How to vibe codeCrisp
The AI Customer Support Platform for Every Business

The verdict: can you vibe code Crisp?
Build a scoped personal helpdesk subset rather than paying for enterprise tiers, but brace for heavy backend complexity in wiring real-time WebSockets and RAG agents.
Replicating Crisp means building a multi-tenant shared inbox, embeddable JavaScript chat widgets, real-time WebSocket state machines, and an AI RAG pipeline simultaneously. An AI coding agent will scaffold the Next.js dashboard and Prisma schema instantly, but debugging race conditions in WebSocket connection drops, formatting incoming email parsing edge cases, and managing multi-channel state synchronization will consume weeks of frustrating iteration.
Estimated effort: 3-4 weeks of focused development and debugging
What you can't replicate
- The 100+ native third-party software integrations
- The exact official chat widget script embedded across thousands of production sites
- The brand equity and 11-year operational maturity of a bootstrapped SaaS

The hard parts of vibe coding Crisp
- Maintaining persistent, low-latency bi-directional WebSocket rooms at scale
- Normalizing wildly different omnichannel APIs (WhatsApp, email IMAP/SMTP, Telegram) into a single database schema
- Orchestrating autonomous LLM agents with RAG ingestion pipelines and deterministic fallback states
- Building a lightweight, un-crashable embeddable client-side JavaScript widget script that won't break host sites

Build guide
01Database Schema & Auth Setup
Initialize the Next.js project with Tailwind CSS, Prisma, Neon Postgres, and better-auth for workspace management.
Initialize a new Next.js project with TypeScript, Tailwind CSS, and App Router. Set up Prisma ORM configured for Neon Postgres. Create database models for Workspaces, Users, Conversations, Messages, and Contacts. Implement better-auth for secure email/password authentication linked to workspaces, ensuring multi-tenant isolation where agents only see their workspace conversations.02Shared Inbox Dashboard UI
Build the team inbox dashboard with a three-pane layout for conversation lists, active chat threads, and customer CRM profiles.
Build a responsive team inbox dashboard using Tailwind CSS and shadcn/ui. Implement a three-pane layout: left sidebar for navigation and sub-inboxes, center pane for the active conversation list with status filters (open, pending, closed), and right pane showing the live customer CRM profile, custom attributes, and internal notes. Connect the UI to Prisma backend API routes for fetching and updating conversation statuses.03Real-Time Chat Infrastructure & Embeddable Widget
Create a standalone embeddable chat widget script and set up WebSocket synchronization for live messaging.
Build a lightweight, vanilla JavaScript embeddable chat widget script that can be dropped onto any external website via a single script tag. The widget should render a floating chat bubble, open an interactive chat window, and communicate via WebSockets to a Node.js Socket.IO server hosted on Fly.io. Ensure the backend properly broadcasts incoming visitor messages to the Next.js team dashboard in real time.04AI Support Agent & RAG Pipeline
Integrate an autonomous AI support agent that indexes workspace knowledge base articles and answers customer queries automatically.
Implement an AI support agent feature using the Anthropic API and pgvector in Neon Postgres. Create a Knowledge Base management section where users can add help articles. Build a RAG ingestion pipeline that chunks articles into vector embeddings. When a customer sends a message in the chat widget while no human agent is assigned, automatically query the relevant knowledge base context and generate an AI response via Anthropic Claude.05Omnichannel Email Ingestion & Notifications
Add email integration via inbound webhooks and configure real-time notifications for new support inquiries.
Integrate email channel support by setting up an inbound webhook endpoint (using Resend or Sendgrid webhooks) to ingest customer support emails directly into the shared inbox as conversations. Implement real-time notification toasts in the Next.js dashboard and configure push/email alerts when unassigned conversations receive new messages.06CRM Profiles, Notes, and Polish
Add customer timeline tracking, internal private notes, canned responses, and final UI polish.
Add advanced workspace features including internal private notes on conversations, canned responses (shortcuts) for rapid agent replies, and a customer activity timeline tracking past interactions. Refine error handling, loading states, and responsive design across the entire dashboard application.
