plex

IBM Plex is IBM's open-source corporate typeface family, released under the Open Font License (OFL). The project provides the typeface source files and multiple output formats intended to support a wide range of typographic situations, including user interface environments. The family includes four main designs: IBM Plex Sans, IBM Plex Serif, IBM Plex Mono and IBM Plex Sans Condensed. Each comes with Roman and true italic styles. IBM Plex Sans is documented as supporting extended Latin, Arabic, Chinese (Traditional), Cyrillic, Devanagari, Greek, Hebrew, Japanese, Korean and Thai. A separate release, IBM Plex Math, adds over 5,000 glyphs covering mathematical symbols such as alphanumeric, double-struck, Fraktur, operators, script, icons, arrows, Greek letters, phonetics, and technical and geometric shapes. It is described as compatible with IBM Plex Serif Regular. Installation is handled by downloading the latest zip files from the project's releases page. The repository also publishes a set of NPM packages for individual designs and script variants, including @ibm/plex-math, @ibm/plex-mono, @ibm/plex-sans, @ibm/plex-sans-arabic, @ibm/plex-sans-condensed, @ibm/plex-sans-devanagari, @ibm/plex-sans-hebrew, @ibm/plex-sans-jp, @ibm/plex-sans-kr, @ibm/plex-sans-tc, @ibm/plex-sans-sc, @ibm/plex-sans-thai, @ibm/plex-sans-thai-looped and @ibm/plex-serif. This makes the repository useful both for designers and developers who need to install the fonts on a device and for web or application projects that prefer to consume the fonts through package managers.
