Appointlet?
BUILD FIRST
- One specific customer type and one primary use case
- A vertical slice that completes the main job without manual workarounds
- Visible limits, review steps, and a fallback when an external dependency fails
LEAVE FOR LATER
- Broad third-party integrations
- High-scale collaboration, syncing, and permissions
- Automation that can cause harm without human review
RESEARCH NOTES
What this tool actually does.
Appointlet is an online appointment scheduling SaaS for individuals and teams. Users create customizable booking pages with brand colors, logo, welcome message, and custom forms, then share a scheduling link or embed on any website via code snippet (inline or pop-up). Core features: Google/Outlook calendar sync to prevent double-booking, automatic invites and reminders, web conferencing room creation, manual approval of meeting requests, minimum-notice rules, and buffers. Team capabilities: workspace with permissions, round-robin/pooled availability with optional priority weighting, attendee-chooses-host, and co-hosted meetings checking all hosts' calendars. Bookings can be filtered by team/member/meeting type and exported to CSV. Cancellation/rescheduling notifies attendees. Integrations cover email calendars, video conferencing, CRM, and payments. White-labeling removes branding; 2FA v
RESEARCHED BUILD PROMPT
Give this to your coding agent.
Build a production-style open-source replacement for Appointlet, focusing on the core workflow: an admin creates one or more scheduling pages (each with its own duration, buffer, notice window, timezone display, welcome message, and custom form fields), then shares a public link or embeds the page on a website. Attendees pick an available slot; the system checks the connected Google/Outlook calendar for conflicts, prevents double-booking, and on confirmation creates a calendar event, sends email invites/reminders, and optionally spins up a Zoom/Meet/Jitsi room. Admin can approve bookings manually, cancel/reschedule with attendee email notifications, set minimum notice and buffers, and view/filter/export bookings as CSV. Team mode adds members, roles/permissions, round-robin weighted distribution, attendee-chooses-host, and co-hosted meetings when all hosts are free.
Tech stack: Next.js + TypeScript, PostgreSQL with Drizzle/Prisma, tRPC or REST, Tailwind UI, Nodemailer/Resend for emails, Google Calendar API / Microsoft Graph for calendar sync, NextAuth with Google/Office 365 2FA. Use a message queue (BullMQ/Redis) for reminders. Implement webhook endpoints for calendar and video-provider events. Include a seed script and docker-compose for local dev.
Do not copy Appointlet's brand, logo, copy, or visual design — build a distinct, clean, accessible UI. Out of scope: native mobile apps, multi-language support, complex billing (Stripe integration can list a simple pay-at-booking link), SSO/SAML, and a full no-code page builder. Deliver a README covering setup, environment variables, cron/queue requirements, and known limitations (e.g., timezone edge cases, calendar API quotas).
