Scheduling and meetings decision
SavvyCal
A competent developer can build a useful single-user scheduling link service (calendar integration, booking flow, notifications) in about a week, but reproducing SavvyCal's full team modes, workflows, branding, and polish is more work—so build a narrow replacement or keep paying for the complete product.
Visit website↗Open-source builds that already do this
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
- Host public scheduling links that read a connected calendar (Google Calendar), show available slots, allow a visitor to pick a time, create a calendar event on the organizer's calendar, and send confirmation emails/webhooks.
What it still won’t have
- Polished team scheduling modes (collective/round-robin/group) at parity
- Built-in workflows/reminders UI and reusable automation templates
- Custom domains, white-labeling, and remove-branding controls
- Calendar overlay UI and browser extension convenience
- Official support, uptime guarantees, and 30-day money-back policy
What remains hard
- Product polish and ongoing maintenance

Keep paying
Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 4 seats.

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a single-user scheduling service using React for the frontend, Node.js/Express for the API, Postgres for storage, and deploy on a single DigitalOcean droplet (or Heroku). Implement: (1) Google OAuth + Calendar free/busy read and event creation, (2) a responsive weekly availability UI that generates selectable slots, (3) backend booking endpoint that atomically creates events and prevents double-booking, (4) transactional email confirmations and reminders (e.g. SendGrid), (5) optional Stripe payment flow to require payment before finalizing a booking, (6) webhooks to notify third-party services. Out of scope: multi-user team pooling/round-robin scheduling UI, browser extension, advanced workflows engine, and enterprise admin features. Include error handling for API failures and race conditions, basic unit and integration tests for booking and calendar flows, and Dockerfiles for deployment.

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.
