Excalidraw
This project is a virtual whiteboard component and vector graphics editor designed for creating diagrams with a hand-drawn aesthetic. It provides a canvas-based drawing engine that can be embedded directly into web applications, allowing users to manipulate shapes, upload images, and export visual data into standard formats like PNG, SVG, or JSON.
The platform distinguishes itself through a real-time synchronization layer that supports multi-user collaboration across distributed environments. This engine utilizes end-to-end encryption to secure shared sessions and employs a local-first data persistence model, which ensures that application state is maintained in browser storage to prevent data loss during network interruptions.
Beyond its core drawing capabilities, the software supports self-hosted deployment, allowing teams to manage private instances within their own containerized infrastructure. The system handles complex user interactions through an event-driven architecture that translates pointer and keyboard gestures into persistent geometric objects, while also providing options for custom typography to maintain visual consistency across workspaces.
Features
