😴 httsleep

A simple service for producing delayed HTTP responses. Perfect for testing how your applications handle slow network requests, timeouts, and loading states.

Why httsleep?

• Test how your UI handles slow API responses (loading spinners, skeleton screens)
• Verify timeout behavior in HTTP client libraries
• Simulate network latency that Chrome DevTools throttling can't replicate
• Test async scenarios where requests take longer than your normal environment

Features

⏱️ Simple Delay

Returns a 200 OK response after waiting the specified number of seconds.

Pattern: /:seconds

Examples:

https://httsleep.r10r.dev/3      # Wait 3 seconds
https://httsleep.r10r.dev/0.5    # Wait 500ms
https://httsleep.r10r.dev/10     # Wait 10 seconds

Usage:

// Test a 5-second timeout
fetch("https://httsleep.r10r.dev/5")
  .then((response) => console.log("Response received after 5 seconds"))
  .catch((error) => console.log("Request failed or timed out"));

↪️ Delayed Redirect

Redirects to the specified URL after waiting. Returns a 301 redirect response.

Pattern: /:seconds?redirectUrl=:url

Examples:

https://httsleep.r10r.dev/3?redirectUrl=https://httpbin.org/headers
https://httsleep.r10r.dev/2?redirectUrl=https://example.com

Usage:

// Test redirect handling with network latency
fetch("https://httsleep.r10r.dev/2?redirectUrl=https://api.example.com/data", {
  redirect: "follow",
})
  .then((response) => response.json())
  .then((data) => console.log(data));

🔀 Delayed Proxy

Fetches a URL and returns its response after the delay. The original response headers and status code are preserved.

Pattern: /:seconds?proxyUrl=:url

Examples:

https://httsleep.r10r.dev/3?proxyUrl=https://httpbin.org/json
https://httsleep.r10r.dev/5?proxyUrl=https://api.github.com/users/octocat

Usage:

// Simulate a slow API response with real data
fetch(
  "https://httsleep.r10r.dev/3?proxyUrl=https://jsonplaceholder.typicode.com/posts/1"
)
  .then((response) => response.json())
  .then((data) => console.log("Received after 3 seconds:", data));
