LinkID is built for developers and professionals.
Stop pasting long URLs everywhere. Share clean, readable links like:
linkid.qzz.io/username/github · linkid.qzz.io/username/linkedin

Features

Core

• Platform Routing — Predictable links like /github, /linkedin, /leetcode, /portfolio
• Single Professional Identity — One username, all your platforms
• Auto Platform Detection — Paste any URL and the platform is detected automatically
• Public Profile Page — Shareable profile at linkid.qzz.io/username
• Real-time Dashboard — Add, edit, and delete links instantly without a page reload

🧩 Chrome Extension

• Auto-Fill Applications — Bypass strict Applicant Tracking Systems (ATS) by automatically injecting your original, raw platform URLs into job application fields.
• OAuth Integration — Securely connects with your LinkID profile in one click.
• Source Code — Available in its own repository: vishnukothakapu/linkid-extension.

Auth & Security

• OAuth Login — Google & GitHub sign-in via NextAuth.js
• Email + Password Auth — Traditional credential-based login with bcrypt hashing
• Route Protection — Middleware-based auth guards on dashboard and API routes

UX & Design

• Dark Mode — Full system, light, and dark theme support via next-themes
• Fully Responsive — Mobile-first design with Tailwind CSS
• Toast Notifications — Instant feedback on all user actions
• Platform Icons — Automatic icon matching for 10+ platforms

Developer Experience

• Type-safe — End-to-end TypeScript with strict mode
• Prisma ORM — Type-safe database access with PostgreSQL
• URL Validation — Strict per-platform URL validation before saving
• Optimistic UI — Local state updates before server confirmation

Installation

Prerequisites

• Node.js >=20.9.0
• PostgreSQL >=14
• npm / yarn / pnpm

1. Clone the Repository

git clone https://github.com/vishnukothakapu/linkid.git
cd linkid
npm install

2. Configure Environment Variables

cp .env.example .env

Edit .env with your values:

# Database
DATABASE_URL="postgresql://user:password@localhost:5432/linkid"

# NextAuth
NEXTAUTH_SECRET="your-secret-here"          # openssl rand -base64 32
NEXTAUTH_URL="http://localhost:3000"

# OAuth Providers (optional but recommended)
GOOGLE_CLIENT_ID="your-google-client-id"
GOOGLE_CLIENT_SECRET="your-google-client-secret"

GITHUB_CLIENT_ID="your-github-client-id"
GITHUB_CLIENT_SECRET="your-github-client-secret"

Tip: Generate NEXTAUTH_SECRET with openssl rand -base64 32

3. Set Up the Database

# Run migrations
npx prisma migrate dev

# If migrations aren't working as expected, check /prisma/migrations find the latest init migration. Mark migrations before that as applied using :
npx prisma migrate resolve --applied <migration_name>

# (Optional) Open Prisma Studio to inspect data
npx prisma studio

Docker Setup (optional)

docker-compose up -d   # starts PostgreSQL
npx prisma migrate dev
npm run dev

4. Start the Development Server

npm run dev

Open http://localhost:3000 🎉

3. Toggle Developer mode to ON (in the top right corner).
4. Click the Load unpacked button (top left corner).
5. Select the linkid-extension folder you downloaded.
6. Open the extension from your toolbar, click Connect LinkID, and you're ready to auto-fill!

1. Sign up at linkid.qzz.io/register
