OpenCalendly

Live site: opencalendly.com

OpenCalendly is an open-source scheduling app for teams that want Calendly-class booking flows without giving up runtime ownership. It ships public booking pages, team scheduling, embeds, organizer tooling, calendar sync, analytics, and the operational guardrails needed to run the stack yourself.

What It Does

• One-on-one and team booking flows with conflict-safe booking commits
• Cancel and reschedule links for invitees
• Organizer console for event types, availability, teams, webhooks, and calendars
• Analytics dashboard, embed playground, and webhook delivery runners
• Google and Microsoft calendar sync plus calendar writeback

Stack

• apps/web: Next.js App Router on Cloudflare Pages
• apps/api: Hono API on Cloudflare Workers
• packages/db: Drizzle + Neon Postgres
• packages/shared: shared Zod schemas and TypeScript types
• Auth and email: Clerk + Resend

Neon is the only supported database provider for this repository because the local and production setup is built around the current Hyperdrive integration path.
