ktor-impersonate (WIP)

This project is currently under development and is not ready for usage!

A Kotlin-Multiplatform (KMP)¹ Ktor client engine that binds to the rquest (aka. reqwest-impersonate) Rust crate, allowing configuring the TLS ClientHello and HTTP/2 options at a low level.

This allows impersonating browsers and other HTTP clients with ease, and spoofing JA3/JA4/Akamai HTTP/2 fingerprints. Presets are provided for convenience of Chrome, Safari, Edge, and OkHTTP.

^{1: Currently only Android (x86, x86_64, armeabi-v7a, arm64-v8a) is supported. More platforms, including JVM, Desktop native, and iOS, will be supported at a later date.}

Usage

build.gradle.kts:

val version = "1.0.0"

// Without KMP
dependencies {
  implementation("dev.rushii.ktor-impersonate:ktor-impersonate:$version")
}

// KMP
kotlin {
  sourceSets {
    commonMain.dependencies {
      implementation("dev.rushii.ktor-impersonate:ktor-impersonate:$version")
    }
  }
}

Quick start:

import dev.rushii.ktor_impersonate.*
import io.ktor.client.*
import io.ktor.client.request.*

val client = HttpClient(Impersonate) {
  engine {
    preset = ImpersonatePreset.Chrome129
  }
}

client.get("https://google.com")
