Project and task management decision
Setmore
A capable developer can implement a useful replacement (booking page, calendar, reminders, payments) in ~one week and small ongoing maintenance; Setmore’s scale, integrations catalogue, native apps and support are costly to replicate.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Publish a Booking Page that lists services and availability; customer selects a service/time and provides contact details; store the appointment in a calendar database and show it on a staff calendar; send confirmation and reminder emails/SMS; optionally collect payment at booking.
What it still won’t have
- Mobile desktop apps (native Windows/macOS/iOS/Android) and polished UI upkeep
- Built-in integrations catalogue (Zoom, Facebook, Instagram, Square, Salesforce, etc.)
- 24/7 human support / Live Receptionist service
- Enterprise features and dedicated onboarding/priority support
- Advanced analytics and built-in SEO/growth services
What remains hard
- Execution quality
All customers receive around-the-clock support from Team Setmore.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal appointment-scheduling service using: React (booking page), Node.js + Express (API), Postgres (appointments & users), Stripe (payments), SendGrid (email), Twilio (optional SMS). Implement: public booking page with service menu and real-time availability checks; API endpoints to create/update/cancel appointments with anti-double-booking locking; staff admin calendar view and simple auth for staff; confirmation + customizable reminder emails and a configurable reminder schedule; Stripe payment collection at booking. Out of scope: native mobile apps, enterprise multi-tenant billing, built-in marketplace integrations (Zoom/Facebook). Include input validation, error handling, logging, and automated tests (unit tests for API and end-to-end test for booking flow). Provide Dockerfiles and deployment instructions for a single VPS (DigitalOcean) and a script to run migrations and seed example services and staff.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
