Prototypo vs Type Light

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.

Type Light is a free TrueType font editor for Windows, macOS, and Linux. It creates and modifies TTF fonts, including custom symbol and barcode fonts. Drawing tools make glyphs from straight lines and quadratic Bézier curves, with operations for combining or subtracting shapes. You can assign Unicode values or custom encodings to glyph slots and set horizontal metrics. Basic kerning tables and pair adjustments are supported. Metadata controls cover family name, style flags, copyright strings, and embedding permissions. The editor exports Windows-compatible TTF files that the product page says work in Office applications, Adobe products, and web browsers. No registration is required, and the free plan has no feature restrictions or trial period. Created fonts may be used commercially. Type Light does not provide OpenType features, variable fonts, or PostScript Type 1 support, and its undo history is limited.
