Hello again Hacker News! Incredibly excited to be launching Platforms Starter Kit 2.0 on here.

For context: Multi-tenant applications serve multiple customers across different subdomains/custom domains with a single unified codebase.

With the Platforms Starter Kit, you can offer unlimited custom domains at no extra cost to your customers as a premium feature, without having to worry about custom nameservers or configuring SSL certificates.

Ever since we launched the first version of this starter kit a year ago, we've seen many platforms scale to hundreds of thousands of custom domains on Vercel:

◆ Hashnode ◆ Super.so ◆ Incident.io ◆ Mintlify ◆ Dub.sh

With the new version – now built with the Next.js 13 App Router – we cannot wait to see what kind of platforms you build with it! Excited to hear your feedback!
