Today we are announcing Fontalog - the world's biggest font database!

What is it? Fontalog is a searchable, super-fast, free database of fonts, created by FontBase. You can search fonts by visual characteristics, the same way you can do in our SuperSearch: proportion, contrast, weight and xHeight. On every font page there are multiple similar fonts displayed along with foundry info and exact parameter numbers, which you can use to search even more fonts.

How did we do this? No AI was used to create this. We analyze each font added to FontBase locally using the opentype.js library. We render the text off-canvas and measure key characteristics: stroke width; difference between bold and thin strokes; the relation of "x" letter height to capital letters; width of the letters compared to height; "i" size compared to "w" size. From these calculated numbers, we then build weight, proportion, xHeight and contrast. We also analyze the font's naming table to retrieve the basic info like font name, foundry and style names. No fonts are uploaded to our servers in the process.

Fontalog is constantly expanding as there are new fonts released and added to the database. We will monitor the website for performance and add new features moving forward. And as always we are open to feedback on how we can improve it!
