Fumadocs Theme for Starlight
A Starlight plugin that swaps out core components to get the FumaDocs look — without leaving the Astro ecosystem.
Live Demo
Section titled “Live Demo”What it does
Section titled “What it does”Overrides 10+ Starlight components — Header, Sidebar, TOC, Pagination, Footer — and replaces them with FumaDocs-style equivalents. Everything is tied to a --fuma-radius token system, so the whole thing is easy to adjust.
The TOC has a physics-based glide indicator that stretches and snaps between headings as you scroll. The sidebar uses vertical rails with active-state bars to show document depth.
Drop it into astro.config.mjs as a plugin and it handles the rest.
