HTTP / HTTPS traffic interceptor and debugger for Windows

HTTS Debugger is a local proxy tool that captures, inspects, and manipulates HTTP and HTTPS traffic in real time. It sits between your browser and the internet, giving you full visibility into every request and response — including encrypted HTTPS connections.

Built with .NET Framework 4.8 and WPF, it runs as a lightweight desktop application with a terminal-inspired dark interface.

• HTTPS Decryption — built-in Certificate Authority generates trusted certificates on the fly, allowing transparent inspection of encrypted traffic.
• Live Traffic Capture — all HTTP and HTTPS requests passing through the proxy are logged with timing, status codes, headers, cookies, and body content.
• Request & Response Inspection — view headers, content, raw data, and cookies for both sides of every transaction. Compressed responses (gzip, deflate) are automatically decompressed.
• Filtering — narrow down captured sessions by domain, HTTP method, status code, or free-text search.
• Edit & Resubmit — modify any captured request and send it again to test different payloads or parameters.
• Manual Submitter — craft HTTP requests from scratch and fire them directly through the proxy.
• Export — save captured traffic to text files for offline analysis or sharing.
• CA Management — export the root certificate to disk or install it directly into the Windows trusted store with one click.

1. Launch HTTSDebugger.exe.
2. Click Start to begin capturing on 127.0.0.1:8888 (port is configurable in the toolbar).
3. Configure your browser or system to use 127.0.0.1:8888 as the HTTP/HTTPS proxy.
4. To inspect HTTPS traffic, click Install CA or Export CA and trust the generated root certificate.
5. Browse normally — all traffic will appear in the session list.

• Windows 7 or later
• .NET Framework 4.8
