How to vibe codeCopper
The CRM that lives in Google Workspace and your browser extension

The verdict: can you vibe code Copper?
Build a subset with a web dashboard, but the Chrome extension DOM injection and Google Workspace sync will require weeks of frustrating debugging.
Copper's core value is not its CRUD database; it's the invisible friction reduction provided by its Chrome extension injecting directly into Gmail and Google Calendar, alongside real-time bi-directional Google API syncing. An AI coding agent can scaffold the Next.js CRM dashboard and SQLite database in an afternoon, but handling Google OAuth token refreshes, background webhook queues, and maintaining a resilient Manifest V3 extension sidebar that survives Gmail DOM updates will turn into a multi-week engineering ordeal.
Estimated effort: 4-6 weeks of dedicated development and extension debugging

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js project with Tailwind CSS and configure Turso with Drizzle ORM to establish core CRM models.
Create a new Next.js project using the App Router, TypeScript, and Tailwind CSS. Initialize Drizzle ORM configured for Turso (SQLite). Create database schemas for users, contacts (with custom fields), companies, sales_pipelines, pipeline_stages, deals, projects, tasks, and activity_feed. Set up relations and foreign keys correctly. Include migration scripts and a seed script with sample agency clients and sales stages.02Authentication & User Management
Implement authentication using better-auth to secure the CRM dashboard and manage user sessions.
Install and configure better-auth in the Next.js application using Turso as the database adapter. Implement email/password signup and Google OAuth login to align with the workspace theme. Create protected layout wrappers for the dashboard routes (/dashboard), and build clean sign-in and sign-up pages using Tailwind CSS and shadcn/ui components. Handle session cookies and secure API route handlers against unauthenticated access.03CRM Core: Contacts & Visual Pipelines
Build the core CRM views including contact management tables and drag-and-drop sales pipelines.
Build the core CRM interface inside the Next.js dashboard. Implement a contacts list view with filtering, search, and a detail drawer displaying timeline activities, notes, and associated deals. Create a visual drag-and-drop sales pipeline board (Kanban style using @dnd-kit) where deals can be moved across custom stages, updating deal values, win probabilities, and triggering activity logs automatically.04Project Management & Task Delivery
Add post-sale project workflows and centralized task lists to bridge sales closures with client service delivery.
Develop a project management module in the dashboard allowing users to convert closed deals directly into active projects. Build a project workflow view with status columns, milestone tracking, file attachments, and a centralized task list view with due dates, assignees, and recurring task automation triggers. Ensure all tasks and project updates tie back to the parent contact and company records.05Google Workspace API Integration
Implement Google OAuth and API background sync for Gmail, Google Calendar, and Google Drive.
Implement server-side integration with the Google Workspace APIs (Gmail, Calendar, Drive). Create OAuth token exchange flows allowing users to connect their Google accounts. Build background sync jobs that fetch recent email threads and calendar events associated with contact email addresses, storing them in an activity_feed table. Add endpoints to attach Google Drive files directly to CRM deal and contact records.06Chrome Extension Manifest V3 Development
Build a companion Chrome extension that injects a sidebar into Gmail to display matching CRM contacts and deals.
Create a Chrome extension using Manifest V3 in a separate /extension directory within the repo. Configure a background service worker, a popup script, and a content script designed to inject a collapsible sidebar panel into Gmail (mail.google.com). The content script must parse the email address of the currently open message thread, query the Next.js backend API for matching CRM contact and deal data, and render a clean React-based sidebar allowing the user to create notes, log tasks, or add leads directly from their inbox.07Activity Feed & Polish
Integrate global activity feeds, custom reporting widgets, and final UI error handling.
Build a global activity feed dashboard page showing a chronological timeline of all team actions, email logs, completed tasks, and stage changes across all contacts and deals. Add a reporting tab with charts (using Recharts) tracking total pipeline volume, win rates, and team activity counts. Perform a comprehensive code review, add error boundaries, ensure responsive design across all dashboard pages, and write README instructions for setting up Google OAuth redirect URIs and Chrome extension local loading.
