Compare Monitoring Approaches

Not necessarily. Sitewatch catches a different class of failures -- the ones where your server responds normally but the page is broken for users. Many teams run both: uptime monitoring for server availability and sub-minute response checks, Sitewatch for asset verification, MIME validation, and page fingerprinting.

Error tracking tools like Sentry catch JavaScript exceptions after they happen in a user's browser. Sitewatch detects problems before users encounter them -- a missing JS bundle, a stylesheet served with the wrong MIME type, a redirect loop -- by checking from outside your infrastructure on a daily schedule plus on-demand.

APM tools monitor server-side performance, database queries, and request traces. They do not check if your frontend assets actually load or if a CDN is serving files with the wrong content type. Sitewatch fills this gap by validating the user-facing result -- the page and every asset it depends on.

Sitewatch replaces basic uptime checkers for teams that need to know more than "is the server on." It does not replace APM, logging, or error tracking. It covers the frontend and asset layer -- the part of your stack where silent failures live and where uptime tools have a structural blind spot.

Start with what actually breaks. If your team regularly discovers broken deploys, missing assets, or client-facing failures after customers report them, website monitoring should be your next addition. If server-side errors and latency are your main problems, APM comes first. Most teams eventually need both layers.
