Pre-FIX your code

Improving the performance of your applications before you even submit the pull request is easy with Prefix.

1. Install Prefix

Prefix runs on Windows and macOS to measure the realtime app performance on your development workstation. It's like wielding the power of Retrace on your laptop. If you haven't already, GO DOWNLOAD PREFIX.

Prefix v4 is a native application:

Once installation is complete, you can run Prefix like any other app... via the Windows Start menu or macOS Launchpad.

2. Configure your Language

Let Prefix know what programming language your using. Configuration is easy and we currently support 6 popular languages. Click on the language / system link for instructions on setting up the profiler on your workstation.

3. Restart Applications and Server

Prefix communicates with the profilers via environment variables to enable Prefix specific functionality. In the case of the .NET profiler these environment variables enable the profiler to trace an application. After the initial install of Prefix, you will need to restart any command prompts, IDEs or Web Servers that you will be using to launch applications that you want to capture in Prefix. This includes things like Visual Studio, Eclipse, Netbean, IIS, Tomcat, Glassfish, JBoss, etc.

4. Use Your App

As you view the app in your browser Prefix listens in the background and streams the requests, traces and logs to the Prefix UI in realtime.

Simply click on a request that you'd like to dive into and the full trace appears complete with inline DB queries, web requests, logs and errors.
