Scheduling and meetings decision
Appointlet
A usable, smaller scheduling replacement is realistic for a competent developer to build and maintain; Appointlet's features are achievable without proprietary moats, though reproducing every integration and polish will take extra time.

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
- Provide a public scheduling page, show available times from connected calendars, accept a booking, create calendar events and send confirmations/reminders
What it still won’t have
- Built-in web conferencing integrations (Zoom, Meet, MS Teams, WebEx, GoToMeeting, Join.Me)
- Prebuilt CRM & Salesforce integration
- Zapier integrations and many third‑party connectors
- Polished white‑labeling and branding controls out of the box
- Prebuilt round-robin/team scheduling behavior
What remains hard
- Product polish and ongoing maintenance

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 1 seat.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a self-hosted appointment scheduler using Node.js (Express), Postgres, and React. In scope: user accounts, OAuth calendar sync (Google + Office 365), public scheduling pages with time-zone handling and embedded widget, booking creation with conflict checks, email confirmations and programmable reminders (SendGrid), simple admin dashboard to view/filter/cancel/reschedule bookings, webhooks for downstream integrations, and unit/integration tests. Out of scope: ready-made Zoom/MS Teams SDK integrations, multi-tenant SaaS billing, and advanced analytics. Include error handling, input validation, and CI tests.

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.
