• Traffic interception. Fluxzy Desktop lets you capture all HTTP/HTTPS traffic generated by applications on the system. It uses a built-in proxy mechanism to redirect requests and responses, recording each exchange accurately. The tool decrypts SSL/TLS-encrypted traffic without affecting data integrity.
• Content inspection. Every HTTP/HTTPS request and response can be examined in detail. The interface displays headers, message bodies, cookies and metadata. Data is organized hierarchically to simplify navigation and the analysis of complex structures.
• Real-time modification. Allows you to alter HTTP/HTTPS requests and responses before they are sent or received. This feature is essential for testing application behavior under different conditions without modifying the source code.
• Advanced filtering. The tool includes a filtering system based on criteria such as URL, HTTP methods, status codes and content. Filters can be combined to isolate specific traffic and reduce noise when analyzing large volumes of data.
• Data export. Supports multiple export formats, including HAR (HTTP Archive), JSON and CSV. Records can later be processed in other tools or shared for team collaboration.
• Performance analysis. Measures response times, latency and throughput for each HTTP transaction. Data is presented in charts and tables that help identify bottlenecks and optimize application performance.
• REST API support. Fluxzy Desktop can work with RESTful APIs, displaying request and response structures in a readable format. Includes syntax highlighting for JSON and XML.
• Built-in authentication. Supports various authentication mechanisms, including OAuth, Basic Auth and client certificates. This lets you test authorization flows without additional configuration.
• Custom rules. Lets you define rules to automate actions such as replacing headers, redirecting requests or injecting payloads. Rules are applied dynamically during traffic capture.
• WebSocket compatibility. Captures and analyzes WebSocket traffic, showing bidirectional messages in real time. The tool reconstructs message sequences to make debugging easier.
• HTTP/2 and HTTP/3 support. Fluxzy Desktop is compatible with modern versions of the HTTP protocol, including features such as multiplexing and server push.
• Development environment integration. Can be used alongside popular IDEs and command-line tools. Proxy configuration is managed automatically to simplify the workflow.

Fluxzy Desktop was developed by a team specializing in network and security tools. The project began as a solution for specific HTTP debugging needs in corporate environments. The application has evolved through regular updates that add support for new protocols and advanced analysis features.
