Kuvasz Uptime vs SolidPing

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.

SolidPing is an open-source uptime monitoring platform available as hosted cloud software or self-hosted software. It offers 40 check types, including HTTP, TCP, DNS, databases, email servers, Docker, Kubernetes, headless-browser and custom JavaScript checks, with intervals as frequent as every 10 seconds. The product lists monitoring from six locations, server monitoring and SSL expiry alerts. Alerts can reach a wide range of chat services, email, webhooks, PagerDuty, push services, SMS or voice through Twilio. Rotation schedules, overrides, iCal feeds and multi-step escalation policies are included even on Free. Public status pages can show sections, subscribers, incident updates, uptime and response-time metrics; custom domains are metered by plan. SolidPing also offers a REST API and MCP endpoint. The self-hosted version is a Go binary using SQLite or PostgreSQL, licensed under AGPL-3.0. Hosted plans run from Free to Scale, and hosted account, monitoring and incident data and backups are stored in France on OVHcloud. SolidPing states it does not currently hold ISO 27001 or SOC 2 certification.
