!!! warning "Platform Support"

NaiveProxy outbound is only available on Apple platforms, Android, Windows and certain Linux builds.

**Official Release Build Variants:**

| Build Variant | Platforms | Description |
|---------------|-----------|-------------|
| (default)     | Linux amd64/arm64 | purego build with `libcronet.so` included |
| `-glibc`      | Linux 386/amd64/arm/arm64 | CGO build dynamically linked with glibc, requires glibc >= 2.31 |
| `-musl`       | Linux 386/amd64/arm/arm64 | CGO build statically linked with musl, no system requirements |
| (default)     | Windows amd64/arm64 | purego build with `libcronet.dll` included |

**Runtime Requirements:**

- **Linux purego**: `libcronet.so` must be in the same directory as the sing-box binary or in system library path
- **Windows**: `libcronet.dll` must be in the same directory as `sing-box.exe` or in a directory listed in `PATH`

Fields

server

==Required==

The server address.

server_port

==Required==

The server port.

username

Authentication username.

password

Authentication password.

insecure_concurrency

Number of concurrent tunnel connections. Multiple connections make the tunneling easier to detect through traffic analysis, which defeats the purpose of NaiveProxy's design to resist traffic analysis.

extra_headers

Extra headers to send in HTTP requests.

udp_over_tcp

UDP over TCP protocol settings.

See UDP Over TCP for details.

tls

==Required==

TLS configuration, see TLS.

Only server_name, certificate, certificate_path and certificate_public_key_sha256 are supported.
