Scheduling infrastructure for everyone.
Open-source meetings, calendars, and booking links that just work — for individuals, teams, and the developers building the next wave of scheduling on top of an API they can read.
What this fixture exercises
A calendar that gets out of the way.
Cal Sans speaks. Inter explains.
A custom geometric display face for headings, Inter for body. The font pairing enforces a clear typographic division — Cal Sans is never used below 16px.
Read the pairing →Shadows do the bordering
A multi-layer ring + contact + ambient shadow stack replaces CSS borders. Surfaces feel like physical cards sitting on a table — never floating, never flat.

Get scheduling at the speed of Cal.
Inputs are minimal: hairline border, charcoal text, and the one link-blue makes its second appearance only on the focus ring — exactly where it earns its keep.
