Domnr vs UptimeRobot: the domain-aware alternative
UptimeRobot is one of the most popular uptime monitors, and its free tier is genuinely hard to beat. This is an honest, spec-by-spec comparison — where UptimeRobot leads, where Domnr does, and how to move if uptime is only part of what you need to watch.
Try Domnr freeOn uptime, head to head
On core uptime, Domnr holds its own: HTTP/HTTPS and TCP checks down to 30-second intervals on Growth and Business (60s on Pro), keyword/response assertions, and incidents that open and resolve automatically. Where UptimeRobot pulls ahead is the free tier (50 monitors vs Domnr’s 3) and the breadth of built-in alert integrations. Where Domnr pulls ahead is everything around the uptime check — renewals, DNS, WHOIS, and SSL for the whole domain, not just whether the URL responds.

Where UptimeRobot wins
A free tier that’s hard to beat
UptimeRobot’s free plan gives you 50 monitors at 5-minute checks. If all you need is up/down monitoring for a lot of endpoints at zero cost, that’s more generous than Domnr’s free tier (3 monitors).
More built-in alert integrations
UptimeRobot ships direct integrations for Slack, MS Teams, Telegram, Discord, PagerDuty, voice calls, and webhooks. Domnr today alerts by email on every plan and SMS as a Pro+ add-on — fewer destinations out of the box.
Hosted status pages and more check types
UptimeRobot offers public status pages and a wider set of check types (ping, port, cron/heartbeat). If those are core to your workflow, it’s the more mature fit.
Where Domnr wins
One panel for the whole domain lifecycle
Domnr unifies your domain portfolio, WHOIS/expiry, DNS change tracking, SSL, and uptime in a single dashboard — not just the up/down slice.
Renewal & expiry tracking across registrars
Domnr tracks WHOIS expiry, registrar lock, and auto-renew for every domain you own, across registrars — checked as often as every 15 minutes on Growth and every 5 minutes on Business.
DNS & WHOIS change detection
Domnr snapshots DNS and WHOIS and alerts you when records, nameservers, or registrar status change — not something ping-based uptime tools do.
A 0–100 domain health score
Every portfolio domain gets a health score rolled up from SSL validity, WHOIS expiry, DNS health, registrar lock, auto-renew, and uptime — one number that tells you what needs attention.
Switching from UptimeRobot
- Export your monitored URLs from UptimeRobot (Dashboard → My Monitors), or just copy the list — there are usually only a handful that matter.
- In Domnr, add each URL as an HTTP/HTTPS (or TCP) uptime monitor and set the interval your plan allows (down to 30s on Growth/Business).
- Add the parent domains to your portfolio so Domnr also watches WHOIS expiry, registrar lock, DNS changes, and SSL — the parts UptimeRobot doesn’t cover.
- Point notifications at email (and SMS on Pro+), then decommission the UptimeRobot monitors once Domnr has a clean baseline. Nothing is transferred — Domnr reads public data, so there’s no DNS cutover.
Which should you choose?
If you need free up/down monitoring for many endpoints, hosted status pages, or chat/PagerDuty alerting today, UptimeRobot is the focused, capable pick. If your real job is keeping a portfolio of domains healthy — renewals, DNS, WHOIS, SSL, and uptime together — Domnr covers all of it in one dashboard instead of three tools.
