About PulseWren
PulseWren helps business owners, freelancers and agencies know whether their websites are working — with clear answers instead of technical jargon. Today it offers a free instant checker; automatic monitoring with alerts is coming soon.
How a check works
- Step 1
Address check
We make sure the address is a public website — never a private or internal network.
- Step 2
DNS lookup
We find the website's server, and check every address it points to.
- Step 3
Connection and SSL
We connect, and for https:// sites verify that the certificate is valid, trusted and covers the domain.
- Step 4
First response
We wait for the server's first answer and its HTTP status, then stop — we never download the page.
Limitations
- Each check is a snapshot of a single moment, made from one location.
- Some websites block automated checks (for example with bot protection); they may show as a warning even when visitors can use them.
- We read only the response status and headers — never page content — so we cannot tell whether a page looks right.
- Only public websites on standard web ports (80 and 443) can be checked.
Your privacy
- No account, no tracking and no analytics.
- We don't keep a record of the websites you check: nothing about your checks is written to disk or to our logs. Results are held in memory for 30 seconds so repeated checks are fast.
- To prevent abuse, the server briefly remembers, in memory only, your IP address (for IPv6, its network prefix) for up to 24 hours, and the names and addresses of checked servers for up to one minute. This is used only to apply the limits on checks, is lost whenever the server restarts and is never logged.
- Your recent checks are stored only in your own browser, and you can clear them at any time.
