Introduction

Versioned @isotopekit/* packages for auth, orgs, billing, and agency — documented for humans and agents.

IsotopeKit is a package-composed Next.js SaaS kit. You own a thin app; capabilities ship as versioned packages you compose and upgrade by semver.

What lives here

Section	Purpose
Getting started	Install, compose packages, run the starter
Packages	Reference for `@isotopekit/*` modules

Mental model

apps/starter     → thin Next.js app you own
packages/*       → versioned capabilities (auth, billing, orgs, …)
_docs / AGENTS.md → agent-readable specs that ship with the kit

Compose what you need. Skip what you don't. Upgrade packages without re-merging a fork.

Next steps

Get started with the starter app
Browse packages for the modules you will compose
Prefer package READMEs and _docs specs when an agent needs deeper detail
