# TruClient 2.0 - Web protocol

TruClient 2.0 is a tool for recording and developing web scripts. The TruClient engine records the actions you perform in your browser, and creates a script in real time, presented in a graphical, user-friendly interface.

In this topic:

## Introduction

The TruClient 2.0 - Web protocol enables you to create Vuser scripts that can be used for load testing or monitoring web-based applications. It enables you to more accurately track end-user experience and metrics.

TruClient 2.0 has its own distinctive user interface and script structure. It provides you with the following:

Feature | Description
--- | ---
Intuitive UI | A Development window with a specialized, intuitive interface, using dark theme for comfortable viewing.
Web browser recording | Recording and replay supported on your locally-installed browser, up to the latest versions.
Real-time conversion | When recording, you see the actions you perform trigger corresponding script steps in real time.
Visual replay | During replay, you see your business-process steps as they are performed.
Comprehensible steps | Script steps presented graphically, in plain English (rather than lines of code, as in other protocols).
Simple script creation | Ability to quickly and efficiently create scripts that emulate user actions, without extensive coding knowledge.
Streamlined editing | Dynamic editing functionality that enables you to modify the elements of a step, drag and drop steps to reorder them, and synchronize steps.
Debugging options | Advanced object identification technology, including snapshots of the interactive steps, and suggestions for alternative automation steps.
Script enhancement | Support for standard VuGen functionality such as parameterization and transactions.
Advanced customization | Options for integrating JavaScript and C code, and API utilities.

## Comparison with the TruClient - Web protocol

The TruClient 2.0 - Web protocol is the evolution of TruClient 1.0 for browser-driven testing, reducing the need for complex scripting.

It provides the following enhancements when compared with the original TruClient - Web protocol:

- Next generation TruClient engine.

- Improved Development window user interface, with more streamlined editing functionality.

- Locally installed Google Chrome, Microsoft Edge, and Mozilla Firefox browsers supported for recording and replay.

- Decoupled from embedded browser, so no need to wait for release updates for new browser versions.

- Fully cross-platform with Linux support, which helps you to reduce your footprint and your total cost of ownership, by reducing managed infrastructure.

- Test runs supported on Linux Ubuntu load generators, in addition to Windows.

- Updated, dedicated set of asynchronous API (JavaScript) functions.
