Features

• Real-Time Collaborative Editing - Synchronizing multi-user sessions across distributed environments with end-to-end encryption to enable seamless, simultaneous visual brainstorming and content creation.
• Vector Graphics Editors - A specialized drawing environment for creating and manipulating infinite-canvas diagrams with support for custom shapes, typography, and structured data export.
• Canvas Rendering Engines - Renders vector-based shapes onto an HTML5 canvas element using a custom coordinate system to simulate a hand-drawn aesthetic.
• Embeddable Whiteboards - Embed a shared digital canvas into web applications to facilitate real-time drawing, diagramming, and visual collaboration for end users across distributed teams.
• Infinite Canvas Editors - Manipulate complex shapes, upload images, localize content, and export visual data into standard formats like PNG, SVG, or JSON for external use.
• Collaborative Drawing Engines - A real-time synchronization layer for multi-user visual collaboration featuring end-to-end encryption and local-first data persistence for distributed sessions.
• Encrypted Collaboration Engines - A synchronization layer for multi-user visual collaboration featuring end-to-end encryption and local-first data persistence for distributed sessions.
• Encrypted Collaborative Synchronization - Coordinate multi-user interactions using end-to-end encryption and offline-first data persistence to ensure automatic local saving and prevent information loss during network interruptions.
• Virtual Whiteboard Components - A reusable canvas-based interface for embedding interactive, hand-drawn style diagramming and sketching capabilities directly into web applications.
• Collaborative Whiteboards - Embed interactive sketching, diagramming, and whiteboard tools directly into web interfaces to facilitate real-time visual collaboration and brainstorming sessions for end users.
• Interactive Whiteboards - Display a persistent drawing area within a defined container to facilitate sketching, visual brainstorming, and collaborative design sessions for multiple users.
• End-to-End Encryption - Transmits serialized whiteboard updates over WebSockets using client-side cryptographic keys to ensure privacy during multi-user collaborative sessions.
• Embeddable Components - Exposes the core drawing engine as a modular library that allows external applications to mount interactive canvases within their own DOM.
• Real-Time Synchronization Engines - Synchronize real-time multi-user edits across distributed environments to maintain a consistent state for all contributors working on the same shared codebase.
• Local-First Persistence - Maintains application state in browser-local storage to ensure data availability during offline sessions and rapid recovery after interruptions.
• Self-Hosted Collaboration Platforms - A containerized application architecture for managing private instances of shared visual workspaces within custom infrastructure and controlled environments.
• Embedded Drawing Engines - Integrating a canvas-based drawing engine into existing web applications to provide users with persistent, hand-drawn style diagramming and sketching capabilities.
• Self-Hosted Applications - Managing private instances of collaborative software within custom infrastructure using containerized environments to maintain full control over data and access.
• Self-Hosted Deployment Infrastructure - Host containerized application instances under custom domains to ensure controlled access and private distribution of software within your own managed infrastructure.
• Local-First Storage - Ensuring application state remains available and consistent by leveraging browser-based storage for offline work and automatic recovery of user data.
• Event-Driven Interaction Handlers - Processes pointer and keyboard inputs through a centralized event bus to translate raw user gestures into persistent geometric shape objects.
