Add-ons

Power up your monitoring

Add-ons extend the capabilities of individual domains. Each add-on is priced at +$1 per domain per month and can be toggled on or off at any time.

Frequent Monitoring

+$1 / domain / month

By default, domains are checked every hour. The Frequent Monitoring add-on lets you mark up to 50 Priority Hosts for checks every 5 minutes.

What changes with this add-on

Priority Hosts keep the default hourly schedule for the rest of the domain intact while giving your most critical hosts a faster 5-minute cadence. Manual checks still include every host.

When to use this

Frequent Monitoring is ideal for production infrastructure where DNS changes carry high risk — payment systems, authentication endpoints, API gateways, or any service where a rogue change could cause a significant outage. The shorter the interval, the sooner you'll know.

How to enable

  1. Open a domain and click Settings.
  2. Toggle Frequent Monitoring on.
  3. Return to the domain page and mark the hosts you want as Priority.
  4. Those hosts start using the 5-minute cadence immediately.

Disabling the add-on reverts all hosts to the default hourly check schedule while preserving any Priority Host flags. Billing adjusts automatically at the next billing cycle.

Smart Alerts

+$1 / domain / month

By default, DNS change alerts are sent to the email address associated with your account. Smart Alerts lets you route those notifications to additional destinations on a per-domain basis.

Supported channels

Slack webhook

Post alerts to any Slack channel using an Incoming Webhook URL. The message includes the domain, host, record type, change type, and old/new values.

Additional email addresses

Send alerts to one or more additional email recipients — for example, a team alias or an on-call distribution list — in addition to the account owner.

Note

Your account email always receives alerts regardless of whether Smart Alerts is enabled. Smart Alerts adds destinations on top of the default notification.

How to enable

  1. Open a domain and click Settings.
  2. Toggle Smart Alerts on.
  3. Add a Slack webhook URL, one or more email addresses, or both.
  4. Save. Future alerts for this domain will be delivered to all configured channels.

Setting up a Slack webhook

  1. In Slack, go to Apps and search for Incoming Webhooks.
  2. Click Add to Slack and choose the channel to post to.
  3. Copy the generated Webhook URL.
  4. Paste it into the Smart Alerts configuration for your domain.

Mixing add-ons

Add-ons are independent and can be combined. You can enable Frequent Monitoring, Smart Alerts, or both on the same domain. They can also be configured differently across your domains — for example, enabling frequent checks only for critical domains and Smart Alerts only for domains with a team that needs to know about changes.
