Comparison
DropPerch vs UptimeRobot for domain expiry monitoring
UptimeRobot is an excellent uptime monitor that also watches domain expiry. DropPerch only watches domains. Which one fits depends on whether expiry is a side feature for you or the whole job.
The short answer
Choose UptimeRobot if you want uptime, SSL and domain expiry in one dashboard, need alerts in Slack, Teams or by SMS, and are already paying for it. Expiry monitoring comes switched on with every website monitor, so there is nothing extra to set up.
Choose DropPerch if what you actually need to track is a list of domains — including ones with no website behind them, like defensive registrations, redirects and parked names — and you want to know when a domain enters redemption or goes on hold, not only when the date approaches.

| Paid plans | $12/month or $120/year, unlimited domains. Agency $39/month adds a weekly report per client | Solo from $10/month for 10 monitors ($9/month billed annually); Team $41/month for 100 |
| Where expiry data comes from | The registry itself, over RDAP | WHOIS records |
| How often it is re-checked | Every domain, every day | Not published |
| Expiry reminders | 30, 14, 7 and 1 days before expiry | 30, 14 and 7 days before, and on the expiry date |

Where the expiry date comes from
UptimeRobot's own help documentation says it reads the expiration date from WHOIS records, and that some extensions may not be covered because of their WHOIS server rules. WHOIS is the older protocol that ICANN has been retiring for generic TLDs in favour of RDAP since January 2025.
DropPerch asks the registry itself over RDAP — Verisign for .com, PIR for .org, and so on — every day for every domain. The practical difference shows up at the edges: right after a renewal, during a transfer, and in the weeks after expiry, which is when a stale copy is most likely to be wrong.
Dates versus states
An expiry reminder tells you a date is coming. It does not tell you what happened afterwards. A domain can pass its expiry date and sit safely in auto-renew grace, or it can be quietly moved into redemptionPeriod, where getting it back costs a restore fee, and then into pendingDelete, where it cannot be got back at all.
DropPerch emails you when a watched domain enters any of those states, or goes on clientHold — the state where the registrar has pulled it from DNS and the site and email are already down. UptimeRobot's documentation describes reminders before and on the expiry date; it does not describe alerts on registry status changes.
Domains without a website
UptimeRobot attaches expiry monitoring to HTTP and keyword monitors — it watches the domain of a site you are already monitoring. A business holding brand variants, typo domains or old campaign domains that only redirect has a lot of names that are not websites. In DropPerch every domain is simply a row on a list, website or not.
What it costs for 25 and 100 domains
- 25 domains: free on DropPerch for the first 25 accounts, $12/month after that. On UptimeRobot, domain expiry needs a paid plan, and Solo starts at 10 monitors for $10/month, so 25 websites means a larger Solo tier.
- 100 domains: $12/month on DropPerch. UptimeRobot's Team plan is $41/month for 100 monitors — but it also gives you uptime and SSL monitoring on all of them, which DropPerch does not.
So the fair comparison is not price for price. If you need uptime monitoring anyway, UptimeRobot's expiry feature comes along for free. If you only need the domains watched, you are paying for monitoring you will not use.
Where UptimeRobot is the better choice
- You need to know within a minute when a site goes down. DropPerch does not check uptime at all.
- You need SSL certificate expiry alerts. DropPerch does not watch certificates.
- Your team lives in Slack, Teams or PagerDuty. DropPerch alerts by email only.
Plenty of people run both: UptimeRobot for uptime, and DropPerch for the domain list, including the names that never had a site.

Common questions
Does UptimeRobot monitor domain expiration on the free plan?
No. UptimeRobot's help documentation states that domain expiration monitoring is provided on paid plans. DropPerch monitors 25 domains free for the first 25 accounts and 5 after.
Can I use DropPerch and UptimeRobot together?
Yes, and many people do. UptimeRobot watches whether sites are up; DropPerch watches the domain registrations themselves, including domains that have no website.
Is DropPerch an UptimeRobot alternative?
For domain expiry, yes. For uptime monitoring, no — DropPerch does not check whether a website is up, and does not monitor SSL certificates.
Try it on your own domains
DropPerch reads each domain from its registry every day and emails you before it expires, and the moment one goes on hold, into redemption or pending delete. Any registrar, no transfer.
