Dub

Dub is the open-source link-management platform — a modern, self-hostable alternative to Bitly. It provides branded short links, QR codes, deep click analytics, and a powerful API, making it the backbone for marketing attribution and link-based products.

Market opportunity

Bitly charges $8–$300+ per month and gates analytics and custom domains behind higher tiers. Short links are core marketing infrastructure (campaigns, affiliate tracking, social), so a developer-friendly open-source option with a real API is well positioned for both internal use and resale.

Technical overview

• Stack: TypeScript + Next.js, with MySQL (PlanetScale), Redis, and Tinybird for analytics; built to run on edge infrastructure for fast redirects.
• API-first: create and track links programmatically — ideal for embedding link features into other apps.
• Features: custom domains, QR codes, click analytics, geo/device targeting, and team workspaces.

Who's it for

Marketing teams, affiliate marketers, and developers building link/attribution features into their own products.

Get started

Use the hosted app at dub.co, or self-host:

git clone https://github.com/dubinc/dub
cd dub
pnpm install
cp .env.example .env   # configure database, Redis, and your domain
pnpm dev

Add a custom domain, create a short link, and read click analytics in the dashboard or via the API.
