Apache CouchDB

Apache CouchDB is more than just a document store; it's a database with powerful, built-in synchronization capabilities. This core feature allows data to be reliably replicated across a cluster of database nodes or to remote client devices, such as phones and laptops. This innate sync mechanism is perfect for building collaborative web apps and responsive mobile applications that work with or without an internet connection. By handling the complexities of data conflict resolution and distribution, CouchDB allows developers to focus on creating great user experiences, backed by a dependable and distributed data layer.
