Ensure the monitoring tool offers a wide range of geographic testing locations that match your target audience to accurately gauge performance across different regions.

Support for Multiple Browsers

Select a tool that supports multiple browsers to ensure your website performs optimally across all platforms your users might utilize.

Alerting Capabilities

Robust alerting systems are crucial for timely issue detection. Look for tools that offer multiple alerting methods such as email, SMS, and integrations with communication platforms like Slack.
