Healthchecks.io
Healthchecks.io is a simple and effective cron job monitoring tool that alerts users when their scheduled tasks, such as backups or reports, fail to run on time. Users can generate a unique ping URL for each background job, and the platform sends notifications when jobs do not ping within the configured timeframe. It supports 20 free cron job monitors and features an easy-to-use dashboard where users can name, tag, and organize their tasks. With configurable period and grace time settings, users can track tasks across various states, such as "up," "late," or "down," based on the timing of pings. Healthchecks.io also supports cron expressions, logs event history, and offers status badges for public display. Notifications are available through multiple integrations, including email, webhooks, Slack, and Discord, as well as incident management tools like PagerDuty and Opsgenie. The service is ideal for monitoring cron jobs, server processes, database backups, SSL renewals, and more.

upsonar.io
Most uptime monitors only check if your server responds. upsonar goes further — it loads your page and discovers every external dependency: CDN-hosted files, third-party scripts, web fonts, and API endpoints. If any of them fail, you get alerted before your users notice.
Availability checks run from multiple global regions simultaneously, so regional CDN failures and localized outages don't go undetected. Beyond uptime, upsonar monitors SSL certificates approaching expiration, tracks domain expiry dates to prevent renewal failures, and detects DNS record changes that could indicate unauthorized modifications.
All five monitoring types work together in one dashboard. Notifications reach you through email, Telegram, or webhooks compatible with Slack, Discord, and PagerDuty. Get started free with 3 websites — all features included, no credit card needed.
