Monitor
Website monitoring for SaaS tools. The signup page that decides launch day.
A SaaS website has three URLs that decide revenue: the pricing page, the signup flow, and the login URL. SiteGuardian watches all three on a minute cadence. One alert per failure, before the launch email sends people to a 500.
- Watches your signup flow, login URL, and pricing page.
- Probes every minute on Pro. Fast enough to catch the signup page that broke over a Friday deploy.
- Tight slow threshold on /signup. A slow signup behaves like a broken one.
- Probes from multiple regions. Quiet on CDN blips, loud on real outages.
- SSL expiry alerts on every plan.
How it works
Setup, in three beats.
Step 01
Add the URL a new user types first
Paste the home page, the pricing page, /signup, /login, and any /changelog URL. Set a tight slow threshold on /signup (1.5 seconds is sane) and a tighter one still on /login if you use it as a status signal. SiteGuardian starts probing inside the next minute.
Step 02
Let the watch survive every Friday deploy
SaaS sites deploy weekly, sometimes daily. Most deploys are fine; the ones that aren’t trip a 500 for ten minutes between push and rollback. SiteGuardian’s minute cadence catches the deploy-broken signup page within 60 seconds, not the next morning’s stand-up.
Step 03
Catch the signup outage before the launch email hits
A signup flow that returns 500 at 9 AM on launch day loses the launch. SiteGuardian probes every minute on Pro, so the email reaches the on-call inbox the second the signup page stops answering — well before the launch tweet reaches a phone.
