Glances vs Healthchecks.io
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.
Healthchecks.io is a cron job monitoring service that flips the usual uptime-check model: instead of pinging your server, your scheduled job pings a unique URL Healthchecks.io generates for it, and the service alerts you if that ping doesn't arrive within an expected period and grace time. It's been operating since 2015 and supports cron expressions for defining exactly when a job is expected to run. The service integrates with more than 30 platforms for notifications and incident management, including Slack, Discord, Telegram, Microsoft Teams, PagerDuty, Opsgenie, email, SMS, and generic webhooks, plus GitHub Issues and Prometheus. It offers a free tier for monitoring up to 20 cron jobs with no credit card required, along with paid tiers for more checks, and the project is also open source and self-hostable.
