Cufón is similar to Typeface.js which aims to become a worthy alternative to sIFR, and despite its merits still remains painfully tricky to set up and use. Cufón consists of two individual parts as well – a font generator, which converts fonts to a proprietary format and a rendering engine written in JavaScript.

It works on every major browser on the market. There is near-zero configuration needed for standard use cases. And it is fast, even for sufficiently large amounts of text.
