Apache Usergrid is a Backend-as-a-Service (“BaaS”) built on Cassandra, and accessible via a REST API. Any app can store data in Usergrid. There's an SQL-like syntax for running queries, with full property indexing, full-text search, and geolocation search.

Apache Usergrid is an open-source project implementing a NoSQL Backend-as-a-Service (“BaaS” or “mBaaS”) that can be used in any app to store any structured data. The store is built on Cassandra, and it offers several ways for apps to connect: a REST API, and a number of client-side libraries for JavaScript, Objective-C, and so on.

For administering the system, there's an admin portal that enables developers to rapidly build and manage web and/or mobile applications.

Usergrid provides the most common services required for building apps, such as user registration & management, data storage, file storage, roles, and permissions, and features SQL-like syntax for running queries, with full property indexing, full-text search, and geolocation search.
