httpbin
A simple HTTP Request & Response Service.
Overview
httpbin is a web service that provides endpoints that return information about HTTP requests. It's not a traditional mocking tool where you define custom responses, but it is invaluable for testing HTTP clients and libraries by providing predictable responses for various scenarios (e.g., different status codes, headers, redirects).
✨ Key Features
- Endpoints for testing various HTTP verbs (GET, POST, PUT, etc.)
- Returns request headers, body, and origin IP
- Endpoints for testing different response codes and formats
- Can be self-hosted
🎯 Key Differentiators
- Provides a wide range of predefined endpoints for testing HTTP behavior
- Simple, well-documented, and easy to use
- Open-source and easily self-hostable
Unique Value: Provides a free, simple, and reliable way to test how HTTP clients handle various request and response scenarios.
🎯 Use Cases (4)
✅ Best For
- Unit testing an HTTP client's ability to handle redirects
- Verifying that correct headers are being sent in a request
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Mocking APIs with custom business logic or response bodies
- Frontend development against a simulated API
🏆 Alternatives
Not a true mocking tool, but serves as a perfect, predictable endpoint for testing client behavior, a task for which full mocking tools can be overkill.
