FontStruct vs Prototypo

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.

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.
