StackBlitz service status
Open the provider’s incident information and match its component, region and update time to your problem. A status-page headline does not test your individual account.

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 help and reporting
Use the editor/runtime support links and a minimal non-sensitive reproduction.
Open stackblitz.com
Compare the website entrypoint with your browser or app. This website link is separate from a provider incident dashboard.
Where to report a StackBlitz problem
Use the editor/runtime support links and a minimal non-sensitive reproduction.
Open StackBlitz help / reporting. Use the contact, technical-help or account route described there. Sign-in, support entitlement and available channels can vary; a public community discussion is not a private support ticket.
Include these details in a StackBlitz 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 or 429 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: a step-by-step workflow
- Capture the original failure. Save the exact action, error and time before refreshing. Preserve drafts and check whether a submission already completed.
- Run the stackblitz.com check. Compare each response, the measurement time and available locations. A repeated click can reuse a cached observation.
- Compare the relevant provider information. Open StackBlitz status and check whether the named service and incident time fit your error.
- Test one useful difference, then report. Compare another permitted session, network or service component using the tailored checks above. Send the result and the actual app error through the reporting route on this page.
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. Compare permitted network paths
Compare Wi-Fi and mobile data only where you are permitted to do so. Keep required VPN, proxy and security controls in place, and record which network fails.
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.
Frequently asked questions about StackBlitz problems
Is StackBlitz down, or is the problem limited to one feature?
Run the stackblitz.com check and compare its original timestamps and responses with your actual error. The StackBlitz editor and browser-hosted development runtime can fail independently of the public site.
Where can I report a problem with StackBlitz?
Use the official help/reporting resource linked above. Use the editor/runtime support links and a minimal non-sensitive reproduction.
What should I check first when StackBlitz is not working?
Compare a small starter project with the affected project and note whether dependency installation or preview startup fails. Capture the runtime/browser error and failed dependency URL before clearing project state.
What information helps StackBlitz support investigate?
Project, browser/OS, runtime/install command, preview error and time with private code removed.
