Cursor Rules Mega Pack: 30+ Rules for Every Framework

30+ Cursor Rules for Every Stack. One Pack.

Free .cursorrules files are everywhere. They are also too generic to be useful. They cover surface-level patterns but miss the framework-specific gotchas that cause real bugs -- Tailwind CSS v4 dropping tailwind.config.js, Next.js 15 changing async params, Prisma's new type-safe client API.

The Cursor Rules Mega Pack fixes this. 30 expert-crafted .mdc rule files + 5 master .cursorrules configurations covering 10+ frameworks, 5 databases, 4 testing tools, and more. Install the rules that match your stack. Cursor generates correct, idiomatic code from the first prompt.

What's Inside

35 files organized into 7 categories. Pick the rules that match your stack.

• Frameworks (10 rules) -- Next.js 15, React, React Native/Expo, Vue 3/Nuxt 3, FastAPI, Django, Express, Go/Gin, Rails, Laravel
• Databases (5 rules) -- Supabase, Prisma, Drizzle, SQLAlchemy, MongoDB/Mongoose
• Payments (2 rules) -- Stripe, LemonSqueezy
• Styling (2 rules) -- Tailwind CSS v4, CSS Modules
• Testing (4 rules) -- Jest/Vitest, pytest, Playwright, Cypress
• Languages (4 rules) -- TypeScript, Python, Go, Rust
• DevOps (3 rules) -- Docker, GitHub Actions, Vercel/Cloudflare
• Master Files (5 files) -- Stack-specific .cursorrules for common full-stack combos

Every rule file includes:

• Framework-specific conventions -- The exact patterns your stack expects, not generic advice.
• Code examples -- Concrete "do this, not that" samples so the AI sees the correct pattern.
• Anti-patterns -- Explicit rules for what Cursor should never generate (outdated APIs, deprecated patterns, common mistakes).
• Glob-based activation -- Rules activate only for relevant files, reducing noise and token usage.

The 5 Master .cursorrules Files

Each master file is a complete project-level configuration tailored for a specific full-stack combination:

• nextjs-supabase-stripe -- Next.js 15 + Supabase + Stripe + Tailwind CSS v4
• nextjs-prisma-stripe -- Next.js 15 + Prisma + Stripe + Tailwind CSS v4
• react-express-mongodb -- React + Express + MongoDB + CSS Modules
• vue-nuxt-django -- Vue 3 + Nuxt 3 + Django + Tailwind CSS v4
• fastapi-react-postgres -- FastAPI + React + PostgreSQL + SQLAlchemy

The master file defines your project architecture, directory structure, naming conventions, import style, error handling pattern, and global anti-patterns. Pair it with the technology-specific .mdc rules for deep framework coverage.

Before vs After

Before (No Rules)

• Pages Router code when you need App Router
• Default exports when you use named exports
• Inline styles when you use Tailwind
• No loading or error states
• Missing TypeScript types
• fetch without error handling
• Deprecated tailwind.config.js syntax
• 20+ minutes fixing each response

After (With Mega Pack)

• Correct App Router Server Components
• Named exports with proper types
• Tailwind CSS v4 utility classes
• Loading and error boundary files
• Full TypeScript strict mode compliance
• Type-safe data fetching with error handling
• CSS-first Tailwind v4 configuration
• 0 minutes fixing -- correct on first try

Who Is This For

• Developers using Cursor for any stack who are tired of the AI generating generic, outdated, or incorrect code that requires constant manual corrections.
• Full-stack developers working across multiple projects who need a reusable set of rules they can drop into any new project regardless of the tech stack.
• Teams (2-10 developers) who need a shared standard for how Cursor writes code in their codebase, so every team member's AI output is consistent.
• Developers adopting new frameworks who want Cursor to generate idiomatic code for a framework they are still learning (e.g., switching from Express to FastAPI, or from React to Vue).
• Freelancers and agencies who build projects for clients across different stacks and want production-quality AI output from day one on every engagement.

What You Get

• 30 technology-specific .mdc rule files -- Covering frameworks, databases, payments, styling, testing, languages, and DevOps.
• 5 master .cursorrules files -- Pre-built project-level configurations for the most common full-stack combinations.
• Quick Start Guide -- Get from download to working configuration in under 5 minutes.
• Customization Guide -- Learn how to modify rules, create your own, and combine rules across categories.
• Lifetime updates -- When frameworks release new versions, the rules are updated. You receive every update at no additional cost.

