Birdfont vs FontStruct

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.

FontStruct is an online tool for building fonts from geometric shapes arranged on a grid. Its web-based FontStructor editor lets users assemble designs called FontStructions, with controls for bricks, rotation, flipping, filters, spacing, kerning, keyboard shortcuts, and interface customization. Advanced editing includes Expert Mode, brick stacking, composite bricks, and commands. Finished designs can be downloaded as TrueType fonts for use in Mac or Windows applications; color fonts and webfont export are supported. Users can keep creations private or share them in a gallery, download other users’ fonts, and copy designs to make variations. A widget can display FontStructions on a website or blog. The site presents the service as a type-design community and as a grid-based way to teach type-design basics. It is a free service funded by advertising and sponsors. The FAQ says existing fonts cannot be uploaded, and OpenType layout tools are not included. A quick start guide and FAQ are offered, but the maker does not provide general instructions for installing fonts on specific systems.
