Paste up to 10 URLs. Get HTTP status, response time, redirects and SSL certificate expiry for each — instantly, free, no account. Then let DeskUptime keep watching them daily.
Run a check now See DeskUptime →One URL per line. Everything is checked live — nothing is stored.
Prefer the terminal? The same checks from the open-source CLI:
npx github:mahope/deskuptime check https://example.com https://www.wikipedia.org
This tells you how your sites look right now. It can't tell you when one goes down next week.
The failure you don't check for is the one that ships. A monitor runs whether or not you think about it.
A bulk check is silent. DeskUptime notifies you the moment a status, latency or certificate crosses its threshold.
Monitoring services charge $7–$15/month forever. DeskUptime is $19 once and runs on your machine.

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