The DejaVu fonts are a superfamily of fonts designed for broad coverage of the Unicode Universal Character Set. The fonts are derived from Bitstream Vera (sans-serif) and Bitstream Charter (serif), two fonts released by Bitstream under a free license that allowed derivative works based upon them; the Vera and Charter families were limited mainly to the characters in the Basic Latin and Latin-1 Supplement portions of Unicode, roughly equivalent to ISO/IEC 8859-15, and Bitstream's licensing terms allowed the fonts to be expanded upon without explicit authorization. The DejaVu fonts project was started with the aim to "provide a wider range of characters ... while maintaining the original look and feel through the process of collaborative development". The development of the fonts is done by many contributors and is organized through a wiki and a mailing list.
Thesis is a large typeface family designed by Luc(as) de Groot. The typefaces were designed between 1994 and 1999 to provide a modern humanist family.

Everson Mono is a monospaced humanist sans serif Unicode font whose development by Michael Everson began in 1995. At first, Everson Mono was a collection of 8-bit fonts containing glyphs for tables in ISO/IEC 10646; at that time, it was not easy to edit cmaps to have true Unicode indices, and there were very few applications which could do anything with a font so encoded in any case. The original "Everson Mono" had a MacRoman character set, and other character sets were provided as separate files named with suffixes: "Everson Mono Latin B", "Everson Mono Currency", "Everson Mono Armenian" and so on. A range of fonts with the character set of the ISO/IEC 8859 series were also made. A single Unicode font file incorporating most or all of the characters from all of the previous separate Everson Mono files was named "Everson Mono Unicode" in 2003, but since 2008 the single large font has been named simply "Everson Mono". At present, there are regular, italic, bold, and bold-italic styles.

The Public Type or PT Fonts are a family of free and open-source fonts released from 2009 onwards, comprising PT Sans, PT Serif and PT Mono.

It is a slightly wider and calmer adaptation of Spiekermann's typeface Meta, which was used at Mozilla's brand typeface at the time but optimized for legibility on (small) screens. With the name Fira, Mozilla wanted to communicate the concepts of fire, light and joy but in a language agnostic way to signal the project's global nature. Fira was released in 2013 initially under the Apache License and later reissued under the SIL Open Font License.
