About
Open Comparator is a single comparison engine. Every topic is a table of entities and numeric metrics. You pick one entity and one metric, and the site shows where it stands: its rank, its percentile, and how far it sits from the average of the field.
One engine, many topics
Football players, countries, billionaires, clubs, NBA players, companies, YouTube channels, cities, movies, and smartphones all run on the same code. A topic is just a data file, so new topics can be added without rebuilding the site.
Free and private
There is no login and no account. Everything runs in your browser. The numbers are approximate public-reference snapshots meant for quick comparison and entertainment, not official statistics.
