New in version 2025.3

Here's an overview of the key features in NeoLoad 2025.3.

Core Web Vitals

Added support for Core Web Vitals metrics, so you can measure and optimize performance from the user's perspective. NeoLoad now captures three essential client-side metrics that can help you identify performance issues: Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS).

You can configure Core Web Vitals through the post-recording wizard, or by manually adding actions during user path design. Then, you can analyze results with views that include summary highlights, detailed statistics, and visual graphs.

RealBrowser Chromium headless enhancement

We've added more Chromium headless mode options to RealBrowser testing. You can now choose between Legacy Headless mode for better CPU efficiency and scaling, or New Headless mode for behavior that's closer to headed Chromium. This gives you more flexibility to optimize testing for your specific needs.
