Checkmate vs StatusDrift

Checkmate is a free, open-source, self-hosted dashboard for monitoring infrastructure, service uptime, PageSpeed, and incidents. It checks HTTP, ping, TCP, gRPC, WebSocket, DNS, SSL, and more than 100 game server types. Its Capture agent reports server CPU, memory, disk, temperature, and network metrics, while PageSpeed monitoring tracks Lighthouse scores and Core Web Vitals over time. Public status dashboards can show per-service uptime and incident history with custom branding. Alerts can go to email, Slack, Discord, Telegram, Twilio SMS, Pushover, ntfy, Matrix, Rocket.Chat, PagerDuty, Microsoft Teams, and webhooks. The maker says metrics, logs, incidents, and user accounts remain in the database configured by the operator, with no phone-home or telemetry pipeline. Checkmate is licensed under AGPL-3.0 and can be installed with Docker Compose or Kubernetes/Helm; its image runs on x86, Apple Silicon, and Raspberry Pi. The maker says the API accepts JSON for bulk monitor setup and provides a REST API reference. The free plan includes all features, no monitor limits, self-hosting, and 12 alert channels. There is no one-click migration import or paid support tier.

StatusDrift combines uptime monitoring, status pages, and incident management. It monitors websites, APIs, SSL certificates, DNS and domains, ping, TCP ports, and cron or heartbeat jobs, with checks from multiple regions. Status pages support custom branding and domains, HTTPS, component groups, incident updates, postmortems, uptime history, and password protection. Incident tools include automatic incident creation, escalation policies, on-call schedules, and publishable postmortems. Monitoring intervals vary by plan, from five minutes on Free to 30 seconds on Business. The Free plan costs nothing and includes five monitors, one status page, email, Slack, and webhook notifications, 90 days of retention, audit logs, and community support. Pro is listed at $12,129 a month, billed as $108/year; Business is $292,923 a month, billed as $276/year. The service offers a Terraform provider and REST API, as well as an internal agent for checks on private endpoints without inbound ports. StatusDrift says it does not send SMS or voice calls directly.