What Makes This Different

vs. Free .cursorrules from GitHub

• Specificity -- Free: Generic, one-size-fits-all / Mega Pack: Deep coverage per framework with version-specific rules
• Code examples -- Free: Minimal or none / Mega Pack: Concrete "do this / not that" for every pattern
• Anti-patterns -- Free: Rarely covered / Mega Pack: Explicit rules for common AI mistakes per framework
• Integration -- Free: Individual files, untested together / Mega Pack: 35 files designed to work together without conflicts
• Stack coverage -- Free: Usually 1 framework / Mega Pack: 10 frameworks, 5 databases, 4 test tools, and more
• Updates -- Free: Sporadic, if ever / Mega Pack: Lifetime updates with every major version
• Documentation -- Free: README at best / Mega Pack: Quick Start + Customization guides

vs. Writing Your Own Rules

You absolutely can write your own rules, and many developers do. The difference is time. This pack represents hundreds of hours of iteration: testing which phrasings actually change AI behavior, discovering which anti-patterns the AI needs to be explicitly told to avoid, and structuring rules so they work together as a system rather than conflicting with each other. You could build this yourself, but it would take weeks of experimentation to reach the same level of effectiveness.

Frequently Asked Questions

Do I need all 30 rules?

No. Install only the rules that match your stack. A typical project uses 5-8 rules. The pack gives you coverage for multiple stacks so you can reuse it across all your projects.

Does this work with Windsurf or other AI IDEs?

The .cursorrules and .mdc file formats are supported by several AI IDEs. Windsurf can read .cursorrules files. However, the pack is tested and optimized specifically for Cursor.

Will this work with my existing project?

Yes. The configuration files are purely additive -- copy them into your project and they take effect immediately. No code changes required. No dependencies to install. No build step.

I already have a .cursorrules file. Will this conflict?

The pack's master file replaces your existing one. The Customization Guide walks you through merging your existing rules with the pack's rules so you keep your custom conventions while gaining the pack's framework-specific depth.

How is this different from AI Dev Config Kit?

The AI Dev Config Kit is a deep, single-stack product focused on Next.js 15 + Supabase + Stripe, and includes both Cursor and Claude Code configurations. The Cursor Rules Mega Pack is a broad, multi-stack product focused exclusively on Cursor with coverage across 10+ frameworks. Choose the Mega Pack if you work with multiple stacks or do not use Claude Code.

Do I get updates?

Yes, free lifetime updates. When frameworks release new major versions, the rules are updated accordingly. Updates are delivered through Gumroad at no additional cost.

What if it does not work for me?

30-day money-back guarantee, no questions asked. If the pack does not improve your Cursor workflow, request a full refund through Gumroad within 30 days. You will receive your money back promptly.

Can I use this for client projects?

Yes. The license permits use in unlimited personal and commercial projects, including client work and freelance engagements. A single license covers up to 10 developers on the same team. The only restriction is that you cannot redistribute or resell the rule pack itself.

Can I share individual rules with my team?

Yes. Individual rule snippets and excerpts can be shared with attribution. You may not share the complete pack as a standalone product.

What Developers Are Saying

"I was copy-pasting the same .cursorrules corrections into every project. Now I just drop in the right master file and the relevant .mdc rules, and Cursor gets it right the first time. Across three different stacks."

"The anti-pattern sections are worth the price alone. I did not realize how many bad patterns Cursor was generating until I saw the rules explicitly block them."

"I tried free rules from GitHub for my FastAPI project. They were so generic they barely helped. The Mega Pack's FastAPI rule covers Pydantic v2, async dependencies, proper error responses -- all the stuff I was manually fixing every time."

30-Day Money-Back Guarantee

Try the Cursor Rules Mega Pack in your projects. If it does not noticeably improve the quality and consistency of your AI-generated code, request a full refund through Gumroad within 30 days. No questions asked. The risk is entirely on us.

Lifetime Updates

Buy once. Benefit forever. When frameworks release new versions, the rules are updated to reflect the latest APIs and patterns. Every update is delivered through Gumroad at no additional cost. Your $19 investment today keeps paying dividends for years.
