upsonar.io
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.Starting Price: €10/month -

Overmonitor
Overmonitor
Infrastructure and endpoint monitoring made easy! After Monitis ceased its services last year (sold to TeamViewer) we were left scrambling for a replacement solution. We evaluated Uptrends, Datadog, dotcom-monitor, CloudRadar, Pingdom, and Uptime and came up with our own solution based on the following requirements: Cloud-based SaaS solution, small and lightweight agent, fast configuration interface, a la carte pricing model, maintenance windows that work, geotargetting at the city level, all graphs embeddable, push notifications for any alert, process monitors with rollup, and audible dashboard alerts. At the heart of our solution is a small (2.1 MB) and lightweight server agent. Once installed and "paired" it will start reporting a "heartbeat" once per minute to our "ingest" API from inside your network. Monitor, analyze, and improve website performance and end-user experience.Starting Price: $2.50 per month -
