ShipKit: The Next.js Boilerplate Built for AI Coding Tools
ShipKit is not a UI theme. It is not a component library. It is a configuration layer for Next.js projects that makes AI coding tools work better from day one.
Here is what that means in practice.
What ShipKit includes
ShipKit ships as four stack configurations. Each one is a folder you drop into an existing project or use to start a new one. Every configuration includes:
- A
CLAUDE.mdfile tuned for that stack - A
.cursorrulesfile with the same conventions - A documented project structure the AI can navigate
- Rules for where code goes, what patterns to use, and what to avoid
The four configs cover the most common Next.js setups: full-stack with a database, API-only backend, marketing site, and admin dashboard. Pick the one that matches what you are building.
Why a CLAUDE.md file matters
Claude Code reads CLAUDE.md at the start of every session. Cursor reads .cursorrules continuously as you work. How to set up .cursorrules for Next.js covers writing them from scratch if you want to understand what goes in them before buying. These files give the AI your conventions instead of making it guess.
Without them, an AI coding tool falls back on general Next.js patterns. Those patterns are reasonable. They are not yours. The result is output you spend time redirecting: wrong file locations, hardcoded strings, component files that mix rendering with state management.
With a well-written context file, the first suggestion is usually close. The edits are smaller. The review is faster.
ShipKit vs. a standard Next.js boilerplate
A standard Next.js boilerplate gives you a project that runs. ShipKit gives you a project that an AI can work in without constant correction.
The difference shows up across a session. A standard boilerplate produces consistent output for the first few prompts, then drifts as the AI fills in gaps with its own defaults. ShipKit keeps the output consistent across longer sessions because the conventions are explicit, not implied.
This is not a theoretical difference. It is the difference between a session where you are building and a session where you are fixing.
What ShipKit does not include
ShipKit is a configuration product. It does not include:
- UI components
- Styled pages
- Authentication flows
- A design system
For those, ShipUI themes are the companion product. Every ShipUI theme is built on the same conventions ShipKit documents. The CLAUDE.md in ShipKit and the architecture in a ShipUI theme are consistent on purpose.
You can use ShipKit alone with your own codebase. You can use a ShipUI theme alone without ShipKit. Buying a ShipUI theme with the bundle option includes both.
Who it is for
ShipKit is useful if you are:
- Starting a new Next.js project and want AI tools to be productive from the first prompt
- Working on an existing project and want to add structure that helps Claude Code or Cursor give better output
- On a team where multiple people use AI coding tools and you want consistent conventions
It is not useful if you do not use AI coding tools. The value is entirely in the context files and the documented conventions.
Getting started
ShipKit is a one-time purchase at $10, standalone or bundled with any ShipUI theme. After purchase you get a download link. Unzip, pick a stack config, drop the files into your project root.
# After download, in your project root:
cp ShipKit/nextjs-marketing/CLAUDE.md .
cp ShipKit/nextjs-marketing/.cursorrules .
Open the files and read them before you start. They document the conventions you are committing to. Adjust anything that conflicts with decisions you have already made, then start building.
