rate limiting
made easy

Protect your serverless/edge APIs from abuse. Start rate-limiting expensive requests with a simple API today.

👉 👈
Control the number of :max requests made within a specified :interval, e.g. for each user :key
// GET /:namespace/:max/:interval/:key
=> 200 OK <=
{ok: true, remaining: 3}

🧑‍💻 Examples 🧑‍💻

configure, copy-paste, start limiting, all within minutes

const namespace = "example" // rlimit.com namespace ID
2
const key = "user:123" // identifier - user/account ID, IP, operation, etc
3


4
// limit $key to 10 requests every 30s
5
const limit = await fetch(`https://rlimit.com/${namespace}/10/30s/${key}`)

// or limit.status === 429 
8
if (!limit.ok) {

  // rate limited

  // for example, reject request
