Rate Limiter Generator

Describe your rate limiting needs. Get production-ready config for express-rate-limit, Redis-backed limiters, or custom implementations. Protect your API without reading documentation.

One command. Zero config. Just works.

Quick Start

npx ai-rate-limit "100 requests per minute per user"

What It Does

Generates rate limiting middleware and configuration
Supports in-memory, Redis, and database-backed stores
Creates tiered limits for different user types
Handles API key and IP-based limiting
Includes proper rate limit headers in responses

Usage Examples

# Simple IP-based limiting
npx ai-rate-limit "60 requests per minute per IP"

# User tier-based limits
npx ai-rate-limit "free users 100/hour, pro users 1000/hour"

# Redis-backed for distributed systems
npx ai-rate-limit "500 requests per minute" --store redis

# Endpoint-specific limits
npx ai-rate-limit "10 login attempts per 15 minutes"

# With sliding window
npx ai-rate-limit "1000/day sliding window" --algorithm sliding

Best Practices

Start generous, tighten later - Don't frustrate real users while blocking abuse
Different limits for different endpoints - Login pages need stricter limits than read endpoints
Return proper headers - X-RateLimit-Remaining helps clients behave
Use Redis in production - In-memory limits don't work across multiple servers

When to Use This

Launching an API and need basic protection
Getting hit by scrapers or brute force attempts
Implementing tiered pricing with usage limits
Adding rate limits to specific expensive operations

Requirements

No install needed. Just run with npx. Node.js 18+ recommended.

npx ai-rate-limit --help

How It Works

The tool parses your rate limit description to extract limits, windows, and key strategies. It generates appropriate middleware configuration and optionally the backing store setup for your chosen storage method.
