Parametric font editor to tweak, preview, and export custom typefaces instantly

Modulator is a web‑based font tool from Metaflop that lets designers reshape existing metafonts in real time. Choose a base font (Adjuster, Bespoke, Fetamont, Funtauna) and adjust parameters such as unit width, pen width, cap height, x‑height, contrast, slant, aperture and overshoot. Live previews show glyph anatomy, charts and a typewriter view. When finished, download the customized typeface as an OpenType file or a web‑font for immediate use.
