AppMap for Visual Studio Code

AppMap is a free and open source visualization tool that allows you to see how your software works as it’s running. You can use AppMaps to onboard to unfamiliar code, debug hard-to-fix issues, review code behavior changes before making a commit, and improve the quality of code reviews.

AppMap works best for mapping web services and web applications. Join our community to help us expand support for more types of applications and frameworks!

Requirements

Currently, AppMap supports Spring, Django, Flask, Rails and Express projects (AppMap for JavaScript is now available in beta!). The most up-to-date list of frameworks and languages we support is here.

To start making AppMaps, you’ll need to install and configure the AppMap client agent for your project. Then, you’ll make AppMaps by running your app - either by running test cases, or by recording a short interaction with your app.

Here's a convenient quickstart guide that walks you through the AppMap install flow.

Summary of features

Summary of Features:

• Interactive maps of code’s behavior, so you can see what code is really doing as it runs, including:
  • Dependency maps that display how your app’s components are all connected, so you can quickly see how changes affect the big picture
  • Trace diagrams that show details about how a feature works, so you can find optimization opportunities and investigate tricky bugs
  • SQL query data, so you can see exactly what’s happening between your code and the database
  • Web services data, so you can see what message your app received and how it responded
  • Labels that identify the key functions in source code, so you can easily find critical code events and ensure they’re configured and used properly
