Juxta Commons

Juxta Commons is the truncated, online version of Juxta that exists purely online. Juxta is an "open-source tool for comparing and collating multiple witnesses to a single textual work". "Powered by the Juxta Web Service, Juxta Commons offers users the option of uploading files, linking to them on the web, or creating them in its very own text editor. The visualizations that were made popular by the desktop client have been translated for use in a browser, and optimized for sharing": the heat map, the side-by-side, and the histogram.
