Intercept, inspect, and debug HTTP(S) traffic for Windows API development

Visit Website

Overview

HTTP Toolkit is a essential tool for Windows API developers, enabling interception and analysis of HTTP/HTTPS traffic from any app—browsers, desktop tools, CLI, and more. It integrates with Windows' network stack for easy setup, supports TLS decryption via local root certificates, and offers a clean interface to inspect headers, payloads, response times, and WebSocket messages. You can mock responses, throttle connections, and export data for debugging. Works seamlessly with Windows 10/11, integrates with VS Code, and has free/pro tiers for basic or advanced use cases.

Key Features

  • Intercept HTTP(S) traffic from any Windows application
  • Mock API responses and throttle network connections
  • Inspect detailed request/response data (headers, payloads, TLS) and WebSockets

Frequently Asked Questions

? Is HTTP Toolkit compatible with Windows 11?

Yes, HTTP Toolkit fully supports Windows 11, as well as Windows 10. It leverages Windows' network capabilities to intercept traffic from all apps without compatibility issues.

? Is it safe to install?

Absolutely. HTTP Toolkit generates a local root certificate for TLS decryption (never shared externally), and its core is open-source. It does not collect or share your traffic data with third parties.

? Is there a portable version?

Currently, HTTP Toolkit does not offer an official portable version for Windows. The installer is required to set up necessary components for traffic interception and OS integration.
