Where exactly does Dub use Jev?

In malicious-link-check.ts, which runs before a short link is created so a typed Jev verdict gates the URL; the rest of the platform's link attribution features do not depend on it.

Yes, the core is AGPLv3 and self-hostable, though some enterprise features in the /ee directory require a commercial license.

What license exactly applies to which part?

Open core, and the split is stated as roughly 99% core under AGPLv3 with the remaining 1% under a commercial license covering the /ee Enterprise Edition. Enterprise features are built by Dub Technologies' full-time core engineering team, and GitHub's own license metadata reports NOASSERTION rather than a single named license.

What is Dub and at what scale does it run?

The open-source link attribution platform for short links, conversion tracking and affiliate programs, powering more than 100 million clicks and 2 million links a month. Named users include Twilio, Buffer, Framer, Perplexity, Vercel and Laravel.

What does self-hosting actually require?

A Next.js and TypeScript stack with Prisma, Upstash Redis, Tinybird, PlanetScale, NextAuth, BoxyHQ for SAML SSO, Stripe, Resend and Turborepo, deployed on Vercel in the reference setup. The repo recommends node v23.11.0 and pnpm 9.15.9 for local development, with a seed script under apps/web for test data.

What are common local development problems with Dub?

A missing-table error is fixed with `pnpm prisma:push`, which pushes the Prisma schema to the database without migration files. If the project will not build, check that node and pnpm match the recommended v23.11.0 and 9.15.9, then delete node_modules, .next and .turbo in apps and packages and reinstall.

Who maintains Dub, and how do I contribute?

Dub Technologies, Inc. is a commercial open-source company; the /ee enterprise features are built by its full-time core engineering team. Outside contributions go through GitHub issues and pull requests, with a local development guide and a dev seed script under apps/web for test data.

Dub

Watch out

Open-core license: AGPLv3 for the core with commercial terms for the /ee directory (GitHub reports NOASSERTION); the Jev check is a narrow path inside a large platform.
