Customers shouldn't be the ones telling you the site is down.
Every minute of unnoticed downtime costs you revenue, support tickets, and trust. The big monitoring suites are overkill for most teams — and the free ones go silent right when you need them.
You hear it from a customer.
A bug bounty, a tweet, an angry email. By the time you check, it's been broken for 40 minutes.
Your monitor stopped monitoring.
Free tools quietly stop pinging when you exceed the limit, get marked spam, or the project shuts down.
You can't tell what failed.
A 502 looks the same as a timeout looks the same as a missing keyword. You're left guessing.
Add a URL. Get peace of mind.

Paste a URL
Add a public HTTP(S) endpoint. Pick the check interval and what status codes count as healthy.
- 2
We probe it 24/7
Every interval, our worker hits your endpoint, records the status, and stores the response time.
- 3
You get an email
Down → red email. Up again → green email. With duration, status code, and a link to the chart.
Just the monitoring bits. None of the bloat.
HTTP & HTTPS checks
GET, HEAD, or POST. Configurable status code range and per-monitor timeout.
Keyword matching
Verify the response body contains (or doesn't contain) the text that proves the page actually rendered.
1-minute checks
Pro and Business plans probe every minute, so a five-minute outage isn't a five-minute mystery.
Email alerts
Inbox-first alerts on down and recovery. Configurable failure threshold to suppress flaky one-offs.
History & charts
Per-monitor uptime %, response time chart, and an incident log. Up to 1 year on Business.
Read-only credentials
We never store your creds. SitePulse only reads what your endpoint chooses to return.
Cheaper than the cost of one missed outage.
Free forever for hobby use. Upgrade when you outgrow it.
Frequently asked questions
How quickly will I get an alert when something breaks?+
On Pro and Business, monitors are checked every minute and you get an email within seconds of the failure threshold being hit. By default that's the very first failed check.
Where do you check from?+
Today, checks run from a single region (Vercel's default). Multi-region voting is on the roadmap to suppress single-network false positives.
Will you alert me if YOUR system goes down?+
We're transparent about it: a single-region MVP can have blind spots. We log every check, surface 'no data' periods on the chart, and treat resilience as a top priority.
Can I monitor a private endpoint?+
Not yet. Today we only check publicly reachable HTTP(S) URLs. If your service requires auth, expose a dedicated `/health` endpoint that doesn't.
Do you have a status page feature?+
Coming soon. The MVP focuses on the core loop: detect, alert, debug. Public status pages are next.
