DomainWarn

DomainWarn is a domain-monitoring service for web agencies, freelancers and IT providers managing client domains. Its combination of scored checks, change alerts and incident handling suits teams that need more than a record-change feed; solo owners of a handful of domains may find its paid tiers more than they need.

Overview

DomainWarn checks website, email, DNS and domain registration health in a single dashboard. Its 21 checks produce area scores and an overall score, giving teams a quick way to spot weaknesses as well as changes. When records or name servers change, it confirms changes against a second name server and shows before-and-after values. Related problems are grouped into incidents, with reminders and one all-clear when service recovers—a useful way to reduce scattered alerts during a prolonged issue.

Monitoring covers MX, SPF, DMARC and DNS records, as well as name-server health. The service says it aims for 99.5% monthly application availability, subject to exclusions in its terms. It is offered to businesses, not consumers.

Key features

DomainWarn’s strongest fit is operational oversight across client accounts. Resolution checks and nameserver health checks complement record-change alerts, while incident grouping makes recovery easier to follow than a stream of unrelated notifications. Checks run every 30 minutes on the paid-plan summary; the Free plan checks every 15 minutes.

Twenty notification channel types cover common team tools and escalation routes, including email, Slack, Microsoft Teams, Discord, signed webhooks, PagerDuty, Opsgenie and SMS. DNS provider integrations include Cloudflare, Hetzner DNS, IONOS, netcup, INWX and Amazon Route 53 for zone import and supported one-click record creation. WordPress and Shopware extensions and a Chrome extension for checking the current page’s domain broaden access beyond the dashboard.

The REST API uses organization tokens with read or write scopes and has a stated limit of 300 requests per minute. The maker says the site and application are hosted by IONOS in Germany, with encrypted backups in German data centres. The privacy policy says connections use TLS, passwords are hashed with bcrypt, and production access is restricted and logged.

Pricing

The Free plan costs nothing with no expiry. It allows three domains and two members, keeps seven days of history and checks every 15 minutes. That is a sensible way to assess a small client portfolio, but the domain and history caps make it a limited long-term fit for growing agencies.

Freelancer costs €19 a month, billed monthly in advance, and can be cancelled by the end of any month. It covers 25 domains, five members and 30 days of history, a practical step up for an independent professional or a small team. Agency costs €49 a month on the same billing and cancellation terms, with 100 domains, 15 members and 90 days of history for larger client books. Agency Pro costs €99 a month, also billed monthly in advance and cancellable by month-end; its 300-domain and 50-member allowances suit teams that need substantially more capacity, while history remains at 90 days.

All listed plans include priority support. The 14-day trial offers a short evaluation window before a paid commitment. The larger plans raise domain and seat limits, but Agency Pro does not extend history beyond Agency’s 90 days.

Platforms

DomainWarn is available on web, through an API and as an extension. The Chrome extension checks the current page’s domain; WordPress and Shopware extensions are also offered. The API’s read and write scopes make it suitable for teams connecting monitoring with their own workflows, within the 300-requests-per-minute limit.

Who it's for

DomainWarn is best for businesses responsible for multiple client domains that want health scoring, DNS change verification, incident follow-up and a broad choice of alert channels in one service. The Freelancer plan targets an independent operator or small team; Agency and Agency Pro make more sense as domain and seat counts rise. The free tier is most useful for a small portfolio or initial evaluation. It is not aimed at consumers, and teams that need longer than 90 days of history on the largest listed plan should look elsewhere.

Pros and cons

• Pros: Twenty-one checks span website, email, DNS and registration, with area and overall scores that help prioritize attention.
• Pros: Second-name-server confirmation and before-and-after values make record changes more actionable than a bare alert.
• Pros: Incident grouping, reminders and a single recovery all-clear help teams track problems through resolution.
• Pros: The free tier has no expiry, and paid plans can be cancelled by month-end.
• Cons: Free monitoring stops at three domains, two members and seven days of history, so client work can outgrow it quickly.
• Cons: Freelancer retains only 30 days of history; Agency Pro raises capacity but not beyond the 90-day history available on Agency.
• Cons: The stated 30-minute check interval on paid plans is less suitable when teams need very frequent monitoring.

Alternatives

For a broad comparison, browse DNS Monitoring Software. UpGex DNS Monitoring is worth considering for a web-only setup with a lower Pro entry price, though its free tier is limited to six credits a month, a 900-second minimum interval and three days of history. StatusDrift is the better candidate when mobile apps and status pages matter; its free plan includes five monitors, five-minute checks, one status page and 90-day data retention.

DNS Check suits users focused on DNS records, with a free allowance of 10 records and a Professional plan at $8/month or $80/year for 100 records and 90 days of history. DriftWatch is an option for teams seeking five-minute scans and 90-day change history; its Pro plan is $29/mo for 25 domains. ZoneWatcher charges per domain and requires a five-domain minimum, making it an alternative for teams comfortable with a paid-only service and one-year retention.

Visual Sentinel is another freemium alternative with Android, iOS, API and web platforms. DNS Spy may suit buyers who prefer a paid DNS-monitoring service, with its Personal plan at $9/month for up to 10 domains and one year of history. Metric Tower is a free alternative with API, self-hosted and web platforms and a free tier of 10,000 lookups per day.

Verdict

Choose DomainWarn if your business manages multiple client domains and needs health scoring, verified record changes and incident follow-through alongside flexible notifications. The free tier is useful for a small portfolio, while the paid plans scale clearly by domains and seats. Look elsewhere if you need faster checks, more than 90 days of history, or monitoring for personal rather than business use.
