<p>SwiftRiver is a free, open source platform for filtering and processing large amounts of information. In particular, it can gather and filter data from common web sources such as email, Twitter or RSS. It also enables users to define 'buckets' according to their own criteria rather than relying on, for example, the information's social media popularity status. Utilizing a combination of filters and buckets, users create 'rivers' of data populated by their chosen sources. Developer Ushahidi has made all code available for general access via Github, though a custom, full-service, hosted version is available for a fee by contacting the company directly.</p>
