Checkmate vs TLDTrack

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.

TLDTrack gives agencies and web teams a dashboard for website uptime, SSL, DNS, content and brand changes, security, and email health. It checks sites every five minutes and increases checks to every minute during the first hour of an outage. Content monitoring can flag missing keywords or broken links; visual checks can detect pixel-level or price changes. Scheduled AI search visibility checks look for mentions or links from ChatGPT, Claude, Gemini and Perplexity, with alerts when a phrase drops out. Security scans cover ports, TLS, Nuclei vulnerability templates, WordPress checks and OWASP ZAP; full scans add subdomain discovery and active web app scanning. Email checks cover SPF, DKIM, DMARC and MX records and provide a score out of 100. iOS and Android apps provide alerts and monitoring triage, while the Chrome extension offers page notes and visual monitors. A free plan includes one website and four extra monitors; paid plans are billed monthly, with annual billing not yet available. The maker lists a seven-day trial.
