We swapped our home-grown components for Astralis in an afternoon. The theme seed meant every screen repainted to our brand without a single override.

The accessible defaults are the real story. Focus rings, contrast, keyboard handling — all correct out of the box, so our audit came back clean.

Semantic tokens instead of hex values changed how our designers and engineers talk. We ship the same vocabulary now.

Zero runtime CSS was the reason we tried it and the docs are the reason we stayed. Every prop I reached for already existed.

One palette change and the whole dashboard went dark-mode ready. No hunting through stylesheets, no regressions.

It reads like a design system that was actually used to build something, not a gallery of knobs. That's rare.
