Open-source Automated Programming Assistant

Website :: Knowledge Base :: Roadmap


Source++ is an open-source automated programming assistant with runtime-aware and context-aware functionality. Source++ is an observant-only programming assistant and aims to bridge application performance management (APM) solutions with the software developer's integrated development environment (IDE), enabling tighter feedback loops. Source++ can be used to help debug and prevent runtime issues by providing contextualized behavior about your source code throughout development.


  1. To enable developers easy access to feedback-driven development methodologies
  2. APMs often lack tight integration with actual development of the source code they monitor
  3. Source code comprehension can be improved by providing an extra dimension of behavior linked with said source code (ie. being able to visualize how a particular method acts in production vs. locally)
  4. No websites or dashboards necessary to debug complex asynchronous runtime issues
  5. AI-based pair programming is going to be pretty cool when we get it right

Gutter Marks

Mark Meaning
Method handles user requests (SOAP, REST, etc)
Method has thrown exception in application's most recent run
Indicates the span stack is a child of the trace created by method caller

Getting Started


  • Supported APMs: Apache SkyWalking
  • Supported IDEs: JetBrains
  • Supported OSes: Linux, macOS, and Windows


Downloading the IDE

Install a JetBrains IDE if you don’t already have one.

Install the Source++ Plugin

  1. Press Ctrl+Alt+S to open the Settings dialog and then go to Plugins.
  2. Click the Install JetBrains plugin.
  3. In the dialog that opens, search for SourcePlusPlus (direct link).
  4. Press Install.
  5. Click OK in the Settings dialog and restart your IDE.

After installation, you will need to configure the Source++ Plugin (see Configure Plugin).
