While many uptime monitors simply verify server responses, upsonar takes it a step further by fully loading your webpage to identify all external components, including CDN-hosted assets, third-party scripts, web fonts, and API endpoints. Should any of these elements fail, you receive timely alerts, ensuring you can address issues before your users experience them. Additionally, availability checks are performed from numerous locations worldwide simultaneously, which helps ensure that any regional CDN failures or localized outages do not go unnoticed. In addition to monitoring uptime, upsonar keeps an eye on SSL certificates nearing expiration, tracks the expiration dates of domains to avoid renewal issues, and identifies changes in DNS records that could signal unauthorized alterations. The five types of monitoring operate cohesively within a single dashboard, offering you a streamlined overview. Notifications can be sent via email, Telegram, or through webhooks that integrate seamlessly with platforms like Slack, Discord, and PagerDuty. You can begin with a free plan that allows monitoring of three websites, complete with all features and no credit card required, making it easy to experience the full benefits without commitment.
