Modern customer support & feedback platform

The verdict: can you vibe code Featurebase?
You can build a functional personal clone of Featurebase's core modules, but the omnichannel inbox synchronization and AI RAG pipeline require rigorous multi-system wiring.
Featurebase combines five distinct products into one suite: a help desk, a feedback board, a roadmap, a changelog, and a help center. While building each CRUD module individually is straightforward with AI coding tools, orchestrating the real-time websocket chat streams, configuring robust RAG vector search for the AI agent, and embedding cross-origin widgets without layout shifts will expose painful edge cases in state management and security headers.
Estimated effort: 3-4 weeks of focused development
What you can't replicate

The hard parts of vibe coding Featurebase
- Synchronizing real-time bi-directional messaging streams (chat widgets, email threads, live socket connections)
- Building a reliable RAG pipeline for the AI support agent over dynamic knowledge base articles with accurate prompt context
- Developing a lightweight, secure cross-origin embeddable JavaScript widget that renders cleanly in third-party web apps without style leaks

Build guide
01Database Schema & Authentication Setup
Initialize a Next.js project with Tailwind CSS, configure better-auth with Postgres via Neon, and set up the core relational schema for users, workspaces, tickets, feedback posts, roadmap columns, and help articles.
Create a new Next.js TypeScript project with Tailwind CSS. Set up better-auth connected to a Neon Postgres database using Drizzle ORM. Define database schemas for: workspaces, users, tickets (with status, priority, channel), feedback_posts (with vote count and category), roadmap_items (linked to feedback), help_articles (with markdown content and vector embedding column for RAG), and changelogs. Implement secure multi-tenant isolation by workspace ID across all tables.02Omnichannel Unified Support Inbox
Build the support agent dashboard with real-time ticket triage, conversation threading, internal notes, status assignment, and filtering by customer revenue or priority.
Build the support agent inbox interface using Tailwind CSS and shadcn/ui. Create a master-detail layout listing tickets with filters for status (open, pending, resolved), assignee, and priority. Implement real-time conversation threading with message bubbles for user queries and agent replies, support for internal private notes visible only to team members, and a sidebar showing mock customer metadata and lifetime value.03AI Support Agent & Knowledge Base RAG Pipeline
Implement the RAG-powered AI agent ('Fibi AI') that searches help center articles using pgvector embeddings and automatically drafts or resolves customer inquiries.
Implement an AI support agent API route using the Anthropic API and pgvector in Neon. When a customer submits a new ticket or live chat message, generate an embedding of the query, perform a similarity search against help_articles table chunks, and prompt Claude to generate an accurate response grounded strictly in the documentation. Include a confidence score and human-hand-off trigger if the confidence is low.04Feedback Portal & Voting System
Build the public feedback board where users can submit feature requests, upvote ideas, add comments, and filter by status.
Create a feedback portal module allowing authenticated users to submit feature requests with a title, description, and category tag. Implement an upvoting mechanism with optimistic UI updates that prevents duplicate votes per user. Add sorting options for trending, top-voted, and most recent ideas, along with a comment thread section for each post.05Visual Product Roadmaps & Changelog Publishing
Build a kanban-style roadmap board synchronized with feedback statuses and a changelog publishing interface for release notes.
Build a visual kanban product roadmap board with columns for 'Planned', 'In Progress', and 'Complete' that syncs directly with feedback posts and roadmap items. Build a companion changelog publishing tool with a rich-text editor that allows admins to publish release notes to a public feed and trigger automated email notifications to upvoted users.06Embeddable Widget SDK
Develop a lightweight, embeddable JavaScript widget script that mounts a chat launcher, help center search bar, and feedback tab on external sites.
Build a standalone embeddable JavaScript widget bundle using React and iframe encapsulation that third-party sites can load via a single script tag. The widget must render a floating launcher button in the bottom right corner, opening a modal drawer with tabs for live chat, instant help center search, and quick feature request submission, communicating securely via postMessage with the main Next.js backend.

Vibe code Featurebase: FAQ
- Can you vibe code Featurebase yourself?
- Solid side project — 62/100 vibecodeable. You can build a functional personal clone of Featurebase's core modules, but the omnichannel inbox synchronization and AI RAG pipeline require rigorous multi-system wiring.
- How long does it take to vibe code Featurebase?
- 3-4 weeks of focused development — roughly 45-60 hours of hands-on time with an AI coding agent.
- How do you build your own Featurebase?
- Scoped to personal use: Next.js with Tailwind CSS and shadcn/ui on the front, Next.js App Router API routes & Server Actions behind it, Neon (Serverless Postgres with pgvector) for data. Follow the 6-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own Featurebase without being an expert?
- Use an AI coding tool (Claude Code or Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 3-4 weeks of focused development. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Featurebase instead of paying?
- About ~$12 one-time to start and ~$10-25/mo to run, versus $59/seat/mo (Professional) for Featurebase. Break-even: Instant if replacing multiple support and feedback subscriptions for personal projects.
- What stack should you use to vibe code Featurebase?
- Next.js with Tailwind CSS and shadcn/ui; Next.js App Router API routes & Server Actions; Neon (Serverless Postgres with pgvector); plus Resend for transactional emails, Anthropic API for Fibi AI support agent.
