MVC framework for building realtime, collaborative applications that run in both Node.js and browsers.
Derby is an MVC framework that makes it easy to write realtime, collaborative applications running in both Node.js and browsers. It includes the Racer data synchronization engine to automatically sync data among clients, servers, and databases. The framework enables applications to load immediately, work offline, and be indexed by search engines through universal rendering.
Developers building multi-user, realtime web applications such as collaborative editors, dashboards, or interactive tools that require instant data updates and offline capabilities.
Derby simplifies realtime collaboration by handling data synchronization, conflict resolution, and offline support out of the box, while providing reactive templates and universal rendering for fast, SEO-friendly applications.

Racer engine automatically syncs data among browsers, servers, and databases with granular subscription control, eliminating boilerplate code for realtime updates.
Templates render identically on server and client, enabling immediate loading and full search engine indexing without additional configuration.
Includes capabilities for offline usage and conflict resolution out of the box, simplifying development of reliable multi-user applications.
Bindings instantly update views when models change and vice versa, making the UI highly interactive without manual DOM manipulation.
Compared to mainstream frameworks like React, Derby has a smaller community and fewer plugins, which can slow development for custom features.
The combination of MVC patterns, Racer synchronization, and reactive templates requires understanding multiple concepts, making onboarding challenging.
Documentation, while available, may not be as comprehensive or up-to-date as more popular tools, often relying on community examples and issues.
