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.
