FontLab

FontLab is a heavyweight font editor made for serious type design. It’s not the prettiest or the newest, but it’s deep, flexible, and handles large families and variable fonts better than most. If you’re working on full systems with multiple masters, OpenType features, or complex interpolation, it gives you the control you need without getting in the way.

The drawing tools are solid and built for precision. You’ve got smart guides, brush tools, and snapping that actually feels useful instead of annoying. The spacing and kerning tools are tight, and it gives you live previews across your masters so you can fine-tune rhythm without bouncing between exports. It also plays nice with UFOs, .glyphs files, and other formats, which makes it easier to move between tools if needed.

FontLab isn’t the easiest tool to jump into. The interface can feel cluttered and the learning curve is real if you’re used to something simpler. But once you’ve dialed it in, it gives you deep control over every part of the font. The interpolation tools are rock solid, the metrics system is reliable, and you can manage complex production workflows without needing five separate apps. If you’re building full families or pushing into advanced OpenType work, FontLab holds up under pressure.
