Scheduling and meetings decision
lemcal
A technically competent developer can implement a useful subset (booking pages, calendar sync, reminders) but matching the full polished, integrated SaaS product (scale, reliability, many integrations and UX polish) will take more time and ongoing ops than a simple DIY replacement.

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. All lemcal alternatives, with the arithmetic →
What a replacement has to do
- Allow someone to publish a personal booking page, connect one or more calendars, show available slots, accept bookings (with pre-meeting questions & reminders), and write bookings back to the connected calendar(s).
What it still won’t have
- Polish and UX refinements (branding, custom domains, landing-page polish)
- Scale-tested reliability and uptime guarantees
- Deep native integrations (CRM native integrations listed as “coming soon”)
- Analytics and advanced reporting (detailed statistics shown as higher-tier feature)
- Marketplace trust & brand recognition
What remains hard
- Product polish and ongoing maintenance

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 scheduling service using Next.js for frontend, Node.js/Express for API, Postgres for storage, Redis for job queue, and Fly.io or Vercel for hosting. Implement: OAuth calendar connections (Google and Microsoft), an availability engine that merges calendars and computes free slots, a public booking page generator per user, booking flow that saves bookings to Postgres and creates calendar events via APIs, configurable pre-meeting questions, email reminders via a transactional email provider, and a round-robin assignment for team members. Out of scope: native CRM integrations, payments, advanced analytics dash. Include error handling, retries for webhook failures, tests for calendar sync and availability logic, and deployment scripts.

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.
