We are pleased to introduce NeoLoad 2025.3, a release designed to help teams validate digital performance in ways that reflect what matters most today: real user experience and AI-driven automation.
With Core Web Vitals support in RealBrowser, high-capacity cloud load generators, and expanded Model Context Protocol (MCP) capabilities, this update strengthens NeoLoad’s position as the performance testing solution that unites scale, speed, and usability.
Core Web Vitals in RealBrowser
For the first time, NeoLoad RealBrowser captures Google’s Core Web Vitals:
- Largest Contentful Paint (LCP): Measures loading performance, showing how quickly users see meaningful content.
- Interaction to Next Paint (INP): Validates responsiveness, ensuring interactions feel immediate.
- Cumulative Layout Shift (CLS): Tracks visual stability, identifying unexpected layout changes that disrupt users.
Why this matters:
By capturing Core Web Vitals during test execution, NeoLoad helps organizations bridge the gap between backend performance and real-world user experience. This is particularly critical for public-facing applications, where poor scores not only frustrate customers but also reduce visibility in search rankings. Teams can now optimize for speed, responsiveness, and stability within the same workflows they already rely on for performance testing.
High-Capacity Cloud Load Generators
NeoLoad 2025.3 introduces larger, more powerful cloud load generators, offering 16 CPU and 64 GB RAM per generator. These high-capacity options make it easier to test complex, resource-intensive scenarios at scale.
This capability is designed for teams that need to simulate peak traffic conditions, validate media-rich user journeys, or run large-scale browser-based tests without the burden of managing infrastructure. It ensures that organizations can reflect real-world usage patterns with confidence and efficiency.
Expanded Model Context Protocol (MCP)
With this release, NeoLoad expands its support for Model Context Protocol (MCP), enabling more powerful natural language-driven workflows. Teams can now:
- Manage test environments through simple prompts, including creating, sizing, and controlling zones.
- Retrieve detailed insights such as transaction values, request data, and log information.
- Run interval-based analysis to understand performance trends over time.
- Generate stakeholder-ready reports instantly, reducing manual reporting effort.
These enhancements extend NeoLoad’s role in AI-driven quality engineering, helping teams work faster, share clearer insights, and simplify complex performance tasks.
New features in the enhanced NeoLoad Web
With NeoLoad 2025.1, we also made available our new and enhanced interface for NeoLoad Web, supported on the backend by our updated fully open V4 API architecture. Our aim was not only to deliver a user experience and aesthetic to be more consistent with other Tricentis solutions, but to maintain the capabilities users have come to expect from NeoLoad Web while delivering new innovation as well.
One new example is the availability of an analysis treeview. From the Results>Values tab, users can aggregate and sort through various metrics such as requests and transactions, as well as a shared containers view and the ability to trace timeseries instantly, allowing for the generation of graphs on the fly. For those that work in NeoLoad GUI, this has been a requested view that we carry over into NeoLoad Web.
Why NeoLoad 2025.3 Matters
Performance testing is no longer just about server throughput. Modern digital experiences demand validation of the speed, responsiveness, and stability that users actually perceive. At the same time, organizations need AI-enabled automation to match the pace and complexity of today’s software delivery.
With NeoLoad 2025.3, teams can test like their users experience it, scale their testing with confidence, and embrace AI-driven workflows that reduce friction and accelerate outcomes.
Summary of Release Highlights
- Core Web Vitals (LCP, INP, CLS) captured directly in RealBrowser tests
- High-capacity cloud load generators for large-scale, browser-heavy scenarios
- Expanded MCP for environment management, interval-based insights, and instant reporting
