Compare projects
Project comparisons allow you to view any selection of projects side by side just like they're shown on regular categories or in search results. You can try out an example or start yourself by adding a library to the comparison via the input below. You can also easily share your current comparison with others by sending the URL of the current page.

The ActiveFacts API is a Ruby DSL for managing constellations of elementary facts.
Each fact is either existential (a value or an entity), characteristic (boolean) or
binary relational (A rel B). Relational facts are consistently co-referenced, so you
can traverse them efficiently in any direction. Each constellation maintains constraints
over the fact population.
