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.

There are many website monitoring services that can help you with this, but it’s also important to do your own due diligence. Regularly check your website yourself to ensure it’s accessible and functioning properly. Our solution can monitor websites for keywords, which are error messages or the other way round – what you expect to publish on those pages. It’s not enough to just make sure your website is up and running – you also need to monitor it for performance issues. Use a website monitoring service to track things like page load times, uptime, and error rates. This will help you identify any potential problems so you can fix them quickly, before customers notice and switch to your competition.Starting Price: $49 per month -
