About Cursor Rules Generator

Cursor Rules Generator is a free, open-source tool that helps developers create customized .cursorrulesfiles for Cursor IDE. Our interactive wizard lets you select your tech stack, set coding style preferences, and generate production-ready AI rules in seconds. Whether you are a solo developer working on a side project or part of a large engineering team maintaining multiple codebases, our generator gives you consistent, high-quality rules that make Cursor's AI assistant work exactly the way you want.

Since our launch, thousands of developers have used Cursor Rules Generator to create .cursorrules files for projects ranging from small React components to enterprise Go microservices. The tool runs entirely in your browser — no accounts, no server-side processing, and no data collection — so you can generate rules instantly, privately, and as many times as you need.

Why Cursor Rules Matter

Modern AI coding assistants are powerful but generic by default. Without explicit guidance, they produce code in a one-size-fits-all style that rarely matches your project's conventions. Variables get named inconsistently, imports are added in random order, and architectural decisions deviate from your team's established patterns. Reviewing AI-generated code often takes longer than writing it from scratch — defeating the purpose of using AI assistance in the first place.

A .cursorrulesfile solves this by giving Cursor IDE a permanent set of instructions that it consults on every interaction. Think of it as your project's constitution: a single source of truth for how code should be written, structured, and tested. Once you define your rules, every AI-generated line respects them automatically. The time you invest upfront in crafting good rules pays back exponentially through faster code reviews, fewer style nitpicks in PRs, and more consistent codebases that new team members can navigate intuitively.

The challenge has always been that writing a comprehensive.cursorrules file from scratch is tedious and error-prone. Covering every framework, every naming convention, and every edge case takes hours of research and debugging. That is exactly why we built Cursor Rules Generator — to turn hours of manual configuration into a 30-second interactive workflow that produces expert-level rules every time.

Our Mission

Cursor IDE's .cursorrulessystem is one of the most powerful features in AI-assisted development, but it is also one of the most underutilized. Most developers either do not use it at all or write minimal rules that fail to capture their team's full conventions. The result is AI-generated code that is inconsistent, hard to review, and requires substantial rework.

We believe every developer — regardless of experience level or team size — deserves first-class AI assistance that respects their unique coding standards. Our mission is to make best-practice .cursorrules configuration accessible, fast, and free for everyone. By providing expertly crafted templates for 26+ tech stacks, we eliminate the guesswork and let you focus on building great software instead of tweaking AI instructions.

We are committed to keeping this tool free forever. There are no premium tiers, no usage limits, and no plans to monetize. If you find Cursor Rules Generator useful, the best way to support us is to share it with your team and contribute template improvements on GitHub.

How the Generator Works

Our generator uses a modular template engine that combines framework-specific best practices with your personal coding preferences. Each of our 26 templates is a carefully researched collection of rules covering code style, naming conventions, architectural patterns, testing requirements, and framework-specific idioms. When you select multiple stacks, the engine intelligently merges the templates, deduplicates overlapping guidance, and applies your chosen style preferences — indentation, quote style, semicolon usage, naming conventions, and AI strictness level.

The merging process is designed to handle real-world complexity. When two templates specify the same rule — for example, both React and TypeScript templates define naming conventions — the engine resolves conflicts using a priority system that favors the more specific framework. If you select React, TypeScript, and Tailwind CSS together, the output file includes a unified code style section derived from all three, a React-specific architectural patterns section, a TypeScript-specific type discipline section, and a Tailwind-specific styling section — all without duplication.

Under the hood, each template is a TypeScript module that exports structured rule objects organized into categories: code style, naming, imports, architecture, testing, documentation, and security. The engine reads your selections, collects the relevant rule objects, normalizes them into a consistent format, resolves conflicts through category-aware merging, and serializes everything into a clean .cursorrules file ready for immediate use.

The entire generation process happens in your browser using client-side JavaScript. No rules data is ever sent to a server or stored externally. You can see a real-time preview of your rules as you configure them, download the final .cursorrules file with a single click, and place it directly into your project's root directory. Cursor IDE picks it up instantly.

