Best DNS Monitoring Tools in 2026

DNS monitoring catches what uptime checks miss.

DNS monitoring catches unauthorized DNS changes and resolution failures. Compare the best DNS monitoring tools — free tiers, record types, and pricing.

DNS monitoring checks that your domain's DNS records are resolving correctly. It catches unauthorized DNS changes, misconfigured records, and propagation issues that HTTP monitoring won't detect — your site might be perfectly healthy, but if DNS is broken, nobody can reach it. DNS issues are among the hardest outages to diagnose because everything looks fine from the server side.

Not every uptime monitor supports DNS monitoring. SurePing, Pingdom, and many others focus on HTTP, ping, port, and SSL checks but don't monitor DNS records directly. The four tools below — UptimeRobot, Better Stack, StatusCake, and Uptime.com — are the mainstream options that include DNS record monitoring.

I compared them across free-tier availability, monitor count, pricing, and how DNS monitoring fits into their broader feature set. Every pricing figure was verified on 3 August 2026 against each vendor's own pricing page.

Which tool is right for you?

UptimeRobot — best for DNS monitoring on the largest free tier

uptimerobot.com

UptimeRobot includes DNS record monitoring on its free tier with 50 free monitors — the largest free tier of any tool on this list that supports DNS. With 20+ native integrations (Slack, Discord, Teams, PagerDuty) and multi-region checks, it's the most mature DNS monitoring option for non-commercial use. You can monitor A, AAAA, MX, CNAME, TXT, and other record types.

The non-commercial restriction on the free tier is the main caveat. If you're monitoring DNS for a business domain, you need a paid plan starting at €13/month. UptimeRobot also defaults to annual billing, so the headline price is lower than the month-to-month cost. It doesn't offer domain expiration monitoring, which StatusCake does.

Best for: non-commercial projects that want DNS monitoring on a large free tier with native integrations and multi-region checks.

Strengths

  • Mature product with a large user base and proven reliability.
  • Wide integration catalog (Slack, Discord, Teams, PagerDuty, etc.).
  • DNS record monitoring included.
  • Mobile apps for iOS and Android.

Weaknesses

  • Free tier restricted to non-commercial use.
  • Localizes pricing — EU visitors pay in EUR at a higher effective rate.
  • Defaults to annual billing; month-to-month is more expensive.
  • Status pages are basic on lower tiers.

Better Stack — best for DNS monitoring tied into incident management

betterstack.com

Better Stack includes DNS record monitoring on its free tier (10 monitors) and ties it into a strong incident management workflow. If a DNS record changes unexpectedly or stops resolving, Better Stack can create an incident, page the on-call person, and track resolution — all within the same platform. Commercial use is allowed on the free tier.

The free tier is small (10 monitors) and paid starts at $24/month for 10 monitors — the most expensive option here for DNS monitoring alone. If you only need DNS alerts (not incident management), UptimeRobot offers more free monitors for non-commercial use, and StatusCake bundles domain expiration monitoring.

Best for: teams who want DNS monitoring tied into incident management and on-call scheduling, with commercial use allowed on the free tier.

Strengths

  • Bundles uptime monitoring, log management, and on-call in one product.
  • Beautiful, modern UI with strong incident management.
  • Built-in status pages with custom domains.
  • Phone call, SMS, email, Slack, and Teams alerts.
  • Multi-region monitoring on paid plans.

Weaknesses

  • Modular pricing — logs and on-call are separate add-ons that add up.
  • Free tier is small (10 monitors, 3-min intervals).
  • On-call and incident management are lighter than dedicated tools.
  • No keyword monitoring on the free tier.

StatusCake — best for DNS and domain expiration monitoring combined

www.statuscake.com

StatusCake pairs DNS record monitoring with domain expiration monitoring — the only tool on this list that bundles both. If you want alerts for both DNS changes and domain registration expiry in one place, StatusCake is the clear choice. It also includes SSL certificate monitoring and page-speed monitoring. Commercial use is allowed on the free tier.

The gaps: no cron job monitoring, no free status pages, and the UI feels dated. The 10-monitor free tier is restrictive compared to UptimeRobot's 50. If you need to monitor many DNS records, the free tier won't stretch far enough.

