Derby is a full-stack MVC framework for building realtime, collaborative web applications that run in both Node.js and the browser. It includes the Racer data synchronization engine, which syncs data among browsers, servers, and databases with conflict resolution and offline support.

Use cases

• build realtime collaborative apps like shared editors or whiteboards
• sync data automatically between browser, server, and database
• write isomorphic apps with server-rendered templates for SEO and fast loads
• create multi-user apps with conflict resolution and offline support
• build component-based UIs with live model-view data bindings

When to choose

• you need realtime multi-user collaboration with automatic data sync
• you want the same templates rendered on both server and client
• you want offline support and conflict resolution out of the box
• you prefer a Node.js full-stack MVC approach with granular model subscriptions

When to avoid

• you need a framework with a large active community and ecosystem
• you only need a simple REST API backend without realtime sync
• you require a license file in the repository (none is present in the repo)
• you want frequent releases or cutting-edge features
