# Daily Comparison #31: Algorithms for Rate Limiting - Choosing the Right Strategy
Welcome back to Daily Comparison! Today, we're diving into a critical component of building resilient and secure web services: **rate limiting**. Rate limiting is the process of controlling the number of requests a client can make to a server within a given time window. It protects APIs from abuse, DDoS attacks, and ensures fair resource distribution. We'll explore and compare five of the most common algorithms used to implement this.
