Rate Limiting by Cloudflare

What it does

Protect your APIs from abuse and your origin from being overwhelmed. Edge-based rate limiting with flexible rules and cost-effective pricing.

Our rate limiting happens at Cloudflare's edge, across 335+ cities. We can block excessive traffic before it ever touches your origin server, saving you bandwidth and compute resources. Define limits based on a wide range of characteristics beyond just IP address, such as specific HTTP headers, query parameters, or even the result of a WAF check. Simple, predictable pricing that is often far lower than a DIY solution, especially when factoring in your saved origin costs. Rate Limiting protects your applications and APIs from abuse, downtime, and cost overruns caused by excessive request rates from malicious bots or misbehaving clients. It gives you precise control over your application's…from cloudflare.com

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
