Oh Dear is a subscription-based website change monitoring tool designed for organizations seeking an all-in-one solution to track uptime and SSL health for their websites and applications. The platform offers a user-friendly interface with advanced features such as API access, webhook support, and integration with popular communication tools like Slack and Discord. Additionally, alerts can be sent through various channels including email and Pushover, ensuring that users receive timely notifications about their website's status.

The service employs a dual-location check system to enhance reliability. If the primary monitoring location detects an issue, a secondary location verifies the problem before triggering an alert. This minimizes false positives and ensures that users are only notified of genuine downtime. Oh Dear is suitable for a wide range of organizations, including small businesses, nonprofits, and enterprises, making it a versatile choice for anyone needing robust website monitoring.
