Pingdom alternative
Zinn® Uptime and Pingdom compared: free monitoring, transaction checks, SMS alerts and status pages.
The short answer
Pingdom is a bigger, paid toolkit with transaction checks and real-visitor data. Zinn® Uptime is the simple, free way to know the moment your website goes down — with no trial clock and no credit card to start.

Why people choose Zinn® Uptime over Pingdom
One flat price for more websites, shown openly on the pricing page, instead of a calculator of tiers.
Domain expiry and nameserver changes are watched for free, so a lapsed domain cannot take your site down unannounced.
Where they are the better choice
Pingdom offers transaction monitoring that walks through a sign-in or checkout, real user monitoring from actual visitors, SMS alerts, maintenance windows and public status pages. For a team that needs any of those, Pingdom does more.
Where Zinn® Uptime fits
Zinn® Uptime fits when you want to start free, with no trial clock, and pay a flat $9 a month per 10 addresses — with domain expiry monitoring included and everything on the same account as your hosting.
How to switch from Pingdom in three steps
Add the same websites
Create a free account and add each address you watch in Pingdom. Put a word from the page as expected text so a blank or broken page counts as down, not just an error code.
Connect your alerts
Choose where alerts go — email to everyone on the account, a Slack channel, a Telegram chat or a signed webhook — and send a test so you know it arrives.
Run both for a week, then decide
Keep Pingdom running while Zinn® Uptime builds up its own history. When both agree for a week, you can cancel the one you no longer need — nothing here locks you in.
Questions about switching from Pingdom
Can I use Zinn® Uptime and Pingdom at the same time?
Yes. They check your website independently from the outside, so running both side by side changes nothing on your site. Many people do this for a week before they switch.
Is Zinn® Uptime really free, or is it a trial?
It is free for good, not a trial: 3 websites checked every 5 minutes, with every alert channel and free domain expiry watching. More websites and one-minute checks come in packs of 10 for $9 a month.
Does Zinn® Uptime do everything Pingdom does?
No, and the table above says where. Zinn® Uptime does website checks with expected text, confirmed outages and domain watching very well; if you need the extra check types or features marked No, Pingdom may suit you better.
