What does the bulk checker report for each URL?

Final HTTP status code after redirects, total response time in milliseconds, whether the request was redirected, the final destination URL, and SSL certificate expiry days for HTTPS URLs.

Does the bulk URL checker work with any website or only certain platforms?

Any public URL. Checks happen over plain HTTP(S) at the URL level, so WordPress, Shopify, Webflow, Squarespace, static hosts, API endpoints and hand-rolled servers all behave identically.

Is this bulk URL checker really free?

Yes. No account, no email, no limits beyond 10 URLs per run. DeskUptime Pro ($19 one-time) adds scheduled monitoring and desktop alerts for the same URLs.

A snapshot isn't monitoring

This tells you how your sites look right now. It can't tell you when one goes down next week.

You have to remember to run it

The failure you don't check for is the one that ships. A monitor runs whether or not you think about it.

No alerts between checks

A bulk check is silent. DeskUptime notifies you the moment a status, latency or certificate crosses its threshold.

SaaS charges monthly for this

Monitoring services charge $7–$15/month forever. DeskUptime is $19 once and runs on your machine.

FAQ

How many URLs can I check at once?

Up to 10 per run here — paste them one per line. Need more or want it automated? The CLI (npx github:mahope/deskuptime check url1 url2 …) takes any number, and the desktop app monitors your full list on a schedule.

What exactly gets checked?

For each URL: final HTTP status after following redirects, total response time in ms, whether a redirect happened and where it landed, plus SSL certificate expiry date for HTTPS URLs. Nothing is logged or stored.

Does it work with any website or stack?

Yes. These are plain HTTP requests — no agent, plugin or platform integration. WordPress, Shopify, Webflow, static sites and API endpoints all work identically.

Why does an HTTPS URL sometimes miss its SSL expiry?

Certificate dates are read from public certificate-transparency logs. Brand-new certificates or rate-limited lookups can occasionally return nothing — re-run the check and it will usually appear.

Can I check internal or staging URLs?

The web tool only reaches public URLs. The DeskUptime app and CLI check anything your own machine can reach — localhost, intranet hosts, staging domains behind a VPN.
