About HTTP Status Lab
HTTP Status Lab is a visual cheat sheet designed to help developers, testers, and students understand HTTP status codes with practical API examples.
Our Mission
Our goal is to make HTTP status codes easier to learn, remember, and apply in real API development and API testing scenarios. Instead of showing only a static list of codes, HTTP Status Lab explains each status code with meaning, common API scenarios, tester notes, developer notes, and interview-friendly explanations.
Who This Is For
Built for everyone who works with APIs.

QA Engineers & SDETs

Students
Learning web development, APIs, and HTTP fundamentals with clear examples.
Interview Candidates

What Makes HTTP Status Lab Different
Most HTTP status code pages are static. We focus on practical, visual learning.
Created for the developer and testing community
HTTP Status Lab was created as a learning-first tool for anyone who works with APIs. The site is especially useful for developers, testers, students, and professionals preparing for technical interviews.
Created by Rohit Dhepe, a QA/SDET professional with experience in mobile automation, API testing, and test automation frameworks.
Disclaimer
HTTP Status Lab is an educational and reference website. While we aim to keep the information accurate and useful, always refer to official HTTP specifications and your organization’s API standards when making implementation decisions.
