Customer support decision
Groove
A capable engineer can build a narrow subset (inbox + RAG-driven drafts + routing) cheaply, but reproducing Helply's full platform (many integrations, ROI attribution, enterprise onboarding, and production polish) is a much larger effort better suited to buying.

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
- Receive customer messages, assemble account+KB context, generate AI draft or automated resolution, apply routing/escalation and record ticket outcomes
What it still won’t have
- Per-ticket billing, enterprise contracts and onboarding handled by vendor
- Pre-built integrations and connectors to many B2B systems
- Vendor-provided ROI tracking, SLAs, and hands-on onboarding
- Polish, monitoring, and reliability of a production SaaS platform
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 minimal AI-native B2B support system using Node.js (Express), Postgres, and a retrieval-augmented LLM (OpenAI or compatible). In scope: (1) ingest email and a web chat webhook into a unified inbox; (2) fetch and attach account context from a mock CRM (Postgres table) and KB (vector index using pgvector); (3) implement RAG + prompt templates to produce reply drafts and a confidence score via the LLM API; (4) apply simple routing rules to assign or escalate tickets and tag churn/upsell signals; (5) record tickets, replies, and signals in Postgres and provide a small web UI to review drafts and send replies. Out of scope: enterprise billing, per-ticket metering UI, dozens of third-party connectors, advanced analytics dashboards. Include error handling, retries for external APIs, and unit tests for ingestion, RAG retrieval, and routing logic.

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.
