Checkmate vs ServiceUptime

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.

ServiceUptime remotely monitors website availability and performance, then alerts users when it detects problems. Checks cover web pages, PING, HTTP/HTTPS, links, mail servers, download servers, DNS, MySQL, and custom servers or ports. Monitoring intervals range from 1 to 60 minutes, depending on the selected option and plan. The free account includes one service checked every 30 or 60 minutes. Paid plans list Start at $5.95 a month for three monitors with five-minute checks, Standard at $9.95 a month for six monitors, Advanced at $29.95 a month for three monitors with one-minute checks, and Professional at $89.95 a month for ten monitors with two-minute checks. Alerts can use email, SMS, or webhooks, with an API for custom applications. Detected outages are checked from multiple monitoring locations before alerts are sent. Reports include uptime, performance, lifetime statistics, and public statistics for websites. ServiceUptime was established in 2005. A 14-day trial is listed.
