Form Monitoring
Your forms fail silently. Prove they work.
A broken form script means zero leads, zero signups, zero revenue -- while your site looks perfectly fine. Sitewatch detects when form-critical scripts and assets fail, so you fix them before your pipeline dries up.
- Detect broken form scripts that silently kill conversions
- Catch checkout flow failures from missing JS bundles
- Get alerted before leads stop coming in

The silent revenue killer
Forms break while your site stays up
Lead forms that don't submit
A missing JavaScript bundle silently disables your contact form. Visitors fill it out, hit submit, and nothing happens. Your server still returns 200 OK.
Checkout flows that fail
Payment scripts from Stripe, PayPal, or custom handlers can 404 after a deploy or CDN change. Users see a broken checkout while your uptime tool says everything is fine.
Signup flows that break
Authentication scripts, validation libraries, and form handler bundles can all fail independently. Your signup page loads but the actual signup stops working.
Third-party form failures
HubSpot forms, Typeform embeds, reCAPTCHA -- when third-party scripts go down, your forms break. Sitewatch checks every referenced script, internal and external.
Hours of lost revenue
Most teams discover broken forms from customer complaints or empty CRM pipelines. By then the damage is done. Sitewatch catches it within your next check cycle.
Ad spend on broken pages
Running ads to a landing page with a broken form means every click is wasted. Sitewatch verifies that form-critical assets are loading before visitors arrive.

Form failure modes
How forms break without anyone noticing
Script failures
- Form handler scripts returning 404 after deployments
- Validation libraries failing to load from CDN
- Third-party form embeds (HubSpot, Typeform) returning errors
- reCAPTCHA and bot protection scripts going down
Asset delivery issues
- Payment processor scripts (Stripe, PayPal) served with wrong MIME type
- Form CSS missing, leaving inputs unstyled and unusable
- CDN serving error pages instead of form JavaScript bundles
- CORS or redirect issues preventing script execution
How it works
How Sitewatch detects broken forms
Fetch your form pages
Add your landing pages, checkout URLs, and signup flows to Sitewatch. Each page is fetched and its HTML is parsed to discover every script and asset dependency.
Validate form dependencies
Every script, stylesheet, and asset referenced in the page gets a HEAD request. Sitewatch checks HTTP status codes and MIME types to verify each dependency loads correctly.
Confirm with retries
Detected issues go through 2-of-3 retry confirmation. Only persistent failures create an incident -- transient CDN hiccups don't trigger false alerts.
Alert with evidence
When a form-critical script fails, you get a Slack or email alert with the exact asset URL, HTTP status, MIME type, and which page is affected.

Uptime tools cannot see form failures

| Payment processors | Invisible | Stripe, PayPal, custom scripts validated |
| Third-party forms | Outside scope | HubSpot, Typeform embeds checked |
| Post-deploy check | Ping says OK | Full asset verification after deploy |
| Evidence | Up or down | Exact script URL, status, failure type |

FAQ
Frequently asked questions
No. Sitewatch monitors the scripts and assets that forms depend on -- JavaScript bundles, validation libraries, payment processor scripts, and third-party embeds. If the scripts that power your form fail to load, the form cannot work. Sitewatch catches these failures before users encounter them.
Yes. Sitewatch checks every script referenced in your page HTML, including third-party form providers like HubSpot, Typeform, and reCAPTCHA. If any of them return errors or wrong MIME types, you get an alert.
Uptime tools ping your server and check for a 200 response. Your form page can return 200 while every script that powers the form is broken. Sitewatch checks what actually loads on the page -- every JavaScript bundle, every third-party dependency.
Checks run as often as every 5 minutes on Pro, or every 30 minutes on Free. You can also trigger on-demand checks after deploys using the dashboard or deploy hooks. Alerts go to your configured channels the moment a confirmed incident is detected.
If a cookie consent script fails to load and that prevents form scripts from initializing, Sitewatch detects the broken consent script. This is a common cause of "form works in development but breaks in production" issues.
