Fontello vs Prototypo

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.

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.
