📦 Installation

go get -u github.com/enetx/surf

Required Go version: 1.24+

🔄 Standard Library Compatibility

Surf provides seamless integration with Go's standard net/http package, allowing you to use Surf's advanced features with any library that expects a standard *http.Client.

// Create a Surf client with advanced features
surfClient := surf.NewClient().
    Builder().
    Impersonate().Chrome().
    Session().
    Build()

// Convert to standard net/http.Client
stdClient := surfClient.Std()

// Use with any third-party library
// Example: AWS SDK, Google APIs, OpenAI client, etc.
resp, err := stdClient.Get("https://api.example.com")

Preserved Features When Using Std():

✅ JA3/TLS fingerprinting
✅ HTTP/2 settings
✅ HTTP/3 & QUIC fingerprinting
✅ Browser impersonation headers
✅ Ordered headers
✅ Cookies and sessions
✅ Proxy configuration
✅ Custom headers and User-Agent
✅ Timeout settings
✅ Redirect policies
✅ Request/Response middleware

Limitations with Std():

❌ Retry logic (implement at application level)
❌ Response body caching
❌ Remote address tracking
❌ Request timing information

🚀 Quick Start

Basic GET Request

package main

import (
    "fmt"
    "log"
    "github.com/enetx/surf"
)

func main() {
    resp := surf.NewClient().Get("https://api.github.com/users/github").Do()
    if resp.IsErr() {
        log.Fatal(resp.Err())
    }

    fmt.Println(resp.Ok().Body.String())
}

JSON Response Handling

type User struct {
    Name     string `json:"name"`
    Company  string `json:"company"`
    Location string `json:"location"`
}

resp := surf.NewClient().Get("https://api.github.com/users/github").Do()
if resp.IsOk() {
    var user User
    resp.Ok().Body.JSON(&user)
    fmt.Printf("User: %+v\n", user)
}

🎭 Browser Impersonation

Chrome Impersonation

client := surf.NewClient().
    Builder().
    Impersonate().
    Chrome().        // Latest Chrome v131
    Build()

resp := client.Get("https://example.com").Do()

Firefox with Random OS

client := surf.NewClient().
    Builder().
    Impersonate().
    RandomOS().      // Randomly selects Windows, macOS, Linux, Android, or iOS
    FireFox().       // Latest Firefox v143
    Build()

Platform-Specific Impersonation

// iOS Chrome
client := surf.NewClient().
    Builder().
    Impersonate().
    IOS().
    Chrome().
    Build()

// Android Chrome
client := surf.NewClient().
    Builder().
    Impersonate().
    Android().
    Chrome().
    Build()

🚀 HTTP/3 & Complete QUIC Fingerprinting

Chrome HTTP/3 with Automatic Detection

// Automatic HTTP/3 with Chrome fingerprinting
client := surf.NewClient().
    Builder().
    Impersonate().Chrome().
    HTTP3().        // Auto-detects Chrome and applies appropriate QUIC settings
    Build()

resp := client.Get("https://cloudflare-quic.com/").Do()
if resp.IsOk() {
    fmt.Printf("Protocol: %s\n", resp.Ok().Proto) // HTTP/3.0
}

Firefox HTTP/3

// Firefox with HTTP/3 fingerprinting
client := surf.NewClient().
    Builder().
    Impersonate().FireFox().
    HTTP3().        // Auto-detects Firefox and applies Firefox QUIC settings
    Build()

resp := client.Get("https://cloudflare-quic.com/").Do()

Manual HTTP/3 Configuration

// Custom QUIC fingerprint with Chrome settings
client := surf.NewClient().
    Builder().
    HTTP3Settings().Chrome().Set().
    Build()

// Custom QUIC fingerprint with Firefox settings
client := surf.NewClient().
    Builder().
    HTTP3Settings().Firefox().Set().
    Build()

// Custom QUIC ID
client := surf.NewClient().
    Builder().
    HTTP3Settings().
    SetQUICID(uquic.QUICChrome_115).

spec, _ := uquic.QUICID2Spec(uquic.QUICFirefox_116)
client := surf.NewClient().
    Builder().
    HTTP3Settings().
    SetQUICSpec(spec).
    Set().
    Build()

HTTP/3 with Complete Fingerprinting

// Combine TLS fingerprinting with HTTP/3 QUIC fingerprinting
client := surf.NewClient().
    Builder().
    JA().Chrome131().               // TLS fingerprint (JA3/JA4)
    HTTP3Settings().Chrome().Set().  // Complete QUIC fingerprint (JA4QUIC)
    Build()

resp := client.Get("https://cloudflare-quic.com/").Do()

HTTP/3 Compatibility & Fallbacks

HTTP/3 automatically handles compatibility issues:

// With HTTP proxy - automatically falls back to HTTP/2
client := surf.NewClient().
    Builder().
    Proxy("http://proxy:8080").     // HTTP proxies incompatible with HTTP/3
    HTTP3Settings().Chrome().Set(). // Will use HTTP/2 instead
    Build()

// With SOCKS5 proxy - HTTP/3 works over UDP
client := surf.NewClient().
    Builder().
    Proxy("socks5://127.0.0.1:1080"). // SOCKS5 UDP proxy supports HTTP/3
    HTTP3Settings().Chrome().Set().   // Will use HTTP/3 over SOCKS5
    Build()

// With DNS settings - works seamlessly
client := surf.NewClient().
    Builder().
    DNS("8.8.8.8:53").             // Custom DNS works with HTTP/3
    HTTP3Settings().Chrome().Set().
    Build()

// With DNS-over-TLS - works seamlessly
client := surf.NewClient().
    Builder().
    DNSOverTLS().Google().          // DoT works with HTTP/3
    HTTP3Settings().Chrome().Set().
    Build()

Key HTTP/3 Features:

✅ Complete QUIC Fingerprinting: Full Chrome and Firefox QUIC transport parameter matching
✅ Header Ordering: Perfect browser-like header sequence preservation
✅ SOCKS5 UDP Support: HTTP/3 works seamlessly over SOCKS5 UDP proxies
✅ Automatic Fallback: Smart fallback to HTTP/2 when HTTP proxies are configured
✅ DNS Integration: Custom DNS and DNS-over-TLS support
✅ JA4QUIC Support: Advanced QUIC fingerprinting with Initial Packet + TLS ClientHello
✅ Order Independence: HTTP3() works regardless of call order
