24/7 monitoring with alerts
We're building automatic monitoring that tells you when your website goes down — before your customers do. Today, PulseWren checks a website whenever you ask.
See the planned plansQuestions
Is it really free?
Yes. The website checker is free to use and needs no sign-up.
What does “Warning” mean?
The website answered, but something needs attention — for example the page wasn't found, access was restricted, or the SSL certificate expires soon.
Does PulseWren watch my website all the time?
Not yet. Today it checks a website when you ask. Continuous monitoring with alerts is coming soon.
Do you store the websites I check?
We don't keep a record of the addresses you check. Results are held in memory for about 30 seconds so repeated checks are fast. Your list of recent checks is stored only in your own browser, and you can clear it at any time.
Why might my site look down here but work for me?
Each check is made from one location at one moment. Network problems, firewalls or bot protection can affect the result. Try again in a minute, or check from another network.
