error inside it, not a wider JSFiddle outage behind it.
Why Will JSFiddle Not Save My Fiddle?
Saving needs a live session, and long-idle tabs lose theirs quietly. The save button then fails without a clear message. Copy your code out, refresh the page, sign in, and save again.
Anonymous fiddles save under a temporary state that a browser cleanup can wipe. Create an account so fiddles attach to your profile. Public and private save options also differ by plan and settings.
Why Is My Code Not Running in JSFiddle?
The run depends on the framework and load type you picked. Code that waits for a page event fails when the load type skips that event. Match the setting to how the code expects to start.
Errors in one pane stop the whole result. Open the browser console to see the real message. Missing libraries are another common cause, so check the resources list before blaming the editor.
Why Does My Embedded Fiddle Show a Blank Frame?
Embeds load inside an iframe, and some sites block third-party frames by policy. If the embed is blank on your site but works on JSFiddle, your page headers are the blocker. Check your content security policy.
An ad blocker can also kill the embed silently. Test with extensions paused. Old embed codes from years ago sometimes point at retired paths, so grab a fresh embed snippet.
Why Did I Lose My Fiddles After Logging In?
Fiddles made while logged out stay tied to that anonymous state. Signing in switches you to your account library, which can look empty. The old fiddles still exist at their links if you saved the URLs.
Signing in with a different method, like GitHub after email, creates a second account. Try each login method you used before. Support can sometimes merge accounts when you prove both are yours.
Common JSFiddle Problems and Fixes
Fiddle not saving
Copy the code out, refresh, sign in, and save again. Long-idle tabs lose the session without warning.
Code not running
Open the browser console for the real error. Then check the framework and load type settings match your code.
Embedded fiddle blank
Pause ad blockers and check your site frame policy. Replace old embed code with a fresh snippet.
Lost my saved fiddles
Sign in with the same method you used when saving. Anonymous fiddles only survive at their direct links.
External resources blocked
Use https links for every library and file. Browsers block plain http resources on secure pages.

Frequently Asked Questions
How do I recover a deleted fiddle on JSFiddle?
Deleted fiddles cannot be restored from the trash, since JSFiddle keeps no recycle bin. If the link was shared, an older version may still load by adding the version number. Save backups of important fiddles.
Why does JSFiddle say my session expired?
Sessions expire after long idle time or when cookies are blocked. Sign in again and save promptly. Third-party cookie blocking in the browser causes repeat expiries.
Can I use JSFiddle without an account?
Yes, you can write and run code without signing in. Saving and organizing fiddles works better with an account. Anonymous work can vanish when browser data clears.
Why are my external libraries not loading in JSFiddle?
The library URL may be plain http, which browsers block on secure pages. Use the https version or pick the library from the resources panel. Dead CDN links also fail silently.
How do I share a specific version of a fiddle?
Each save creates a new version with its own number in the URL. Share the full URL with the version suffix to freeze that state. Later edits create newer versions.
Why does the JSFiddle editor load as a blank page?
A script blocker or strict tracking protection can stop the editor scripts. Allow the domain in your blocker and reload. Trying a private window confirms the cause fast.
