📡 Multik Sila — sing-box & Xray VPN Client

Multik Sila is a free and open-source VPN/proxy client for Windows and Android, built with Flutter as a graphical interface for the sing-box and Xray-core networking engines. It supports modern proxy protocols, system-wide TUN routing, split tunnelling and flexible subscription management.

🌐 Proxy & VPN Support

Multik Sila supports:

• VLESS, including REALITY and XHTTP • VMess • Trojan • Hysteria2 • Shadowsocks

sing-box provides the main networking engine and native TUN support, while Xray is used for configurations that require XHTTP or specific REALITY compatibility.

🔗 Subscriptions & Profiles

Import configurations using:

• Subscription URLs • Local files • Pasted configuration text • QR codes • Clash YAML • sing-box JSON • Xray JSON

Subscriptions can refresh automatically, while the last working server list can be retained if an update fails.

🛡️ TUN & Routing

Multik Sila provides system-wide VPN routing through TUN mode.

Routing features include:

• Split tunnelling • Domain and address rules • Service-specific routing • Per-application routing • GeoSite and GeoIP rules • Ad and tracker blocking

On Windows, the application also supports a regular local-proxy mode with automatic system-proxy configuration. TUN mode can be used when applications do not respect system proxy settings.

On Android, VPN traffic is handled through Android's VpnService.

⚙️ Server Selection & Diagnostics

The client includes tools for managing and monitoring connections:

• Latency testing • Automatic server selection • Manual server selection • Live traffic statistics • Active connection information • Network interface and route inspection • Generated core configuration viewer • Connection health monitoring • DNS and IPv6 settings • FakeIP and hosts support • MUX and TLS fragmentation • NTP configuration

The automatic mode can test available servers and select one based on latency. Connection health checks can also react when a selected server stops passing traffic.

🔄 Engine Updates

On Windows, sing-box and Xray engine updates can be downloaded and verified before being applied. On Android, the networking engines are built into the application.

📱 Platforms & Interface

• Android 7.0+ • Windows 10/11 (64-bit) • English and Russian interface • Light and dark themes • Flutter-based UI

🔐 Privacy

According to the project documentation, Multik Sila does not use telemetry, analytics or user accounts. Subscriptions and settings remain on the device. The application communicates with configured subscription servers, connected proxy servers and specific services used for updates, routing rules, latency testing, DNS and optional diagnostics.

⚠️ Important

Multik Sila is a VPN/proxy client, not a VPN service or server provider. Users need compatible proxy configurations, subscriptions or servers. Connection availability and performance depend on the selected server, configuration and network conditions.

✨ Multik Sila combines sing-box and Xray-core with flexible routing, subscription management, diagnostics and system-wide VPN support in a modern cross-platform client.
