Automation and integrations decision
Bookedin
A small technical team can implement a narrow self-hosted workflow (LLM-driven SMS/calls + calendar booking + inbox) in ~30 hours, but reproducing BookedIn's full no-code builder, white-label portal, templates, and support-led onboarding is a larger product effort better served by staying on the platform.

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
- Accept lead -> engage via SMS/voice/email using an LLM-driven agent -> check availability and create calendar booking -> send confirmations and reminders -> record event in unified inbox/analytics.
What it still won’t have
- No-code visual drag-and-drop agent/workflow builder
- White-label client portal and branding controls
- Pre-built templates and onboarding that speed deployment
- Priority/premium support and 1:1 strategy calls
- Credits marketplace and built-in multi-provider token billing
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a self-hosted minimal BookedIn replacement using Node.js (Express), Postgres, React, OpenAI (or Claude) for agent text generation, and Twilio for voice/SMS. Core features in scope: (1) ingest leads via web webhook and CSV upload, (2) LLM-driven SMS/email agent flow with configurable prompt templates, (3) Twilio integration to send/receive SMS and place TTS calls, (4) Google Calendar integration to check availability and write bookings, (5) a simple web UI showing unified inbox and appointment list, (6) basic analytics dashboard (leads -> booked conversion). Out of scope: visual drag-and-drop workflow builder, white-label client portals, multi-tenant billing/credits marketplace, and enterprise SLA. Include error handling for external API failures, retries, idempotency for lead ingest, input validation, and automated tests (unit tests for core logic and end-to-end tests for webhook -> booking flow). Provide Docker Compose for local dev and a deployment guide for a single small VPS (or managed Postgres + Vercel hosting).

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.
