عبور

Ubour (عبور) is a high-performance, open-source censorship circumvention and network privacy suite engineered for Android and Windows PC.

Unlike conventional VPN services that route all your internet traffic through external third-party proxy servers (introducing latency, bandwidth caps, and privacy risks), Ubour operates directly on your device:

Censorship Circumvention: Manipulates and segments TCP/TLS packets and HTTP headers at the socket/kernel level to evade Deep Packet Inspection (DPI) censorship systems deployed by Internet Service Providers (ISPs). Built-in Local Ad & Tracker Blocker: Integrates over 180,000+ full rule lists from uBlock Origin and AdGuard, filtering unwanted advertisements and telemetry locally before they leave your device. Independent DNS & Privacy: Pure direct connection with neutral DNS resolvers (Google DNS 8.8.8.8, Quad9 9.9.9.9, AdGuard DNS 94.140.14.14) without forcing intermediary proxies. Isolated Cloudflare WARP & VLESS Reality Support: Optional dedicated tunnels for specialized censorship environments when explicitly chosen. Native Full Speeds: Zero server overhead ensures 100% of your native ISP bandwidth and minimal latency.
