GoThrottle is a config-driven reverse proxy that enables distributed rate-limiting with support for global, per-route, and per-IP throttling. It allows developers to enforce traffic limits and dynamic routing without changing application code, entirely through a declarative config.yaml.

---

Project Overview

GoThrottle is a modular reverse proxy written in Go, designed for scalability and observability. It uses a token-bucket algorithm for request throttling and supports pluggable storage backends like Redis or in-memory stores.

Developers can define routing rules, throttle limits, upstream services, and middleware pipelines directly from configuration — making it suitable for distributed, multi-service architectures.

Key Features

• Token-Bucket Rate Limiting
  Supports global, per-route, and per-IP throttles configurable via YAML.

• Declarative Routing Layer
  Define upstream services, paths, and limits without modifying code.

• Pluggable Backend Stores
  Built-in support for Redis and in-memory rate limit counters.

• Middleware Pipeline
  Request logging, structured JSON output, panic-safe recovery, and more.

• Production-Grade Config System
  Full control using a single config.yaml file.

Why This Project Matters

GoThrottle demonstrates backend systems engineering, traffic control, and high-performance Go design. It highlights practical experience in:

• Building reverse proxies
• Designing middleware pipelines
• Implementing scalable rate-limiting mechanisms
• Managing distributed state with Redis
• Declarative, config-first backend systems

This project reflects the ability to design production-ready infrastructure components, essential in API gateways, platform engineering, and SaaS multi-tenant architectures.
