Start free and scale as you grow. No hidden fees, no surprise charges.
Yes. The Free plan gives you real uptime monitoring, alerts, and a public status page with no time limit and no credit card required. You only upgrade when you need more apps, faster check intervals, SMS alerts, or custom domains.
No. You can create an account and start monitoring on the Free plan with just an email. A payment method is only required when you upgrade to a paid plan.
Free covers basic monitoring with a hosted status page at status.sentrawatch.com/your-slug. Starter adds faster check intervals, more apps and checks, custom domains for your status page, and team members — what most small SaaS teams need once they go live.
Yes. Custom domains are available from the Starter plan and up. You add a CNAME in your DNS, verify, and SentraWatch handles the SSL certificate automatically.
On Pro and Business plans we send SMS to verified phone numbers whenever a check fails or recovers. SMS is included — no per-message add-on fees on the standard tier usage.
Yes. Cancel from the Billing page in your dashboard. You keep paid features until the end of the billing period, then drop to the Free plan — nothing gets deleted.
Paid plans bill monthly by default. Reach out if you're a YC/indie hacker / early-stage startup — happy to work out discounts or extended free usage while you find your feet.
Checks beyond your plan limit simply aren't created. You'll see an upgrade prompt in the dashboard. We don't quietly bill you overage fees or silently drop existing checks.
