Cloudflare has introduced Performance Experiments in its Observatory platform to allow website owners to safely test and implement code optimizations without affecting their live sites or user experience. The new feature enables users to input desired codes, run Observatory's testing suite, and observe the impact on their Lighthouse score before deciding to implement the changes. This approach helps users identify performance improvements while minimizing the risk of outages or other issues. Observatory integrates Real-User Monitoring (RUM) data and synthetic tests for easier website performance monitoring and optimization. The platform also offers tailored Cloudflare settings based on Lighthouse test insights and RUM data, helping users boost their performance score effortlessly with a single click.
