FontForge

FontForge is a powerful, open-source font editor that has been a staple in the type design community for decades. It supports a wide range of font formats including TrueType, OpenType, PostScript, and SVG fonts, making it one of the most versatile free tools available for font creation and editing. The software offers advanced features like spline manipulation, kerning tables, and scripting via Python, giving experienced typographers deep control over their designs. However, it's important to note that FontForge is not truly an AI font generator " it's a traditional font editor that relies entirely on manual design work. The interface feels dated and has a steep learning curve that can intimidate beginners. There are no AI-assisted generation features for automatically creating glyphs or styles. For users seeking genuine AI-powered font generation, tools like Calligrapher.ai or Prototypo may be more fitting. That said, as a free, open-source font editor, FontForge remains an invaluable resource for designers on a budget who don't mind the manual workflow.
