The clock's typeface comes from Custom Font, which defaults to ZCOOL XiaoWei. You can type a font name straight into the field, or click Select Font to open the font picker
The name is written verbatim into the CSS font-family, backed by system-ui. Typing a name that does not exist is therefore harmless — it simply falls back to the system default
Font Picker
The picker groups fonts into three sections, and the search box at the top filters by name:
-
LAPLACE Clock Picks — a curated set that reads well on a clock.
Arial,Georgia,Helvetica Neue, andMicrosoft YaHeiare tagged System; the rest come from Google FontsZCOOL XiaoWei,Playfair Display,Orbitron,Paytone One,Press Start 2P,Monoton,Bangers,Libre Barcode 39 Extended,Lacquer,Arial,Georgia,Helvetica Neue,Microsoft YaHei,Noto Sans SC,Noto Sans TC,Share Tech,Share Tech Mono -
All Fonts — the full Google Fonts catalog. Each entry shows how many variants it has and previews in the font itself
-
Local Fonts — only appears after you click Load Local Fonts and grant the browser permission, covered below
Google Fonts
The full catalog is fetched through this site's proxy endpoint and cached indefinitely. If that endpoint is unreachable, the picker falls back to a built-in list of popular fonts and keeps working
Fonts load on demand: only the one currently in use requests a stylesheet from fonts.googleapis.com, rather than the whole catalog being downloaded
The browser source in OBS also needs network access to load Google Fonts. If
the streaming machine cannot reach fonts.googleapis.com, use a locally
installed font instead
Local Fonts
Load Local Fonts reads the machine's installed fonts through the browser's Local Font Access API so you can browse and preview them directly. The API is currently limited to some Chromium-based desktop browsers, and the browser prompts for permission before any font is read
You do not have to click the button at all — a local font name typed into the field on the left works just as well. This site never uploads or collects information about your local fonts
A local font only renders if it is installed on the machine running OBS. If you configured the clock on a different computer, make sure the same font exists on the target machine
Font Compatibility for Older Links
Early versions named the built-in fonts with var(--clock-font-*) CSS variables. Those values are still recognized and get mapped to the real font name at render time, so addresses shared years ago and already saved in OBS keep working untouched
