Glances vs Sysdig
Side-by-side comparison of features, pricing, ratings, and alternatives.
Glances is an open‑source, cross‑platform monitoring tool that provides a concise, real‑time view of system resources such as CPU, memory, disk I/O, network, and processes. It runs on Linux, Windows, macOS and can be accessed via a web interface, making it ideal for both local and remote monitoring. Designed for system administrators and DevOps teams, Glances aggregates metrics into a single dashboard, supports customizable alerts, and integrates with scripts or APIs for automated workflows. Its lightweight design ensures minimal overhead while delivering comprehensive performance insights.
Sysdig is a cloud security and monitoring platform built around real-time runtime intelligence, capturing live system calls at the kernel level to detect threats across containers, Kubernetes, cloud identities, and workloads. It combines a Cloud-Native Application Protection Platform (CNAPP) with AI-driven agents that can investigate and respond to threats in seconds rather than hours.
- Fully open‑source and free
- Runs on all major operating systems
- Lightweight with low resource overhead
- Extensible via plugins and API
- Kernel-level runtime visibility is a strong technical differentiator
- Broad multi-cloud and Kubernetes support
- AI-assisted investigation speeds up incident response
- Established threat research team backing detections
- No native mobile app
- Limited built‑in visualization compared to commercial tools
- Alerting requires manual configuration or external scripts
- Pricing is not public, requires contacting sales
- Aimed squarely at security/DevOps teams running container infrastructure, not general users
- Feature depth means a learning curve for smaller teams
