EsyN

esyN (Easy Networks) is a bioinformatics web-tool for visualizing, building and analysing  molecular interaction networks. esyN is based on cytoscape.js and its aim is to make it easy for everybody to perform network analysis. esyN is connected with a number of databases - specifically: pombase, flybase, and most InterMine data warehouses, DrugBank, and BioGRID from which its possible to download the protein protein or genetic interactions for any protein or gene in a number of different organisms.

Networks published in esyN can be easily published in other websites using the  methodology.
