They allow you to ensure that one or more bad actors can’t accidentally or deliberately overload the service. Nov 4, 2025 · Rate limiting is an essential technique in web applications to control the number of requests clients can make within a defined period. Mar 16, 2023 · Here is a basic design for a rate limiter API In this article, we will discuss the design of a rate limiter API, including its requirements, high-level design, and algorithms used for rate limiting. Once the upper limit is reached, the rate limiter blocks further requests. It restricts the number of API calls a client can make within a specified time period, preventing any single user from overwhelming the system. Explore algorithms, distributed enforcement, caching, data structures, API gateways, scalability, and interview-ready architecture fundamentals. Rate limiters are a key part of building an API or large scale distributed system, they help when we wish to throttle traffic based on the user. We’ll answer fundamental questions such as why we need a rate limiter and how we can design and implement it. By understanding its architecture, scaling mechanisms, and implementation strategies, developers can design robust systems that handle diverse usage patterns effectively. g. Let’s start by answering the very first question: A rate limiter restricts the number of events that a certain user or device can perform within a given time range.
