Build me a Developer Tools web app like Whois JSON API. Whois JSON API does: Effortlessly retrieve accurate WHOIS details for any domain with our REST API. Perform bulk WHOIS queries and check URL availability in real time, all in a structured JSON format for seamless integrat It reportedly makes about $2k/mo, so the core idea clearly has demand — I want a lean version I can run and charge for. Start from the open-source project jquense/react-big-calendar (https://github.com/jquense/react-big-calendar) — reuse what fits, strip its branding, and build the specifics below on top of it. Requirements: - Public booking page with availability, time zones, and confirmation emails. - Calendar sync and a dashboard of upcoming bookings. - Buffer times and simple team support. Also: - Clean, modern, responsive UI with a thoughtful landing page. - Email/password auth and a simple paid tier (Stripe test mode) so it's ready to charge. - A README covering setup, environment variables, and how to deploy. Ship a working MVP I can run locally first, then help me deploy it.
