Birdfont vs Prototypo

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.

Prototypo is an online app for designing typefaces from four parametric starting points: Prototypo Fell, Prototypo Grotesk, Prototypo Elzevir, and Spectral. Its controls cover more than thirty characteristics, including thickness, aperture, and roundness, with separate adjustments for serif details. Users can change individual letters or groups of letters, then export fonts in OTF format for installation on macOS, Windows, or Linux, or display them in a browser. A Chrome extension previews font changes on websites, and fonts can be sent to Glyphr Studio for further editing. Prototypo supports the Latin Extended 3 glyph set, but has no cursive templates and does not let users import their own fonts to modify. The maker says exported fonts use a CC0 license, permitting commercial use without permission. The free plan has limited parameter range and one week of support; Pro is $8.25 per month and Team is $49.96 per month. The FAQ lists a free trial and requires an up-to-date Chrome, Firefox, or Opera browser.
