The same auditors you run by hand, running on their own — and telling you the moment a result changes.
Put the pages you care about in a project. Sites behind basic auth work too.
Turn on any auditor for that URL and choose how often it runs — anywhere from every 3 minutes to once a day.
Send status-change emails to admins only, or to everyone in the organization.
When a scheduled run changes status — pass to fail, or back again — your team gets an email that links straight to that check’s history.
Scheduled monitoring is included in the Monthly Subscription and Enterprise plans. Manual audits are available on every plan. Compare plans →
Every block is one scheduled run of that auditor against our own site, oldest to newest. Same auditors, same alerts, same view you get.
