Check Your Website After Every Deployment
A post-deployment website check catches broken routes, failed assets, and server errors before users do. IsItCrashing automates this in under a minute — paste your URL and get a full report.
Free first-pass scan
Check your website for broken pages
Paste a public URL into IsItCrashing and scan discovered pages for failed responses, blank pages, broken assets, and website health issues.
Quick answer
To check your website after a deployment, enter your URL in IsItCrashing. The scanner discovers internal pages from your sitemap and links, checks each one for broken routes, server errors, blank pages, and failed assets, then gives you a sorted report in under a minute — no install, no account, free.
Why post-deployment checks matter
Deployments are the most common cause of unexpected website breakage. Even with staging environments and automated tests, production deployments can fail in ways that tests miss: environment-specific configuration errors, CDN caching issues, database migration problems, and routing changes that silently break existing URLs.
A post-deployment website check catches these issues in seconds rather than hours. Without one, the first signal of a problem is often a user complaint, a support ticket, or a drop in analytics — all far more expensive to deal with than a five-minute scan.
What to check after a deployment
- Homepage and main navigation pages: confirm routing still works end-to-end.
- Conversion pages: checkout, signup, pricing, contact, and demo request forms.
- Recently changed pages: any route affected by the deployment.
- Redirects: confirm old URLs redirect correctly to new destinations.
- Critical assets: JavaScript bundles, CSS, and images that could break on a CDN cache flush.
- API-dependent pages: pages that render data from a backend that may have changed.
How IsItCrashing fits into your deploy workflow
Instead of manually clicking through your site after each deploy, IsItCrashing runs an automated scan across all your discovered public pages. It reads your sitemap.xml, follows internal links, and checks each page concurrently — giving you a complete report instead of a spot check on whatever you remember to click.
The scan takes under a minute for most sites and requires nothing beyond a public URL. No agents to install, no tokens to configure, no dashboards to log into. Paste the URL, start the scan, share the PDF if you need a record.
Building a deployment checklist
A minimal post-deployment checklist should include: run IsItCrashing on the production URL, check any error monitoring dashboards for new spikes, verify the most critical user journeys manually (login, purchase, key CTA), and confirm analytics and tracking are still firing.
For teams shipping multiple times per day, running a scan from a shared checklist link or pasting the URL into IsItCrashing before marking a deploy complete saves time and creates an automatic health record. The PDF export is useful for documenting each deployment's state.
What to do when the scan finds failures
If the scan finds 500 server errors, check your application logs and error tracking immediately — these are backend crashes that need a fix or a rollback. If it finds 404 errors on pages that existed before the deployment, you likely have a routing regression or a missing redirect.
Blank page failures usually indicate a JavaScript hydration problem or a silent server-side rendering exception. These are harder to diagnose but the page URL and error message in the Inspect panel give you a concrete starting point for reproduction.
Manual spot check vs automated scan
Manual post-deployment spot checks are fast but incomplete — you check the pages you remember, not the pages that broke. IsItCrashing scans all discovered public pages automatically, catching broken routes and failed assets you would never think to check manually after a fast-moving deploy.
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, create an account, or add code to your site.
How long does a scan take?
Most scans complete in under a minute. The exact time depends on how many pages are discovered and how fast each page responds. A site with 60 pages typically scans in 20–45 seconds because pages are checked concurrently, not one by one.
How many pages does it scan?
The scanner discovers up to 60 internal pages per scan from your sitemap and internal links. It checks the most important pages first based on sitemap priority and crawl depth. Very large sites with hundreds of pages may need a dedicated crawl tool for full coverage.
How is it different from Down Detector?
Down Detector collects crowd-sourced outage reports for major third-party services like Netflix, Twitter, and banks. It tells you whether a big public service is down for everyone. IsItCrashing scans your own website's internal pages using an automated crawler — it tells you which of your pages are broken and exactly why. They answer completely different questions.
Can I check my website after a deployment?
Yes, that is one of the most common use cases. After a deployment, migration, redirect change, or CMS update, paste your production URL into IsItCrashing and run a scan. You get a full report of working and failed pages in under a minute, so you can catch regressions before users do.
Is this the same as an uptime checker?
No. A basic uptime checker usually tests one URL and alerts you after your homepage goes down. IsItCrashing discovers internal pages and reports specific failed pages, blank responses, broken critical assets, and browser crashes when browser checks are available — across all discovered URLs, not just one.
What does the scanner check?
The scanner checks discovered public pages for HTTP 404 and 500 errors, timeouts, redirect loops, blank content where visible HTML does not load, broken critical scripts or stylesheets, failed important requests, and JavaScript crash signals when browser scanning is configured.
What is a blank page error?
A blank page error occurs when a URL returns an HTTP 200 OK status (meaning the server responded) but the page renders no visible content. This usually means a JavaScript hydration failure, a silent server-side rendering exception, or an empty template was served. These are easy to miss because the server reports success even though the user sees nothing.
Can I export or share the scan results?
Yes. Once a scan completes, click the Export PDF button. This opens the browser print dialog with a print-optimized version of the full report — all failed pages, working pages, and diagnostic details. Save it as a PDF to share with your team or include in a client handoff document.
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. For ongoing JavaScript error tracking, use a dedicated error monitoring service.
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. It is most useful for catching route-level failures and asset errors quickly, not for comprehensive functional testing.
Does it check broken links?
IsItCrashing checks whether your own internal pages load correctly, not whether external links on those pages are valid. It detects internal pages that return 404, 500, or blank responses — which covers the most impactful class of broken page. For external link validation, a dedicated link checker is a better fit.
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. Any team that ships changes to a public website benefits from a fast automated first-pass before users or search engines encounter problems.
Can I scan private staging websites?
Yes, if the staging website is publicly reachable over HTTPS and protected with HTTP Basic Auth. Enable Basic Auth below the URL field and enter the username and password. The credentials are used only for that scan, sent only to the submitted website origin, and are not stored or included in analytics or reports. Login forms, SSO, VPN-only sites, and IP allowlists are not supported.
Should I still use monitoring?
Yes. Use IsItCrashing for fast proactive scans before and after changes, then use a monitoring service for ongoing production visibility and alerting. The two tools complement each other — IsItCrashing catches issues at deployment time, monitoring catches issues that emerge later in production.
