The Excalidraw extension for VS Code (a free code editor) lets developers draw system diagrams (visual maps of how code or data moves) right inside their coding environment. You never have to switch apps to explain a technical process to a teammate. Small dev teams spend less time on back-and-forth explanations.
Open VS Code and go to the Extensions panel
Search for 'Excalidraw' and install the official extension
Create a new file with the .excalidraw extension in your project folder
Draw your system or code flow diagram directly in VS Code
Commit the .excalidraw file to your project repo (a shared code storage system) so the whole team can view and edit it
