Glue42 Core is the world's first open source web integration platform. It enables multiple standalone web applications to share data between each other, expose functionality, open and manipulate windows. Glue42 Core is mainly targeted for use with Progressive Web Applications. Combining PWAs with Glue42 Core not only leverages the advantages of PWAs (native-like feel, working offline, enhanced performance, etc.), but incorporates an interoperability layer in your web application ecosystem as well.
