How signalp.ing works
signalp.ing was born out of one missed festival ticket restock, refreshing a checkout page at 2am and losing the good seats anyway. Now the watching happens for you. Paste a URL, choose a check type, tell us where to send the ping.
Status & uptime
We ping the URL on a schedule and watch for it going down, timing out, or coming back. Good for anything you need to know is alive: a site, an API, your own project.
Part of a page changes
Watch a whole page, or just the one part you care about, like a button, a section, or a status. We tell you the moment it changes.
Keyword appear/disappear
Give us a word or phrase. We ping you the instant it shows up, like "In stock," or the instant it goes away, like "Sold out."
Price tracking
We read the price off the page and keep a short history so you can see the pattern, not just the current number.
Where the ping goes
Phone notification
Instant, straight to your phone. Sent through the Telegram app. Our most popular option.
Reliable, works everywhere, zero setup.
Connect your own tools
For the technically inclined. Send it into Slack, Discord, or your own app.
More channels coming.
Every free account gets one 6-hour boost window a week.
Turn it on and we check that monitor every 30 seconds instead of every 5 minutes, for 6 hours straight. Once the window runs out, that monitor goes back to its normal 5-minute check speed until next week, nothing breaks and nothing gets shut off.
Need boost more than once a week? Top-ups and the paid plan give you more of it, see pricing.
Checking from your own region
Some pages show different content, prices, or availability by region. You can choose which region we poll from, so what you see matches what your monitor sees.
