Know when it breaks. Before your customers do
Monitor HTTP endpoints, SSL certificates, and domain expirations. Get alerted via email, SMS, phone call, or webhook the moment something needs attention.
Endpoint monitoring with the details that matter.
Monitor any HTTP or HTTPS endpoint. Check status codes, measure response times, detect keywords in response bodies, and get alerted when anything drifts from expected behavior.
- Custom HTTP methods, headers, and expected status codes
- Response time measurement with timeout detection
- Keyword presence or absence detection in response body
Four monitor types. Four alert channels
Email alerts
Get notified by email when a monitor detects an issue. Configurable per monitor with smart deduplication to prevent alert storms.
SMS & phone call alerts
For critical monitors — get a text message or an actual phone call when something goes down. Because some incidents can not wait for you to check email.
Webhook notifications
Push alerts to any HTTP endpoint. Custom headers supported. Integrate with Slack, Discord, PagerDuty, or your own internal tooling.
Alert deduplication
PulseCheck tracks what was already sent and suppresses duplicate notifications. No alert storms, no notification fatigue — just the alerts that matter.
Status pages · coming soon
Public and branded status pages for your customers. Custom domains and custom styling. Coming soon.
Four channels. Zero noise
Every monitor can notify through any combination of email, SMS, phone calls, and webhooks. Smart deduplication prevents alert fatigue — you only hear about what matters.
Email & webhooks
The basics covered. Email for humans, webhooks for your toolchain. Custom headers on webhooks for authentication with third-party services.
SMS & phone calls
For incidents that cannot wait. Get a text or an actual phone call the moment a critical monitor fires. Because some alerts need to interrupt.
Smart deduplication
Same incident, same monitor — one notification. PulseCheck tracks what was sent and suppresses duplicates automatically.
Pay per check. Free tier included
Every check type has a generous free tier. Notifications are priced by channel — email and webhooks are nearly free, SMS and calls cost what they cost us.
Each scheduled check counts as one unit. A monitor checking every 60 seconds = ~43,200 checks/month. The free tier covers roughly 2 monitors at 1-minute intervals.
Built for teams that cannot afford downtime
SaaS platforms
Monitor your API endpoints, track SSL certificates, and get alerted the moment latency spikes or a certificate is about to expire.
Agencies managing clients
Monitor all your client websites from one account. SSL and domain expiry alerts ensure nothing lapses on your watch.
E-commerce
Every minute of downtime costs revenue. Monitor your storefront, payment endpoints, and checkout flow — get a phone call if checkout goes down.
Infrastructure teams
HTTP checks for services, SSL monitoring for certificates, domain tracking for your portfolio. One tool instead of three.
Compliance & security
Track SSL certificate expirations and domain registrations. Never let a certificate lapse or a domain expire because someone forgot to renew.
Startups & side projects
The free tier covers 2+ monitors at 1-minute intervals plus 2,000 email alerts. Monitor your production app at zero cost.