Template Quality & Maintenance

Every template in our library goes through a rigorous quality review before being published. We research each framework's official style guides, community conventions, and real-world usage patterns from popular open-source projects. The rules we include are not generic suggestions — they reflect the actual coding standards that experienced developers follow in production. For example, our React template enforces functional components with explicit TypeScript types, our Go template mandates idiomatic error handling and package organization, and our Python template aligns with PEP 8 and modern type annotation practices. We do not simply copy-paste documentation into a rules file; each rule is written in clear, unambiguous language that Cursor IDE interprets consistently.

Maintenance is an ongoing commitment. JavaScript frameworks release major versions with breaking changes, TypeScript introduces new features that shift best practices, and community conventions evolve as new patterns emerge. We monitor framework changelogs, community discussions on GitHub and Reddit, and industry blog posts to keep our templates current. When React 19 introduced Server Components as the default, we updated our React and Next.js templates to include rules for client and server component boundaries. When Go 1.22 changed loop variable semantics, our Go template followed suit. You benefit from this continuous maintenance automatically — simply regenerate your rules whenever you update your project's dependencies, and you will receive rules that reflect the latest ecosystem standards.

Supported Tech Stacks

We currently support 26 tech stacks across frontend, backend, fullstack, mobile, and infrastructure categories. Each template is maintained to reflect current best practices for its framework, and we regularly update them as ecosystems evolve.

26 templates total — select one or combine multiple for full-stack projects.

Open Source & Community

Cursor Rules Generator is fully open source under the MIT license. The complete source code — including the template engine, all 26 framework templates, and the Next.js frontend — is available on GitHub. We welcome contributions of all kinds: new framework templates, improvements to existing rules, bug fixes, documentation enhancements, and feature suggestions.

If you have expertise in a framework that is not yet covered or notice that a template could better reflect current best practices, please open an issue or submit a pull request. Community contributions are what keep our templates accurate and comprehensive. We review contributions promptly and value every submission, whether it is a single rule correction or an entirely new template.

Who Uses Cursor Rules Generator

Our tool serves a diverse range of developers and teams. Solo developers use it to maintain personal coding standards across side projects without spending time manually writing rules for each framework. Startup teams rely on it to establish consistent conventions early, preventing the chaos that happens when five engineers write code in five different styles. Open source maintainers include generated .cursorrules files in their repositories so contributors automatically follow project conventions — reducing the cognitive load of reviewing first-time pull requests.

Enterprise teams benefit from the template engine's ability to combine multiple tech stacks into a single coherent rules file. A team building a React frontend with a Go backend and PostgreSQL database can select all three frameworks and get merged rules that respect each ecosystem's idioms while maintaining consistent cross-cutting conventions like naming and error handling. The result is AI-generated code that looks right whether it hits the frontend, backend, or database layer.

Educators and coding bootcamp instructors use our generator to create standard .cursorrulesfiles that they distribute to students. This ensures that every student's AI assistant enforces the same coding standards taught in class, reinforcing good habits and making assignment grading more consistent.

Getting Started in Under a Minute

Using Cursor Rules Generator is intentionally simple. Start by visiting the generator page, where you will see a clean interface with checkboxes for all 26 tech stacks. Select the frameworks your project uses — you can mix frontend and backend stacks freely. Below the framework selector, choose your coding style preferences: indentation width, quote style, semicolon usage, and naming convention. If you have project-specific requirements, type them into the custom rules text area. The real-time preview updates instantly as you make changes, so you can see exactly what your rules will look like before downloading. Once satisfied, click the download button and save the file to your project root. Cursor IDE detects it on the next interaction — no restart required, no plugins, no accounts, and no payment of any kind.

Privacy & Data

Privacy is a core design principle of Cursor Rules Generator. The entire tool runs client-side in your browser. We do not collect, store, or transmit any of the following: your tech stack selections, your style preferences, your custom rules content, any generated .cursorrules output, your IP address, or any personally identifiable information. There is no backend server processing your rules data at any point in the workflow.

We use Microsoft Clarity and Google Analytics solely to understand aggregate usage patterns — such as which pages are most visited and how users discover the tool. These services do not capture any content you type or generate. No third party has access to your rules data because it never leaves your browser. If you prefer complete isolation, you can clone the repository and run the generator entirely offline.
