| Fact | Uptime Cairn | Visual Sentinel |
|---|---|---|
| API | The product provides a REST API that can script the actions available in the interface. | The public REST API uses scoped organization keys and exposes monitors, incidents, status pages, maintenance windows, reports, notification channels and servers. |
| Intended users | The site describes it as a fit for people who self-host, want data on their own infrastructure, or need a write API and branded status pages. | The maker describes the product as serving small teams, agencies, and site owners. |
| Purpose | Uptime Cairn monitors websites and servers and tells you when they go down. | Visual Sentinel monitors websites and servers and detects visual page changes that ordinary uptime checks may miss. |
| Security | The site says the Docker Compose reference includes a read-only root filesystem, no-new-privileges, and a healthcheck; it also says the default port binds to 127.0.0.1 and recommends a reverse proxy before internet exposure. | The privacy policy states that data is encrypted in transit with TLS 1.3 and sensitive integration credentials and API tokens are encrypted at rest with AES-256-GCM. |
