Some of the better known ones are https://github.com/huacnlee/social-share-button https://github.com/huacnlee/social-share-button and https://github.com/adamstac/zocial https://github.com/adamstac/zocial though these don't have all the buttons of shareable and vice versa. I can't speak for the others but my gem doesn't need to be required in the view level and configuration is straight forward. Try them out and choose the best fit for you!
