Drop-in rules files that teach AI coding assistants your stack's conventions, patterns, and gotchas. 10 stacks. 1,800+ lines of battle-tested rules.
One-time purchase. All 10 stacks. Free updates for 1 year.
// AI suggests Pages Router pattern in App Router project
export async function getServerSideProps() {
const data = await fetch('/api/posts')
return { props: { data } }
}
// Uses default export, any types, no metadata
export default function Page(props: any) {
return <div>{props.data.map(x => ...
// AI uses correct App Router patterns
export async function generateMetadata() {
return { title: 'Blog', description: '...' }
}
// Server Component, typed props, proper data fetching
export default async function BlogPage() {
const posts = await getPosts()
return <PostList posts={posts} />
Each rules file is 150-250 lines of real, specific patterns — not generic advice. Written by developers who ship with these stacks daily.

Your AI now uses the right patterns, APIs, and conventions for your stack.
./install.sh nextjs
That's it. One command.
Tells the AI exactly which version and features you're using
File structure, naming conventions, where code belongs
Copy-paste patterns for the most common operations
Explicit "Don't" rules prevent the most common AI mistakes
Framework-specific pitfalls that even experienced devs miss
Updated for 2025: Next.js 15, React 19, Svelte 5, Pydantic v2
One purchase. All stacks. All tools.
Instant download. No subscription. No account needed.
Absolutely. But a good rules file takes 2-4 hours to write and test per stack. DevRules Pro gives you 10 stacks for the price of one lunch. Plus we keep them updated as frameworks release new versions.
Cursor (.cursorrules), Claude Code (CLAUDE.md), Cline (.clinerules), and Windsurf (.windsurfrules). The installer handles the file naming for you.
Yes. They're plain text files. Add your project-specific rules at the bottom, remove what you don't need, or use them as a starting point for your own rules.
We're adding new stacks regularly. Email us your request and we'll prioritize it. Current roadmap: Django, Rails, Go/Gin, Remix, Tauri.
Yes. Your purchase includes 1 year of updates. When Next.js 16 drops or Svelte 6 ships, you get the updated rules.
Yes — 30-day money-back guarantee. If the rules don't improve your AI coding experience, we'll refund you. No questions asked.
One file. One command. Your AI finally writes code the way you would.
