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