How Upscanr works

Everything you need to know about checks, retries, keyword rules, alerts, and plan limits.

Uptime checks

Upscanr makes an HTTP GET request to your URL on a schedule you choose: every 15 minutes (Free), every 5 minutes (Pro and Premium), or once per day. We record the HTTP status code, response time, and keyword match result.

A check is marked UP when the server returns a 2xx or 3xx status and any keyword rule you set passes. A check is marked DOWN when the server returns an error status, times out, or the keyword rule fails.

All timestamps on your dashboard and in alert emails use the Europe/Oslo timezone.

Retry logic and downtime alerts

When a check fails, Upscanr does not alert you immediately. Instead it retries on a faster cadence to filter out transient blips:

A down alert is sent after the first confirmed failure (one failed check before the first retry round). A recovery alert is sent as soon as a check passes again.

You can toggle down and recovery alerts independently when setting up or editing a monitor.

Keyword rules

Keyword rules let you catch broken flows where the page still returns HTTP 200 but the expected content is missing — for example, a checkout page that renders an error message instead of the confirmation copy.

HTTP onlyCheck response status only. No keyword required.
Alert if keyword is missingFails if the response body does not contain the keyword.
Alert if keyword appearsFails if the response body does contain the keyword.

Keyword matching runs against the raw response body (HTML included). Case-sensitive matching is optional.

Alert emails

By default, alerts go to the email address you registered with. You can override this per monitor by entering one or more addresses in the alert emails field.

Alert emails count toward your monthly email quota. Free accounts get 50 alert emails per month; Pro gets 200; Premium gets 1 000.

First check on save

When you save a new monitor, Upscanr runs the first check immediately — before the first scheduled interval. The result (UP/DOWN, response time, next scheduled check) appears in the form as soon as the check completes, usually within 5 seconds.

Plan limits

Free3 monitors · 15-minute checks · 1 recipient · 50 emails/month
Pro – $15/mo10 monitors · 5-minute checks · 1 recipient · 200 emails/month
Premium – $29/mo50 monitors · 5-minute checks · 10 recipients · 1 000 emails/month

Limits are enforced at save time. Existing monitors are not deleted if you downgrade, but you won’t be able to add new ones beyond your plan’s cap.
