kdriver

This project is a Kotlin port of Python library zendriver, built to bring the same simplicity and power of CDP-based automation to the Kotlin and Java/JVM world.

kdriver is a blazing fast, coroutine-first, undetectable web scraping / browser automation library for Kotlin. It uses the Chrome DevTools Protocol (CDP) under the hood to interact with real Chrome instances, offering a sleek alternative to heavy tools like Selenium or Puppeteer — all without relying on WebDriver.

Features

• Undetectable – Like its Python counterpart, kdriver speaks CDP directly, making it (almost) impossible for sites to detect.
• Blazing fast – CDP is lightweight and extremely performant. Combined with Kotlin coroutines, you get low-latency scraping and automation.

Motivation

We chose Kotlin for this port because:

• First-class type safety and null safety help catch bugs early and make the code more robust.
• It's the core language of our entire stack (backends, Android apps, shared libraries).
• Multiplatform support is on the roadmap, allowing future compatibility with native and JS targets. (Currently JVM-only)

Installation

To use kdriver, add the following to your build.gradle.kts:

dependencies {
    implementation("dev.kdriver:core:0.5.11")
}

Make sure you have Maven Central configured:

repositories {
    mavenCentral()
}

Usage

Visit a website and do something on it:

fun main() = runBlocking {
    val browser = createBrowser(this)
    val page = browser.get("https://www.browserscan.net/bot-detection")
    page.saveScreenshot(Path("browserscan.png"))
    browser.stop()
}

More examples can be found on the tutorial section of the documentation.

Acknowledgments

Huge thanks to @stephanlensky for creating zendriver, a brilliantly designed and maintained library that inspired this port. If you're using Python, we highly recommend checking out the original project!

Goals of the project

The purpose of kdriver is to provide a clean, coroutine-native API for browser automation in Kotlin, while staying true to the goals of zendriver:

1. Stay undetected in modern anti-bot environments
2. Offer a developer-friendly experience with minimal setup
3. Empower developers with a flexible, low-level browser interface

This library is still in early development — feedback and contributions are very welcome!
