Testimonials
GRAVITY turned our weekly type‑testing ritual into a five‑minute task. The variable‑axis sliders are buttery smooth.
The kerning overlay saved us hours on a recent branding overhaul. Exporting proofs directly to Figma is a game‑changer.
As a foundry, we use GRAVITY to generate specimen sheets for new releases. The API output is clean and ready for our site.
