Desynq is an automated, measurement-driven DPI bypass and transparent DNS interceptor for Windows, powered by the Zapret (winws2) engine and WinDivert.
Instead of manually guessing complex Zapret command-line arguments (--lua-desync, --split-pos, --dpi-desync), Desynq automatically probes what your ISP actually blocks, tests 68 desynchronization techniques against your targets, ranks them by real handshake latency, and deploys the winning strategy as a background Windows Service.
- Automated Zapret Strategy Discovery: Tests 68 desynchronization candidates (multisplit, multidisorder, fakesplit, seqovl, fake) and selects the lowest-latency working method for your ISP.
- Zero-Wait Instant Profiles: Pre-configured 0s profiles for Turkcell Mobile, Vodafone Mobile, and TurkNet.
- Transparent DoH Interceptor: Kernel-level WinDivert engine intercepts outbound UDP port 53 and tunnels queries through encrypted Cloudflare DoH with a 0ms in-memory RAM cache.
- QUIC / HTTP/3 Downgrade: Silently drops UDP 443 to force browsers to fallback to TCP TLS, neutralizing UDP-based SNI blocking.
- True "Install & Forget" Windows Service: Runs as a native background service (
desynq-dpi&desynq-dns). Automatically protects your entire PC on boot with zero GUI or tray window needed. - Pure Desktop GUI: Modern, frameless, lightweight desktop UI with zero console flash (
-H windowsgui). - Bilingual Interface: Auto-detects system language (Turkish & English) with in-app switching.
