Birdfont vs Fontello

Birdfont is a font editor for creating vector graphics and exporting TTF, OTF and SVG fonts. It runs on Linux, Windows and macOS, and supports monochrome and color font formats. SVG files from Inkscape and Adobe Illustrator can be imported. The Open Source plan costs nothing and includes TTF and monochrome SVG fonts, kerning, ligature substitutions, alternates, SVG import and commercial use. The Freeware plan also costs nothing, and allows creation of free fonts under the SIL Open Font license. Commercial costs $4.99, paid once; it includes commercial fonts and one year of upgrades, while the purchased version continues to work afterward. Plus costs $9.99, paid once and adds color fonts, OpenType SVG, OTF, COLR/CPAL, single-stroke CNC fonts and variable fonts. Plus can export multiple static fonts from a variable master. Birdfont is also available through Steam. The app does not collect user data by default; crash reports are optional.

Fontello is a free web and API service for turning vector artwork into icon webfonts for websites. It can reduce glyph collections and combine symbols from multiple fonts into one generated file. The web app includes open-source artwork and accepts custom SVG icons or SVG fonts by drag and drop. Generated files arrive in a single ZIP archive, with a config.json file that can be imported later to continue editing. Its API can create a session from a font configuration, reopen that project, and download the resulting font; API sessions remain stored for 24 hours. Fontello lists Makefile, Node.js, Ruby, and Grunt integrations for workflow automation. It does not offer accounts for project storage, so archives should be kept in version control. Generated font icons are single-color. The code is MIT-licensed, while embedded fonts retain their own licenses.
