We switched from a competitor and immediately noticed the difference. Alerts are faster, the dashboard is cleaner, and we haven't missed a single outage.

The 30-second setup is real. I added our production APIs during a meeting and was monitoring before the call ended. Absolutely impressed.

Frequently asked questions

Everything you need to know about API Health Check

How does the free plan work?

The free plan includes 3 monitors with 5-minute check intervals, email alerts, and 7-day data retention. It's completely free forever — no credit card required, no trial period, no strings attached. Perfect for personal projects or trying out the service.

What happens when my API goes down?

We immediately verify the outage from multiple locations to avoid false positives. Once confirmed, we send alerts through your configured channels (Slack, email, SMS, PagerDuty, etc.) within seconds. We track the entire incident lifecycle and notify you when service is restored.

Can I upgrade or downgrade at any time?

Absolutely. You can change your plan at any time from your account settings. Upgrades take effect immediately with prorated billing. Downgrades take effect at the end of your current billing cycle to ensure uninterrupted service.

Do you offer annual billing?

Yes! We offer a 20% discount on all annual plans. That's like getting more than 2 months free. Contact our sales team for enterprise annual agreements with custom terms.

Where are your monitoring servers located?

We monitor from 50+ locations across North America, Europe, Asia-Pacific, and South America. This helps us detect regional outages and provide accurate latency data from every continent. You can choose which regions to monitor from.

Is my data secure?

Security is our top priority. We're SOC 2 Type II certified and GDPR compliant. All data is encrypted at rest and in transit using AES-256 and TLS 1.3. We never store your API response bodies — only status codes and latency metrics.
