AppMap helps you understand new to you code, debug issues such as slow performance or security flaws.
AppMap records code execution traces, collecting information about how your code works and what it does at runtime. AppMap shows this information as interactive diagrams that you can search and navigate.
You can see how functions, web APIs, databases, security, I/O, and other services all work together when your application runs. AppMap is an extension to your code editor, so its information is always available when and where you code. Whether you are documenting your internal APIs or reverse engineering an old application, AppMap has the information you need to keep moving forward.
AppMap Diagrams: Recordings of
Runtime Behavior
AppMap Diagrams are files containing data representing the runtime behavior of an application. AppMap files can be displayed as visual maps and sequence diagrams, showing everything that the application did at runtime while AppMap was recording.
AppMap records all the HTTP requests, function calls, SQL database queries, and other important events that occurred while the application runs.
Best of all- these files stay with you, in your own code editor environment so you don’t need to worry about third-party security issues.
Visualize and Understand Application Behavior
AppMap Diagrams can be analyzed and searched to follow execution traces, locate dependencies, debug behavior, and much more. Developers being onboarded to a new code base can use AppMap Data to navigate the application in a visual way.
AppMap drastically reduced the amount of developer toil required to learn a new code base and become productive.
Automatically Scan for Runtime Problems
Once AppMap Data is generated, AppMap Analysis will immediately scan those recordings for flaws. AppMap Analysis can find security gaps, performance issues, problematic database queries, reliability issues, and more.
Unlike traditional tools, scans are almost instantaneous. Better yet, where other technologies would only identify that a security issue exists somewhere, AppMap Analysis will also show you exactly where your flaws are located, right in your code editor.
Use Cases
Code Investigation & Debugging
Learn how AppMap can help new team members get onboarded with unfamiliar code, and to debug issues faster than before.
Performance Optimization
See how AppMap Analysis can find performance problems before they become serious production problems.
Security
Scanning
Read about AppMap's ability to instantly find security issues in code that no other tool can detect.
Supported Languages & Frameworks
AppMap currently supports applications written in Java, JavaScript, TypeScript, Python, and Ruby.
Supported application frameworks include Spring, Jest, Mocha, Next.js, Express.js, Django, and Rails.
Supported Code Editors
AppMap plugins are available for VS Code and JetBrains editors (IntelliJ, PyCharm, WebStorm, and more).
The AppMap code editors provide a highly integrated experience for AppMap Diagrams, but maps can also be recorded without the AppMap native editor extensions.
Demos
Visualize Java Spring application behavior in VS Code
Use AppMap to visualize the runtime behavior of a Java Spring application as a sequence diagram.
Using AppMap Diagrams to learn how unfamiliar code works
In this example we use AppMap to explore how the eCommerce application Solidus works. Solidus is built using Ruby on Rails.
