Fast first-pass QA before deeper monitoring or manual review.
Quick answer
IsItCrashing is a free website crash checker that lets users enter a URL and scan for broken pages, failed requests, blank pages, broken critical assets, and website health issues.
How the scan works
First, enter a public website URL. IsItCrashing normalizes the URL, supports HTTP and HTTPS, removes unsafe parts, and blocks private network targets for security.
Then the scanner discovers internal pages from the website sitemap and public links, checks each discovered page, groups failures, and returns a focused report of working and failed pages.
When to run a scan
Use IsItCrashing when you need a fast answer about whether public pages are failing after a deploy, migration, content update, redirect change, plugin update, or campaign launch.
The scanner is designed for practical first-pass triage. It does not replace logs, observability, manual QA, accessibility testing, or long-term monitoring.
What it can detect
- Broken pages such as 404 Not Found URLs.
- Server errors such as 500-level responses.
- Timeouts, redirect loops, and network failures.
- Blank pages where visible content does not load.
- Broken critical assets such as scripts, stylesheets, preload files, and important media.
- Important frontend JavaScript crashes when browser scanning is configured.
How it compares
Compared with a basic uptime checker, IsItCrashing checks more than one URL and reports specific failed pages. Compared with a broken link checker, it checks whether discovered pages actually load and whether critical resources fail. Compared with manual QA, it is broader and faster, but less contextual.
How to use the report
Start with failed pages, group them by error type, and fix high-value paths first. For product teams, that usually means signup, checkout, pricing, documentation, and support pages. For SEO teams, prioritize indexed URLs and pages linked from navigation or sitemaps.
Use it before deeper QA
IsItCrashing is best used as a fast first-pass website crash and broken page scanner before deeper QA, monitoring, logs, and manual product review.
FAQ
What is IsItCrashing?
IsItCrashing is a free website crash checker that lets you enter a public URL and scan discovered pages for broken pages, failed requests, blank pages, broken critical assets, and website health issues.
Is IsItCrashing free to use?
Yes. IsItCrashing is free to use for first-pass website health checks. You do not need to install an agent or add code to your site.
Is this the same as an uptime checker?
No. A basic uptime checker usually tests one URL. IsItCrashing discovers internal pages and reports specific failed pages, blank responses, broken critical assets, and browser crashes when browser checks are available.
What does the scanner check?
The scanner checks discovered public pages for HTTP 404 and 500 errors, timeouts, redirect loops, blank content, broken critical scripts or styles, failed important requests, and JavaScript crash signals when browser scanning is configured.
Can it scan every page on a website?
It discovers pages from the sitemap and public internal links up to configured scan limits. Very large sites, private pages, unlinked pages, and authenticated areas may require a dedicated crawler or manual QA.
Does it detect JavaScript errors?
It can detect important JavaScript crashes on browser-checked pages when browser scanning is configured. It is not a replacement for runtime error monitoring, logs, or a full frontend observability setup.
Can it find every website bug?
No automated scanner can find every bug. Use IsItCrashing as a fast first-pass website crash and broken page scanner before deeper QA, monitoring, accessibility testing, or manual review.
Who should use IsItCrashing?
It is useful for developers, QA testers, SEO teams, agencies, marketers, website owners, and product teams that need a quick check after deployments, migrations, CMS edits, or campaign launches.
Can I scan private staging websites?
Only if the staging website is publicly reachable over HTTP or HTTPS. IsItCrashing does not log in, bypass authentication, or scan private network targets.
How should I use the scan results?
Start with failed pages, group them by error type, and fix high-value paths first, such as signup, checkout, pricing, documentation, support pages, and indexed SEO pages.
