Beszel vs Checkmate

Beszel is a free, open-source server monitoring hub built in Go for a tiny resource footprint, with an agent that uses only about 10-15MB of RAM per monitored system. The hub, built on PocketBase, gives a central dashboard for viewing CPU, memory, disk, network, and temperature history, while agents communicate over a minimal SSH connection with no need to expose systems publicly. It tracks Docker and Podman container resource usage individually, sends configurable alerts for CPU, memory, disk, bandwidth, temperature, and status changes, supports multi-user access with OAuth/OIDC login, and includes automatic backups plus a REST API out of the box.

Checkmate is an open-source, self-hosted tool designed to track and monitor server hardware, uptime, response times, and incidents in real-time with beautiful visualizations. It provides a comprehensive overview of server performance and helps teams identify and resolve issues quickly.

• Built-in REST API and automatic backups included by default

• Real-time monitoring and tracking
• Customizable dashboards and workflows
• Open-source and self-hosted for flexibility
• Scalable and extensible architecture

• Primarily designed for Linux hosts; Windows support relies on community forks
• Smaller ecosystem and plugin library than established tools like Zabbix or Netdata
• Alerting is simpler and less feature-rich than dedicated enterprise monitoring platforms

• Steep learning curve for non-technical users
• Limited support options for non-community users
• Requires technical expertise for customization
