Vercel's case study documents how Dub, an open-source link management platform, uses Vercel's Domains API and managed infrastructure to handle over 3,000 active domains and 5 million link redirects per month, growing at 25% and 40% month-over-month respectively. The API simplifies reverse proxy setup and SSL certificate issuance, enabling Dub to provision custom domains for users via a single API call.

## Evidence

Verbatim from https://vercel.com/blog/how-dub-grew-to-3000-active-domains-with-vercels-multi-tenant-saas-toolkit:

> Vercel’s powerful API allowed Dub to efficiently manage custom domains from the outset. Vercel simplified the otherwise complex process of setting up reverse proxies and issuing SSL certificates, which allows Dub to easily provision new custom domains on behalf of their users via a simple API call.
