Seeks

Seeks is a free and open-source project licensed under the Affero General Public License version 3 (AGPLv3). It exists to create an alternative to the current market-leading search engines, driven by user concerns rather than corporate interests. The original manifesto was created by Emmanuel Benazera and Sylvio Drouin and published in October 2006. The project was under active development until April 2014, with both stable releases of the engine and revisions of the source code available for public use. In September 2011, Seeks won an innovation award at the Open World Forum Innovation Awards. The Seeks source code has not been updated since April 28, 2014 and no Seeks nodes have been usable since February 6, 2016.
User control.
Seeks aims to give the control of the ranking of results to the users, as search algorithms are often less accurate than humans. It relies on a distributed collaborative filter to let users personalize and share their preferred results on a search. Also, because of the openness of the source code, users can verify and modify the collaborative filter to fit its needs.
Forms.
Currently Seeks can be used in three main forms:
