For dev teams
CI passed. The deploy completed. Your pricing page just broke.
Your test suite went green. Your deploy hook fired. Somewhere between the CDN and the browser, your checkout page is serving a broken JS bundle. Sitewatch catches what CI can't — the real user experience on your production pages, automatically verified after every deploy.
- Deploy hooks: trigger a Sitewatch scan the moment your deploy completes
- Post-deploy verification reports: before/after asset comparison, pass/fail in under 2 minutes
- Plain-English diagnosis: what broke, which asset, what it means — no log diving required

Deploy hooks
Connect your CI/CD pipeline via webhook. The moment your deploy completes — Vercel, Netlify, GitHub Actions, or any platform — Sitewatch starts scanning production automatically.
Post-deploy verification
Before/after asset comparison runs immediately after your hook fires. Every script, stylesheet, and font fingerprinted. Pass/fail verdict in under 2 minutes — before users ever load the page.
Plain-English diagnosis
Know exactly what broke, which asset failed, and what it means in plain language — no log diving, no digging through CDN dashboards. Fix it in minutes, not hours.
Business severity scoring
Not all breakage is equal. Sitewatch ranks failures by business impact — a broken checkout page fires immediately, a missing blog footer can wait. Prioritize what actually matters.
No test scripts required
Sitewatch discovers and validates every asset on your pages automatically. No Playwright scripts to write, no synthetic user flows to maintain. It just works after every deploy.
Multi-region checks
Catch CDN edge failures that only affect certain regions. A broken bundle served from the wrong CDN edge can affect only specific users — Sitewatch checks from multiple regions to catch it.
Webhooks
Deploy hook support for any CI/CD platform
<2 min
Post-deploy report time

Fits your pipeline
Running in under five minutes
Connect your CI/CD pipeline via deploy hook webhook
Copy the Sitewatch webhook URL and add it as a deploy notification in Vercel, Netlify, GitHub Actions, or any other platform. Takes under a minute.
Deploy fires the hook — Sitewatch starts immediately
The moment your deploy completes, the webhook triggers a full production scan. No polling, no delays — it starts the instant your code goes live.
Every page asset is fetched, typed, and fingerprinted
Sitewatch walks every page you monitor, HEAD-requests every linked asset, checks MIME types, and computes SHA-256 fingerprints to catch content changes.
Pass/fail report lands in Slack/email with diagnosis and diff
Within 2 minutes you get a structured verdict: which assets passed, which failed, what the diff looks like, and plain-English diagnosis for anything that broke.
Ship with confidence.
Know within 2 minutes if your deploy broke something in production.
Why Sitewatch
Your CI went green. That doesn't mean production works.
| Feature | CI/CD testing alone | CI/CD + Sitewatch |
|---|---|---|
| Catches broken CDN assets | Not checked — tests run in CI, not production CDN | Every asset fetched from production CDN after deploy |
| Detects MIME type changes | Silent — tests don't check HTTP headers in production | MIME type validated on every asset, every scan |
| Monitors third-party script outages | Not covered — external scripts bypassed in test env | Every third-party script checked in production |
| Requires writing test scripts | Yes — Playwright, Cypress, or manual scripts needed | No scripts needed — Sitewatch discovers assets automatically |
| Alerts on missing stylesheets | Only if you wrote a test for it | Automatic — every CSS file validated on every scan |
| Catches redirect loops from hosting | Rarely — integration tests miss hosting-layer issues | Detected automatically — redirect chains are traced |
| Plain-English diagnosis | Stack traces and log lines — requires interpretation | Human-readable summary of what broke and what it means |
| Verifies production after every deploy | No — CI passes before deploy; nothing checks after | Yes — deploy hook triggers immediate post-deploy scan |

FAQ
Frequently asked questions
Add the Sitewatch webhook URL as a deploy notification in your CI/CD platform — Vercel, Netlify, GitHub Actions, CircleCI, or any platform that supports outbound webhooks. When your deploy completes, the webhook fires and Sitewatch immediately starts scanning all monitored pages on that site. The scan runs against production, not your CI environment, so it catches real-world CDN and hosting issues.
Yes — Sitewatch complements your existing test suite, it doesn't replace it. CI tests verify your code logic. Sitewatch verifies that production actually works after deploy: assets load, MIME types are correct, CDN delivers the right files, and there are no redirect loops introduced by your hosting platform. The two cover entirely different failure surfaces.
CI tests run in a sandbox before the code reaches production infrastructure. Sitewatch runs after deploy, against real production: broken CDN asset paths, MIME type mismatches served by your host, missing files that were never uploaded, third-party script outages, redirect loops introduced by Vercel/Netlify routing rules, and page fingerprint changes that indicate unintended content modifications.
Sitewatch starts scanning the moment your webhook fires and delivers a full pass/fail report — including plain-English diagnosis for any failures — within 2 minutes for most sites. Larger sites with many monitored pages may take a little longer, but the first critical failures are flagged as soon as they're detected, before the full scan completes.
Yes. Any platform that supports outbound webhooks on deploy completion works with Sitewatch. Vercel and Netlify both support deploy hook URLs natively. GitHub Actions can call the webhook via a curl step at the end of your workflow. The webhook endpoint is documented in your Sitewatch dashboard under site settings.
Sitewatch runs checks from multiple geographic regions, which catches CDN edge failures that only affect users in certain locations. If your CDN serves a stale or broken bundle from one edge but not others, Sitewatch flags the region-specific failure in the report. This is a class of problem that's nearly impossible to catch with CI tests, which run in a single environment.
