Understanding StackBlitz connection and service problems

The StackBlitz editor and browser-hosted development runtime can fail independently of the public site.

The checker above requests stackblitz.com from eight configured locations and shows the responses and measurement times. Compare those observations with the actual StackBlitz action that failed. A homepage response alone cannot verify an account, app workflow or transaction.

StackBlitz status information and official help

StackBlitz service status

Check whether the provider lists a problem with the feature you use. Look at the update time and any affected regions.

StackBlitz help and reporting

Use the editor/runtime support links and a minimal non-sensitive reproduction.

Open stackblitz.com

Open the website in your browser and compare it with the result above.

Where to report problems with StackBlitz

Open StackBlitz help / reporting. Use the provider's customer-service or account-help route for the affected product. Sign-in may be required for private account questions.

Details to include in your report

Project, browser/OS, runtime/install command, preview error and time with private code removed.

Attach the checker’s downloaded JSON if it helps show the hostname, regional responses and original timestamps. Describe what happened in your browser or app as well. A report sent to WebsiteDown.org is not automatically forwarded to StackBlitz.

What to check when StackBlitz is not working

These are troubleshooting comparisons, not claims that StackBlitz is currently experiencing a particular incident.

Start with the action that failed

Compare a small starter project with the affected project and note whether dependency installation or preview startup fails.

Narrow down the affected service

Capture the runtime/browser error and failed dependency URL before clearing project state.

Read the actual checker response

A 403 Forbidden or 429 Too Many Requests means the host answered but refused or limited that request. A timeout gives no HTTP response. Keep those outcomes separate and check the available-region count before treating the result as broad evidence.

How to check if StackBlitz is down

Save the error. Note what you were doing and when it failed. Save unfinished work before refreshing.
Run the stackblitz.com check. Look at the regional results and when they were checked. Checking again may return a cached result.
Check for a service notice. Open StackBlitz status and check whether the named service and incident time fit your error.
Try another browser or network. Use the specific checks above to narrow down the problem. If it continues, send the error and time through the official help link.

If StackBlitz Is Not Working Only For You, Start Here

Use these local troubleshooting steps after the down-check workflow when StackBlitz seems broken only for you. This section focuses on app, browser, account, and network fixes.

1. Compare browser sessions

Open stackblitz.com in your current browser, then test in a private window or second browser. If only one session fails, compare its account, cookie and extension context before assuming the entire service is unavailable.

2. Preserve a working account session

Keep an existing working session and preserve unsaved work. For a sign-in failure, use the official account-help route. Avoid repeated password or security resets until you confirm this is not a broader StackBlitz issue.

3. Try another network

If possible, compare Wi-Fi with mobile data and note which one fails. Leave any required work VPN or security settings in place.

4. Capture support-ready evidence

Save timestamp, device, network type, exact error, final URL, and status code. Use the check workflow above before contacting StackBlitz support.
