Fontello vs Shift

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.

Shift is a free, open-source desktop font editor for designing variable fonts on macOS, Windows, and Linux. Version 0.1.1 is the first alpha release, and the maker says workflows and document details may change. The editor draws and edits straight and cubic curves, shapes, points, handles, side bearings, and advance width. Shape operations include moving, resizing, rotating, flipping, aligning, distributing, union, intersect, and subtract on closed contours. Users can inspect and edit variable-font axes, sources, mappings, style labels, and named instances. The glyph catalog uses Hyperglot language data to indicate required characters for selected languages and scripts. Shift opens `.shift` documents and inspects TTF, OTF, UFO, Designspace, Glyphs, and Glyphspackage sources. TTF and OTF files are view-only previews. Editable `.shift` files can be saved and TrueType fonts exported. Text proofing and complete spacing and kerning workflows are not yet available.
