Automation and integrations decision
SetSmart
A competent developer can implement a narrow, self-hosted DM-to-booking workflow (the core loop) in a few weeks using available APIs and an LLM, but reproducing SetSmart's polished multi-channel reliability, billing/top-up logic, analytics, and support is a larger effort better suited to buying the SaaS for production usage.

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Accept inbound DM → classify/qualify lead with LLM → propose available times → create booking and confirm via channel API → persist lead and conversation
What it still won’t have
- Polished multi-channel reliability and scaling (throttling, rate-limit handling, retry logic)
- Proprietary AI tuning and conversation-engine optimizations claimed as SetSmart Advanced
- Built-in live chat support and onboarding help
- Pre-built templates, UX and rapid iteration from an existing product team
- Message-count billing / top-up management and built-in analytics dashboard
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a self-hosted AI appointment-setter for Instagram DMs and WhatsApp using: FastAPI backend, Postgres, Redis (for rate limiting/conversation state), React admin UI, and Docker. In scope: webhook receivers for Instagram and WhatsApp, message normalization, conversation state storage, LLM integration (OpenAI/Anthropic) with prompt templates, calendar integration with Calendly/Cal.com (create bookings and query availability), send replies via channel APIs (template/regular messages and optional voice notes), admin UI to view conversations/lead tagging/analytics, automated retry and rate-limit handling, and unit + integration tests. Out of scope: building a custom LLM, paid third-party managed hosting. Require robust error handling, logging, retries, rate-limit backoff, and tests for webhook handling, booking creation, and LLM prompt-response flow.

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.
