Best .cursorrules Templates for 2026

The .cursorrules file is one of the most powerful yet underused features in Cursor. A well-written rules file transforms Cursor from a generic autocomplete tool into a context-aware coding partner that understands your stack, your conventions, and your project architecture from the first keystroke.

This guide provides a curated collection of the best .cursorrules templates for 2026. Every template is free, ready to copy, and battle-tested by Indian developers building real production applications.

What Are .cursorrules?

The .cursorrules file sits at the root of your project directory. Cursor reads it automatically every time you open the project, injecting its contents into every Composer and Chat interaction. Think of it as a standing set of instructions you give to your AI coding assistant.

Without .cursorrules, you find yourself repeating the same context: "I am using Next.js 15 with App Router, not Pages Router." "Use Tailwind, not CSS modules." "My database is PostgreSQL with Prisma." With a good rules file, Cursor knows all of this upfront.

The file supports plain text or markdown formatting. Most developers structure it with clear sections covering the tech stack, project structure, coding conventions, and explicit prohibitions.

Top 10 .cursorrules Templates for 2026

1. React + TypeScript

# React + TypeScript Project
- React 19 with functional components only
- TypeScript strict mode — no `any` types ever
- Props: explicit interfaces, named exports only
- State: prefer useReducer for complex state, useState for simple
- Effects: minimal useEffect — prefer Server Components or event handlers

- Testing: Vitest + React Testing Library
- DO NOT use class components, default exports, or inline styles

2. Next.js 15 (App Router)

# Next.js 15 App Router Project
- Server Components by default — 'use client' only when absolutely needed

- DO NOT use Pages Router patterns, getServerSideProps, or CSS modules

3. Python (FastAPI)

# Python FastAPI Project
- Python 3.12+, FastAPI 0.115+
- Type hints on ALL functions — no bare def signatures
- Async everywhere — all route handlers must be async def
- Pydantic v2 for validation, SQLAlchemy 2.0 for ORM
- Use | for union types (not Union[])
- Error handling: HTTPException with proper status codes
- Logging: use logging module, never print()
- DO NOT put business logic in route handlers — use service layer

4. TypeScript (Node.js Backend)

# Node.js TypeScript Backend
- TypeScript 5 strict mode, ESM modules
- Express 5 or Fastify 5 for HTTP
- Zod for runtime validation
- Prisma or Drizzle for database access

- Error handling: custom error classes extending Error
- Environment: dotenv for config, never hardcode secrets
- DO NOT use require(), CommonJS, or any type

5. Go

# Go Project
- Go 1.23+, standard library preferred over third-party
- Error handling: always check errors, wrap with fmt.Errorf
- Naming: exported = PascalCase, unexported = camelCase
- Concurrency: use context.Context for cancellation, sync.WaitGroup for coordination
- Testing: table-driven tests in _test.go files
- Structure: cmd/ for entrypoints, internal/ for private packages, pkg/ for public
- DO NOT use init(), global variables, or panic for error handling

6. Rust

# Rust Project
- Rust 2024 edition, stable toolchain
- Error handling: use thiserror for libraries, anyhow for applications
- Prefer &str over String for function parameters
- Use iterators and combinators over manual loops
- Clippy: treat all warnings as errors
- Async: tokio runtime for async code
- DO NOT use unwrap() in production code — use ? operator or expect() with context

7. Java (Spring Boot)

# Java Spring Boot Project
- Java 21, Spring Boot 3.4+
- Constructor injection only — no field injection with @Autowired
- Records for DTOs, sealed interfaces for enums
- Lombok: @Builder and @Slf4j only — avoid @Data
- Jakarta Validation for request validation
- JPA: entity per table, repository per entity
- DO NOT use .get() on Optional without isPresent check

8. Flutter (Dart)

# Flutter Project
- Flutter 3.27+, Dart 3.6+
- State management: Riverpod 2.0 (not Provider or BLoC)
- Folder structure: features/ with sub-folders for each feature
- Widgets: small, composable, prefer const constructors
- Navigation: go_router for declarative routing
- API calls: dio with interceptors for auth tokens
- DO NOT use setState in complex widgets — use Riverpod providers

9. Tailwind CSS

# Tailwind CSS Rules
- Tailwind CSS 4 with @theme configuration
- Mobile-first responsive: base styles then sm:, md:, lg:
- Dark mode: class strategy with dark: prefix
- Custom colors: define in @theme, reference by name
- Components: extract with @apply only for highly reused patterns
- Spacing: use Tailwind scale (p-4, m-2), avoid arbitrary values
- DO NOT use inline styles, CSS modules, or styled-components alongside Tailwind

10. Testing (Playwright + Vitest)

# Testing Rules
- E2E: Playwright with page object model pattern
- Unit: Vitest with describe/it blocks
- Naming: test descriptions should read like sentences
- Assertions: specific matchers (toHaveText, not toBeTruthy)
- Data: use factories for test data, never hardcode
- Selectors: data-testid attributes for E2E, avoid CSS selectors
- DO NOT test implementation details — test user-visible behavior

How to Create Custom .cursorrules

Creating your own .cursorrules is straightforward:

1. Create the file in your project root: touch .cursorrules
2. Start with your stack — list exact versions of frameworks and tools
3. Define your architecture — describe the folder structure and where things live
4. Add conventions — naming, patterns, what you prefer and what you prohibit
5. Include examples — show one correctly structured component or function
6. Commit to your repo — your entire team benefits from shared rules

Review your rules monthly. Every time you correct Cursor more than twice for the same mistake, add a rule for it. Keep the file under 500 lines for best performance.

.cursorrules vs Global Rules

| Aspect | .cursorrules | Global Rules | |--------|-------------|--------------| | Scope | One project only | All projects | | Location | Project root directory | Cursor Settings | | Shared with team | Yes (committed to repo) | No (local only) | | Override priority | Higher (wins on conflict) | Lower | | Best for | Stack, architecture, team conventions | Personal style preferences |

Use global rules for things like "always use TypeScript" or "prefer functional patterns." Use .cursorrules for project-specific details like your folder structure, database schema patterns, and domain-specific business logic.

India-Specific Tips

Cursor Pricing in India (March 2026):

• Free tier: Limited completions, Cursor Tab, 2-week Pro trial
• Pro: $20/month (~₹1,650/month) — 500 fast requests, unlimited slow
• Business: $40/month (~₹3,300/month) — admin controls, SSO
• Student discount: Free Pro for 1 year with .edu or .ac.in email

For Indian developers on a budget, the free tier combined with well-written .cursorrules gives you excellent results. Good rules reduce wasted completions because Cursor gets things right the first time.

Add India-specific rules to your .cursorrules:

## India-Specific
- Currency: display as ₹1,00,000 (Indian lakhs/crores format)
- Phone validation: +91 prefix, 10-digit number
- Date format: DD/MM/YYYY (Indian standard)
- GST calculations: always server-side, never expose rates in frontend
