Netlify monitoring
You Pushed to Netlify. Did Anything Break?
Netlify deploys are atomic and instant. But "deployed successfully" doesn't mean "works correctly." A build plugin can break asset paths, a redirect rule can create a loop, a Netlify Function can timeout returning an empty body, and the CDN can serve a stale deploy. Sitewatch hooks into your Netlify pipeline and validates everything after every push.
- Deploy notifications trigger instant post-deploy checks
- Validates every JS, CSS, and image asset
- Stack-aware diagnosis for Nuxt, Astro, Gatsby, etc.

Netlify-specific failures
What breaks on Netlify that uptime tools miss
Build plugin breaks asset paths
CriticalA Netlify build plugin rewrites or optimizes asset paths incorrectly. HTML references /assets/main.js but the file deployed as /assets/main-abc123.js. The page loads, the app doesn't.
Redirect rule creates loop
CriticalA _redirects or netlify.toml rule conflicts with another rule or a framework-generated redirect. Specific pages enter infinite redirect loops while the homepage works fine.
Functions timeout with empty body
CriticalA Netlify Function hits the 10-second timeout and returns an empty response. The frontend shows a blank section or broken state. The function "responded" — with nothing.
CDN serves stale deploy
ModerateAfter a deploy, some CDN edge nodes still serve the previous deploy's assets. Visitors in certain regions get mismatched HTML/JS combinations. The deploy log shows "published."
Split testing serves broken variant
ModerateNetlify's split testing serves a branch that has a build error or broken feature. A percentage of your traffic sees a broken site. The other percentage sees it working fine.
Form handling failure
ModerateNetlify Forms relies on a specific HTML attribute. A framework rebuild strips the attribute or changes the form structure. Form submissions silently stop working.

How Sitewatch monitors your Netlify site
Netlify deploy hooks
Add a Sitewatch webhook as a Netlify deploy notification. Every successful deploy triggers an instant website check — catch issues in minutes, not hours.
Full asset validation
Every JS bundle, CSS file, image, and third-party script is validated after each deploy. A single broken asset path triggers an alert with the exact file and HTTP status.
Framework detection
Sitewatch detects your framework — Nuxt, Astro, Gatsby, Hugo, Eleventy, Next.js — and provides fix playbooks specific to your stack, not generic advice.
Multi-region checks
Netlify deploys globally. Sitewatch checks from EU and US to catch CDN edge inconsistencies after deploys.
2-minute setup
Set up Netlify monitoring
Add your Netlify site
Enter your production URL. Sitewatch discovers pages and assets automatically. No build plugins or code changes needed.
Add the deploy notification
In Netlify → Site settings → Deploy notifications → add an outgoing webhook pointing to your Sitewatch deploy hook URL.
Push and verify
Deploy your next change. Sitewatch runs a full check and alerts you if any asset broke during the build or deploy process.

Netlify monitoring FAQ
Sitewatch monitors the pages and assets your visitors see. If a Netlify Function renders or serves page content, that output is validated. Sitewatch doesn't monitor Functions directly (execution logs, invocation counts), but catches the user-facing impact of Function failures.
Yes. Sitewatch follows redirect chains during page checks. If a redirect rule creates a loop or redirects to a 404, the affected page is flagged with the redirect chain details.
No. Sitewatch is entirely external — no build plugins, no code changes, no performance impact on your build. Just a deploy notification webhook.
Any framework deployed on Netlify — Nuxt, Astro, Gatsby, Hugo, Eleventy, Next.js, SvelteKit, Remix, and plain HTML. Sitewatch detects your framework automatically for stack-specific diagnosis.
