About SiteInformant

No business should be blindsided by downtime.

SiteInformant is a website and API monitoring platform that tracks uptime, retained p95 response time, deployment impact, and SSL certificate expiration. It routes alerts through named Email, Slack, Discord, Microsoft Teams, and custom webhook destinations.

SiteInformant helps you monitor your website’s uptime, response time, and SSL certificate health 24/7 and alerts you via Email, Slack, Discord, Microsoft Teams, and custom webhooks when something goes wrong. It’s fast to set up, affordable, and API ready so developers and teams can automate workflows and build custom dashboards.

Your website deserves more than luck. It deserves protection.