Best for: teams who want DNS and domain expiration monitoring bundled together, with commercial use allowed on the free tier.

Strengths

  • SSL certificate and domain expiration monitoring included.
  • Page-speed monitoring alongside uptime.
  • Long-established product with a track record.
  • LITESPEED monitoring engine for faster checks on paid tiers.

Weaknesses

  • Status pages are paid only — no free status page.
  • No heartbeat / cron job monitoring.
  • No keyword monitoring on the free tier.
  • UI feels dated compared to newer competitors.
  • Free tier is limited (10 monitors, no status pages).

Uptime.com — best for business-grade DNS monitoring with global coverage

uptime.com

Uptime.com includes DNS record monitoring with 75+ global check locations and a business SLA. It's the most business-grade option on this list, with RUM and transaction monitoring alongside DNS checks. Multi-region DNS checks from 75+ locations give strong confidence that DNS is resolving correctly worldwide.

There's no free tier (trial only) and pricing starts at $20/month for 10 monitors — the most expensive option here for DNS monitoring. There's no cron job monitoring. If you only need DNS monitoring, UptimeRobot or StatusCake are far cheaper. Uptime.com makes sense only if you need the global coverage, RUM, and business SLA alongside DNS.

Best for: business teams who need DNS monitoring with 75+ global locations, RUM, and a business SLA, and have the budget for it.

Strengths

  • 75+ global check locations.
  • Real User Monitoring (RUM) available.
  • Transaction monitoring for multi-step flows.
  • Strong SLA and support for business customers.

Weaknesses

  • No free tier — trial only.
  • Pricing starts higher than most competitors ($20/mo for 10 monitors).
  • No heartbeat / cron job monitoring.
  • Blocks AhrefsBot — harder to research via SEO tools.

Why SurePing

SurePing does not yet offer DNS record monitoring. We support HTTP, keyword, ping, port, SSL, and heartbeat monitoring — but DNS monitoring is not currently available. If DNS monitoring is a must-have for you today, UptimeRobot and StatusCake are the best alternatives, both offering DNS monitoring on their free tiers. Better Stack and Uptime.com also support it.

We're being honest about this gap because pretending otherwise would undermine the rest of this comparison. DNS monitoring is on our roadmap, and we'd rather point you to a tool that does it well today than oversell our current capabilities. If you can wait for DNS monitoring and want the most free monitors for HTTP, ping, port, SSL, and heartbeat checks in the meantime, SurePing's 55-monitor free tier is still the most generous — just don't choose us if DNS is a hard requirement right now.

Frequently asked questions

What is DNS monitoring?

DNS monitoring checks that your domain's DNS records (A, AAAA, MX, CNAME, TXT, etc.) are resolving to the expected values. It catches unauthorized changes, misconfigurations, and propagation issues — problems that HTTP monitoring won't detect because the site itself is healthy, but DNS is broken so nobody can reach it.

Does SurePing support DNS monitoring?

Not yet. SurePing currently supports HTTP, keyword, ping, port, SSL, and heartbeat monitoring. DNS monitoring is on the roadmap. For DNS monitoring today, UptimeRobot and StatusCake offer it on their free tiers, and Better Stack and Uptime.com also support it.

Which DNS monitoring tool has the largest free tier?

UptimeRobot, with 50 free monitors including DNS monitoring — but restricted to non-commercial use. Better Stack and StatusCake each offer 10 free monitors with DNS monitoring and allow commercial use. Uptime.com has no free tier.

What DNS record types can I monitor?

Most DNS monitoring tools — including UptimeRobot, Better Stack, StatusCake, and Uptime.com — support common record types: A, AAAA, MX, CNAME, TXT, NS, and SOA. You specify the expected value and the tool alerts you if the resolved value changes or fails to resolve.

How is DNS monitoring different from HTTP monitoring?

HTTP monitoring checks whether your web server responds to requests — the site is up and serving content. DNS monitoring checks whether your domain resolves to the correct IP address — the domain points where it should. A site can be perfectly healthy but unreachable if DNS is misconfigured, so DNS monitoring catches a class of problems that HTTP monitoring misses entirely.
