Kuvasz Uptime vs Uptrends

Kuvasz Uptime is free, open-source, self-hosted monitoring software for uptime, SSL certificates, keywords, servers, and infrastructure checks. HTTP monitors support adjustable intervals, headers, keyword matching, expected status codes, and response-time checks. Other monitor types include SSL certificate, push, ICMP ping, TCP port, and DNS monitoring. You can create public or private brandable status pages and schedule maintenance windows manually, by recurring cron schedule, or as one-off events to pause affected checks. Notifications can use email, Slack, Discord, Telegram, Microsoft Teams, Apprise, Pushover, PagerDuty, or custom webhooks, configured per monitor. Metrics export to Prometheus or OTLP-compatible tools, and an official Home Assistant integration is available. Monitors can be managed through the Web UI, REST API, or YAML. Deployment uses Docker, Docker Compose, or an official Helm chart and requires PostgreSQL; PostgreSQL 14 is the minimum tested version listed. The Free plan costs nothing, with the monitor limit not stated.

Uptrends monitors websites, web applications, APIs and servers for availability and performance. Synthetic checks run from more than 230 ISP-based locations, with private locations also available. Monitor types include uptime, browser, transaction and API checks; customers allocate monitoring credits across types, and credits do not expire during the annual term. The service supports HTTP/HTTPS, SMTP, POP3, IMAP, Ping, DNS, FTP, Connect, SQL and MySQL. It can automate multi-step checks for identity-driven journeys using SSO or MFA. Alerts can go through email, SMS/text, phone/voice, mobile push, messaging and incident platforms, webhooks or the API. iOS and Android apps show monitoring data and can send push notifications. Core costs $42 a month with annual billing and includes 10 users, US and EU checkpoint regions, uptime checks every two minutes, browser checks every 15 minutes, ticket support and 180 days of data retention.
