    UDP OpenVPN/WebSocket + CDN

    Value Added OpenVPN over WebSocket via CDN Tunnel

    UDP Over SSL Tunnel UDP Over SSL Tunnel is a free SSL tool with SNI Host (Spoof Host) support ( SSL Injector ). # OpenVPN-over-WebSocket-CDN **Bypass ISP throttling and DPI by tunneling OpenVPN UDP traffic over WebSocket with Host Header spoofing through major CDN networks (CloudFront / Cloudflare / Akamai).** --- ## What It Does Many ISPs throttle or block VPN traffic using Deep Packet Inspection (DPI). OpenVPN-over-WebSocket-CDN wraps OpenVPN UDP inside a WebSocket connection with a spoofed `Host` header, routing traffic through major CDN edge networks (CloudFront, Cloudflare, or Akamai). To any firewall or DPI system, the traffic looks like a legitimate WebSocket upgrade to a CDN-hosted domain.

    UDP OpenVPN Server tls SNI VPS

    UDP OpenVPN Server tls SNI VPS

    Value Added OpenVPN over SNI via SNI injection SSL/TLS Tunnel

    How It Works [Android Device] │ │ OpenVPN TCP/UDP ▼ [SNI Tunnel Client] ← Wraps traffic in SSL + injects fake SNI │ │ Looks like: HTTPS → microsoft.com ✓ ▼ [ISP Firewall] ← Passes through — sees only valid HTTPS │ ▼ [VPS Server] ← Decrypts TLS, recovers OpenVPN traffic │ ▼ [OpenVPN Server] ← Receives native OpenVPN traffic │ ▼ Internet The core trick is SNI injection: the tunnel client inserts a trusted domain name (e.g. microsoft.com) into the TLS handshake. The ISP sees what appears to be a standard HTTPS connection and allows it through. The VPS server on the other end strips the SSL wrapper and forwards the real OpenVPN packets to the OpenVPN server.

    Lottie

    Lottie

    Render After Effects animations natively on Mobile, Web & React Native

    Lottie is a wonderful library for Android, iOS, Web, and Windows that works by parsing Adobe After Effects animations that have been exported as json with Bodymovin, and then rendering these natively on mobile and on the web! Now you can have beautiful animations without engineers having to recreate everything by hand. Building animations by hand is time consuming, and other animation alternatives like Gifs and Png sequences don’t offer the same flexibility and varied features that Lottie offers. With Lottie, you can achieve exquisite animations exactly how you want, with no additional engineering effort whatsoever. Take a look at the many beautiful animation possibilities available to you on http://airbnb.io/lottie/
