You might find similar functionality using a group of IndieWeb related plugins https://wordpress.org/plugins/indieweb/ much of which is in active development on GitHub as well. Documentation and additional information can be found at http://indiewebcamp.com/wordpress.

Some of the rest of the autoposting portions can be had through JetPack's Sharing functionality or alternately through NextScript's SNAP plugin: https://wordpress.org/plugins/social-networks-auto-poster-facebook-twitter-g/
