MySQL vs PostgreSQL
A side by side look at reach, regional footprint and where each open source technology actually wins, built from live detections across millions of websites.
The short version. MySQL has roughly 222x more sites overall (484.1K vs 2.2K). But the split flips by market: MySQL over-indexes in Hungary, Greece and Japan, while PostgreSQL runs the majority in Belgium, Mexico and Colombia. Which one fits depends far more on your market than on raw totals.
