Birdfont vs PixelForge

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.

PixelForge is a pixel font editor for creating and editing bitmap fonts, then exporting them from the app. Its glyph tools draw and erase pixels and can move, rotate, flip, or scale glyphs. A text preview updates as glyphs change, and multiple font projects can remain open with separate undo histories. The editor can work with glyphs through U+FFFF, including unassigned ranges. It imports pixel fonts into its editable format and exports TTF files with metadata support. PixelForge periodically saves open documents and offers recovery after a crash. Project files use plain text, which the maker describes as compatible with version control and diffs. The current 0.91b pre-release runs on Windows and Linux and is free to download until version 1.0; the maker says no licensing or payment system is set up yet. The app supports monochrome 1-bit bitmap fonts, with one size and one weight per font. Sergi Lázaro is credited as its maker.
