Birdfont vs Bitmap Font Editor

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.

Bitmap Font Editor is a free desktop tool for creating monochrome bitmap fonts, particularly for retro computers and embedded targets such as the SAM Coupe. It supports fixed-width and variable-width fonts, with adjustable advance width for each glyph. Users draw glyphs in cells up to 32×32 pixels by clicking or dragging to paint and erase; draggable font guides and pinned reference glyphs are also available. Editing tools include undo, redo, copy, paste, clear, invert, flip, and shift. An editable sample text preview offers three zoom levels and white-on-black or black-on-white display. Raw font bitmaps can be imported with settings for starting codepoint, geometry, and byte layout. Projects use the losslessly round-trippable .fnt.json format. Export produces a 1bpp bitmap plus JSON sidecar files for widths and character mapping. Release 0.1.3 offers Windows, macOS, and Linux builds, with SHA-256 checksums. The source is MIT-licensed. Windows and macOS builds are unsigned, and system-font filling is disabled because Canvas 2D lacks TrueType hinting access.
