Difference between PouchDB and Couchbase

1. PouchDB :
PouchDB is an open-source, NoSQL, in-line database. It is designed after CouchDB, which is a NoSQL database that powers npm. It is written in JavaScript language. There is no need to perform queries over the network as PouchDB resides inside the browser and thus it makes it extremely faster. It stores data locally using IndexedDB and WebSQL in the browser.

It was developed by Couchbase, Inc. and initially released in August 2010. It is written using C++, Erlang, C, Go languages and its server is designed to provide us with easy-to-scale key-value or JSON document access with high sustained throughput and low latency.
