  • Apache-2.0
  • No iframes
  • Timezone & DST-correct
  • MCP-ready

Embeds natively, anywhere

A real web component — React wrapper, one-line script, or the raw element. No iframes unless you want them, themeable with CSS variables.

Yours, commercially — Apache-2.0

Clean-room engine and SDK. Ship it inside products you sell with zero copyleft, no commercial license, no strings.

Race-proof booking engine

Timezone- and DST-correct availability with buffers, notice windows and caps — double-bookings are impossible at the database level.
