The Problem

Testing how your app handles 500 errors, timeouts, or 429 rate limits requires mocking. Setting up mock servers takes time. No simple API returns any status code on demand. Testing edge cases like 503 or 429 is hard without controlled endpoints. Monitoring tools need test endpoints for alert verification.

The Solution

Simple API that returns any HTTP status code you request — with configurable response body, headers, and delay — perfect for testing error handling, retry logic, and monitoring alerts.

Target Audience

Developers testing API error handling, QA engineers verifying error states in applications, and DevOps teams testing monitoring alert configurations

Key Features

1
GET/POST to /status/{code} returns that HTTP status code
2
Configurable response delay for testing timeout handling
3
Custom response body and headers via query parameters
4
Random failure mode: succeed 80% of the time, fail 20%
5
Rate limit simulation with proper 429 headers and Retry-After
6

Why Now?

API-first development needs testing tools. CI/CD requires automated testing. Error handling is often untested. Simple developer tools have viral adoption. Free tier drives awareness for premium features.

Revenue Model

Free: unlimited requests. Pro: $3/mo (custom responses + delay + no rate limit). Annual: 20% discount.

Competitive Landscape

httpstat.us

HTTP status API. Free, basic, limited customization

httpbin.org

HTTP testing. Free, broad scope, not status-code focused

Local mock server

Setup time, not shareable, not CI/CD friendly

Postman mock

Part of Postman. Complex setup, overkill for simple status testing
