Can I vibe code NetHunt CRM?

CLONE — YOU CAN REBUILD THE FEATURE

When paying for NetHunt, you pay for a polished Chrome sidepanel, pre-configured Gmail API webhooks, and an email automation engine. The underlying database engine—storing deals, contacts, custom fields, and stage transitions—is standard CRUD. Building this internally for a fixed team bypasses the need for Google's public OAuth verification process. The main maintenance burden lies in updating Chrome extension DOM selectors if Google changes Gmail layout elements, or using standard Workspace Apps Script cards instead.

NetHunt CRM

01

Why this verdict

NetHunt CRM is essentially a structured database with a Chrome extension and Google Workspace SDK UI overlaying Gmail. For an internal team, building a custom Chrome Extension sidepanel connected to Supabase and Gmail APIs provides identical core functionality without per-seat fees.

The one-shot build promptbuild it on Lovable
Build a custom, full-stack Gmail-integrated CRM replacement for NetHunt CRM using Next.js 14, Supabase (PostgreSQL), and a Chrome Extension (Manifest V3).

1. DATA MODEL (Supabase):
- `contacts`: id, email (unique), full_name, phone, company_id, custom_fields (jsonb), created_at.
- `companies`: id, name, domain, created_at.
- `deals`: id, title, value (decimal), stage_id, contact_id, company_id, custom_fields (jsonb), updated_at.
- `pipeline_stages`: id, name, position, color_code.
- `email_logs`: id, message_id (Gmail thread ID), contact_id, direction (inbound/outbound), subject, snippet, sent_at.

2. CORE CRM BACKEND (Next.js App Router API):
- CRUD API for contacts, companies, deals, and pipeline stages.
- Webhook endpoint receiving Google Cloud Pub/Sub notifications for Gmail sync.
- Endpoint to automatically parse incoming emails, match sender email against `contacts`, link thread to open `deals`, or auto-create a contact if missing.
- Pipeline status trigger engine: execute automated email template sending when a deal stage changes.

3. CHROME EXTENSION (Manifest V3 - Sidepanel API):
- Context-aware UI that reads active Gmail email address from the DOM / Google API.
- Sidepanel displays matched contact info, active deals, and interaction history.
- Quick actions inside sidepanel: Create Deal, Change Stage, Add Note, Assign Custom Field.
- Auth flow using Google OAuth 2.0 PKCE pattern directly communicating with Supabase Auth.

4. SECURITY & ERROR HANDLING:
- Robust retry mechanism for Google Gmail API rate limits (429 handling).
- Ensure strict Row-Level Security (RLS) policies in Supabase so users only view team workspace data.
- Handle detached Gmail threads cleanly with fallback search by recipient email.

5. OUT OF SCOPE:
- Public Chrome Web Store release flow (target unpacked developer load for internal team).
- Complex multi-currency support.

FAQ

+Can I really replace NetHunt CRM with an AI-generated app?

YES — IT IS A GMAIL EXTENSION WRAPPING A POSTGRES DATABASE. NetHunt CRM is essentially a structured database with a Chrome extension and Google Workspace SDK UI overlaying Gmail. For an internal team, building a custom Chrome Extension sidepanel connected to Supabase and Gmail APIs provides identical core functionality without per-seat fees. An MVP takes roughly 1 week; matching the product properly is closer to 2-3 months, due to Google OAuth security review and extension DOM maintenance.

+How long does it take to rebuild NetHunt CRM?

A usable internal version: 1 week. A version you would sell or bet a business on: 2-3 months, due to Google OAuth security review and extension DOM maintenance, mostly spent on managing google oauth refresh tokens securely per seat.

+What do you actually lose by leaving NetHunt CRM?

Pre-packaged Google Workspace Add-on requiring zero setup Maintained Chrome extension updated against Gmail layout changes Native pre-built integrations with Zapier and Looker Studio

+Is it legal to build a NetHunt CRM alternative?

Building a competing product with your own code is normal competition. Copying their code, trademarks, brand assets or scraping their platform is not. Use the prompt to build your own implementation of common features.
