In simple English
This tool lets people pick a time to meet with you through a public web page. It connects to your personal calendar so people cannot book when you are busy. It creates video call links automatically when someone books a slot. It costs nothing to run because it lives on Cloudflare's free tier. You need some patience to set up security credentials with Google or Microsoft before it works.
What it is
An open-source alternative to Calendly built for TypeScript and deployed on Cloudflare Pages with a D1 database. It handles multiple event types, custom buffer times, automated email reminders and OAuth sign-in.
