Mapping parametric font tooling

Carl Enlund

Hi! I've spent the last few months deep in parametric type and wanted to map what tech is out there. I made a similar thread before about web tools and thought parametric type deserved one too.

By "parametric type" I mean fonts where changing a variable changes glyph shapes across the whole font.

Variable fonts are of course the standard way to distribute this kind of font, but on the editing side there's a much wider range of tools.

There are full parametric editors like Prototypo, Metafont/Metaflop, Metapolator, Burrowlab, and the more recent Symphonty https://typoland.com

Then there are things like LTTR/INK's engine, and specialized experiments like Spine Sans https://noacubestudio.github.io/spine-sans and Brutalita Sans https://brutalita.com

And local parametric systems inside normal editors, like smart components in Glyphs, and variable components in Fontra.

I also recently saw this, where an existing font (Inter) is retroactively mapped to a new set of parameters:
