Birdfont vs Shift

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.

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.
