Sentinel pricing is designed for agencies, freelancers and DevOps teams that monitor sites for other people, so the tiers scale by how many endpoints you watch and how fast you want to know. Free covers 10 monitors at a 5-minute interval with no credit card, and includes SSL, DNS, domain and API checks that competitors reserve for paid plans. Starter ($14/month) adds heartbeat and cron monitoring, Slack, Teams and SMS alerts, and 1-minute checks. Pro ($29/month) is the agency plan: 100 monitors, full API with Terraform and AI-assistant access, webhooks, and 10 branded client status pages. Business ($79/month) adds 30-second checks, 300 monitors, PagerDuty, custom-domain status pages, client-ready uptime reports and unlimited teams. Annual billing saves about 20% on every paid plan. Every check runs from four regions on every plan.
