About

Monitor 200 services at 1 minute intervals all month for only $25. All our plans include unlimited international SMS notifications so your costs are predictable, no matter how many alerts you need. No contracts, cancel at anytime. Our SSL checks verify your HTTPS certificates and our HTTP checks verify your content and the server's reply. Sub-minute intervals (15-seconds) mean you're the first to know when something's not right. Flat-rate plans that include unlimited international SMS notifications and unlimited users. We provide two solutions for on-premise monitoring. Agents allow you to assign our standard checks to run in your private networks, so you can monitor private addresses with interval DNS. Push checks monitor server resources. Our automated and on-demand diagnostic tools will help you quickly troubleshoot why a service is failing. Get MTR or dig results automatically emailed when your service fails. See full HTTP request and response headers.

About

Sentinel is a hosted monitoring service for websites, APIs, and network services. It runs HTTP/HTTPS, JSON/API, keyword, SSL certificate, DNS, domain expiration, ping, TCP port, cron job, and heartbeat checks, with response-time data and public status pages. Checks can run as often as every 15 seconds from 15 locations across six continents, with multi-location confirmation for outage alerts. Teams can receive notifications through email, SMS, Slack, Microsoft Teams, Discord, Telegram, PagerDuty, and webhooks. Sentinel also provides a REST API, command-line tools, a Terraform provider, and an MCP server for automation. A free plan is available, while paid plans start at $14 per month; plans include API access and do not charge per seat. The service is intended for developers, DevOps and SRE teams, and businesses that need to monitor service availability.

Pros & Cons from Real Users

Pros

  • Cheap. Email and SMS alerts. A lot of check for a little price. Can disable all alerts at the same time for maintenance.

Cons

  • Support slow (2-3 days answers). They will suspend your account if your are not happy. Poor design and UI (but you don't really need that).
