Spacedeck Open
Spacedeck is a web-based collaborative whiteboard platform that provides an infinite canvas for real-time visual brainstorming and project management. It enables multiple participants to interact simultaneously within a shared workspace, synchronizing drawing, writing, and media placement across browser-based interfaces.
The platform distinguishes itself through a container-native deployment model and a plugin-based storage abstraction, allowing users to manage their own infrastructure while connecting to local file systems, cloud object storage, or relational databases. It maintains document consistency during concurrent edits through operational transformation rules and ensures real-time state synchronization across clients using persistent bidirectional socket connections.
The application supports a broad range of content management capabilities, including the embedding of multimedia assets and the transformation of whiteboard layouts into structured, zooming presentations. Users can also localize the interface through external language packs and export project data into standard document or archive formats for offline distribution.
The software is designed for self-hosted environments, utilizing containerization to ensure consistent execution and simplified scaling across diverse hosting platforms.
Features
- Collaborative Whiteboards - Provides an infinite canvas for drawing, writing, and arranging multimedia content to facilitate real-time visual collaboration.
- Canvas-Based Rendering - Renders complex visual scenes by mapping multimedia objects and drawing primitives onto a high-performance HTML5 canvas element.
- Real-time Collaborative Editors - Facilitates working together on an infinite digital canvas to brainstorm, sketch, and organize visual ideas in real time.
- Operational Transformation Sync - Maintains consistency in shared documents by merging concurrent user edits into a single linear history using mathematical transformation rules.
- WebSocket State Synchronization - Synchronizes canvas state across multiple clients by broadcasting incremental operational changes through a persistent bidirectional socket connection.
- Collaborative Project Planning - Enables embedding images, videos, and audio files into a shared workspace to create rich visual documentation and interactive project roadmaps.
- Self-Hosted Project Management - Provides a containerized application for managing collaborative whiteboards with configurable storage backends and support for exporting project data.
- Configurable Storage Backends - Supports connections to local file systems, cloud object storage, or relational databases to ensure persistent data and media accessibility.
- Application Server Container Deployments - Packages the application and its runtime dependencies into isolated images to ensure consistent execution across diverse cloud and server environments.
- Containerized Deployments - Supports packaging into isolated containers to simplify installation, scaling, and infrastructure management.
- Self-Hosted Deployments - Supports managing and scaling a collaborative web service within isolated containers to maintain full control over data storage and infrastructure.
- Storage Abstractions - Decouples data persistence from the core application logic by using interchangeable drivers for local files, cloud buckets, or relational databases.
- Drag-and-Drop Asset Insertion - Allows users to drag and drop images, videos, and audio files onto the canvas to enhance visual communication.
- Presentation Modes - Transforms whiteboard elements into a structured, zooming presentation to effectively share complex ideas and project workflows.
