Bitmap Font Editor vs Calligraphr

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.

Calligraphr turns handwriting or calligraphy into downloadable fonts. Users customize a character template, print and fill it, then scan or photograph the sheet and upload it. An image editor supports touch-ups, while controls adjust character height and spacing. Multiple character variants can be randomized to create more natural-looking handwriting. Fonts download as standard TTF or OTF files and continue working independently after download. The Free plan requires registration and allows unlimited fonts, one concurrent font, 75 characters per font, and two variants per character, with no ligatures. Pro costs £6 a month, billed per month for a 6 months upgrade; it allows 20 concurrent fonts, 600 characters per font, 15 variants per character, ligatures, browser and server storage, backup, and prioritized processing. Free data is stored in the browser and may be deleted after inactivity. Users may use creations commercially without crediting Calligraphr.
