HTTP Toolkit Tim Perry

HTTP Toolkit is a versatile open-source tool designed to simplify debugging, testing, and working with HTTP(S) across Windows, Linux, and macOS. It empowers developers and teams to capture, inspect, modify, and send HTTP traffic efficiently.

Key Features:

• Advanced Inspection: Analyze requests and responses with content-type highlighting, parameter parsing, header documentation, and built-in support for JSON, XML, HTML, and more.
• Breakpoints & Manual Editing: Pause in-flight HTTP traffic to modify requests, headers, status codes, or bodies in real-time.
• Custom Request Sending: Test APIs or explore endpoints with a fully featured client that handles all aspects of HTTP communication.
• Automated Rewrite Rules: Inject mock responses, redirect traffic, transform messages, and simulate server behaviors for robust testing.
