Fontra vs FontStruct

Fontra is a free, open-source browser-based font editor designed around variable fonts. It was initially developed to make designing and producing large CJK fonts more efficient. Its architecture combines a JavaScript browser client and Python server, which can run locally or remotely. Fontra Pak bundles the application for desktop use and local file editing; a remote server setup allows real-time collaboration among users, with changes propagating across windows. The project supports reading and writing Designspace and UFO files, as well as reading and exporting TTF and OTF files, including variable fonts. Editing features include live text entry, designspace axis navigation, interpolation, OpenType features, outline editing, components, anchors, guidelines, background images, transformations, kerning, font metadata and variation-axis mapping. Fontra Pak has binaries for macOS 11 and newer, Windows 10 and newer, and Ubuntu x86_64. Linux users can also use Flatpak or Snap; source compilation is listed for other architectures such as ARM or PPC. The repository is licensed under GPL-3.0.

FontStruct is an online tool for building fonts from geometric shapes arranged on a grid. Its web-based FontStructor editor lets users assemble designs called FontStructions, with controls for bricks, rotation, flipping, filters, spacing, kerning, keyboard shortcuts, and interface customization. Advanced editing includes Expert Mode, brick stacking, composite bricks, and commands. Finished designs can be downloaded as TrueType fonts for use in Mac or Windows applications; color fonts and webfont export are supported. Users can keep creations private or share them in a gallery, download other users’ fonts, and copy designs to make variations. A widget can display FontStructions on a website or blog. The site presents the service as a type-design community and as a grid-based way to teach type-design basics. It is a free service funded by advertising and sponsors. The FAQ says existing fonts cannot be uploaded, and OpenType layout tools are not included. A quick start guide and FAQ are offered, but the maker does not provide general instructions for installing fonts on specific systems.
