A Python CLI tool that detects and classifies Deep Packet Inspection (DPI) based internet censorship, including TCP 16-20KB connection drops, TLS/SNI blocking, HTTP blocking, and DNS hijacking by ISPs. It helps users diagnose which censorship filters their provider applies to specific domains, hostings, and CDNs.

Use cases

• detect if my ISP blocks websites via DPI
• check why connections to CDNs drop after 16-20KB
• test whether DNS queries are being hijacked or spoofed
• find working SNI values for a hosting or CDN
• check if TLS 1.2, TLS 1.3, or HTTP access to a blocked site works
• diagnose internet censorship on my connection
• verify if my DPI bypass tool like zapret is working correctly

When to choose

• you need to identify which censorship mechanisms (TCP RST, SNI blocking, DNS spoofing, TLS MITM) your ISP uses
• you want to test specific domains or CDN/hosting availability from your network
• you need to pick working SNI values for bypass configurations
• you want a customizable, scriptable censorship diagnostic tool

When to avoid

• you need a censorship bypass tool rather than a detector (use zapret or GoodbyeDPI instead)
• you need censorship testing outside networks with DPI-based filtering
• you want a GUI-based testing solution
• you have active bypass tools running that would distort results
