A release or a plugin update can break markup, styles or scripts in ways nobody notices at first. Validation monitors will check your pages on a schedule and report what broke.
Front-end problems rarely take a site down; they make it quietly worse. A JavaScript error stops a form from submitting on one browser. A stylesheet fails to load and the page renders as plain text. Invalid markup confuses screen readers and search engines.
Validation monitoring will load your pages on a schedule, validate the HTML and CSS, catch JavaScript errors and missing files, and tell you when something new appears.
The plan for the first release. Every check will be stored in a full log, like all Upzilla monitors.
Errors and warnings in the markup.
Invalid rules and stylesheets that fail to load.
Errors thrown while the page loads.
Scripts, styles and images that return errors.
Website Performance can already check how your pages load, element by element.
