Kameleo Local API Client

With Kameleo, you can easily create multiple virtual browser profiles to work with multiple accounts. It helps you hide your actual timezone, geolocation, language, IP address and creates natural browser fingerprints to prevent detection by anti-bot systems. Kameleo is compatible with Selenium, Playwright, and Puppeteer frameworks for automating web scraping tasks. This .NET Standard package provides convenient access to the Local API REST interface of the Kameleo Client. See the article in our knowledge base for Getting Started with Kameleo Automation.

Features

• Stay completely undetected, so websites won't be able to detect that you are using automation tools
• Start unlimited number of profiles with different natural browser fingerprints
• Use authenticated HTTP/SOCKS/SSH proxies in browsers
• Create isolated browsing environments simultaneously
• Use real browser profiles of Chrome, Firefox, Safari and Edge
• Edit, Import or Export browser cookies
• Modify WebRTC parameters
• Modify Geolocation settings
• Modify Timezone and Language settings
• Modify WebGL fingerprint
• Modify 2D Canvas fingerprint
• Modify Navigator properties
• Modify Screen resolution

Note: You need Automation package of Kameleo to access the features described below.

Quickstart Guide

1. Install by NuGet

Install-Package Kameleo.LocalApiClient

2. Start the Kameleo.CLI on your computer

./Kameleo.CLI.exe email="[email protected]" password="Pa$$w0rd"

3. Start a browser with out-of-the-box fingerprinting protection

using System;
using System.Threading.Tasks;
using Kameleo.LocalApiClient;

namespace Kameleo.QuickstartGuide
{
    class Program
    {
        private const string KameleoBaseUrl = "http://localhost:5050";

        static async Task Main()
        {
            var client = new KameleoLocalApiClient(new Uri(KameleoBaseUrl));
            client.SetRetryPolicy(null);

            // Search Chrome Base Profiles
            var baseProfiles = await client.SearchBaseProfilesAsync(
                deviceType: "desktop",
                browserProduct: "chrome");

            // Create a new profile with recommended settings
            // for browser fingerprint protection
            var requestBody = BuilderForCreateProfile
                .ForBaseProfile(baseProfiles[0].Id)
                .SetRecommendedDefaults()
                .Build();

            var profile = await client.CreateProfileAsync(requestBody);

            // Start the browser
            await client.StartProfileAsync(profile.Id);

            // At this point you can automate the browser with your favorite framework
        }
    }
}

Automate Kameleo profiles with Selenium

Kameleo gives you the ability to control any supported browser using Selenium. It uses the WebDriver protocol, a W3C specification, and industry-standard to interact with a browser.

You need to install the official Selenium package.

using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Remote;

const int KameleoPort = 5050;

// Connect to the running browser instance using WebDriver
var uri = new Uri($"http://localhost:{KameleoPort}/webdriver");
var opts = new ChromeOptions();
opts.AddAdditionalOption("kameleo:profileId", profile.Id.ToString());

var webdriver = new RemoteWebDriver(uri, opts);

// Use any WebDriver command to drive the browser
// and enjoy full protection from bot detection products
webdriver.Navigate().GoToUrl("https://google.com");

The full example can be found here.

Automate Kameleo profiles with Puppeteer (Chromium-based)

Kameleo lets you control Chromium-based browsers (sorry Firefox fans) using the Puppeteer.Sharp package. In this simple example you can see how to connect to the browser that Kameleo starts.

You need to import the Puppeteer.Sharp.

using PuppeteerSharp;

// Connect to the browser through CDP
const int KameleoPort = 5050;

var browserWsEndpoint = $"ws://localhost:{KameleoPort}/puppeteer/{profile.Id}";
var browser = await Puppeteer.ConnectAsync(new ConnectOptions {
    BrowserWSEndpoint = browserWsEndpoint,
    DefaultViewport = null });

var page = await browser.NewPageAsync();

// Use any Puppeteer command to drive the browser
// and enjoy full protection from bot detection products
await page.GoToAsync("https://google.com");

The full example can be found here.

Automate Kameleo profiles with Playwright

Kameleo allows you to control the browser with the official Playwright package. It works little bit different with Chromium-based browsers and Firefox, so we provide an example for both. Here we showcase how you can connect to the browser that is already started by Kameleo.

You need to import the official Playwright package.

using Microsoft.Playwright;

You can find more details here: Using Kameleo with Playwright framework – Kameleo Support Center.

Chromium-based profiles with Playwright

// Connect to the browser with Playwright through CDP
const int KameleoPort = 5050;

var browserWsEndpoint = $"ws://localhost:{KameleoPort}/playwright/{profile.Id}";
var playwright = await Playwright.CreateAsync();
var browser = await playwright.Chromium.ConnectOverCDPAsync(browserWsEndpoint);

// It is recommended to work on the default context.
// NOTE: We DO NOT recommend using multiple browser contexts, as this might interfere
//       with Kameleo's browser fingerprint modification features.
var context = browser.Contexts[0];
var page = await context.NewPageAsync();

// Use any Playwright command to drive the browser
// and enjoy full protection from bot detection products
await page.GotoAsync("https://google.com");

The full example can be found here.

Firefox-based profiles with Playwright

// Connect to the browser with Playwright
const int KameleoPort = 5050;

var browserWsEndpoint = $"ws://localhost:{KameleoPort}/playwright/{profile.Id}";
var playwright = await Playwright.CreateAsync();
// The exact path to the bridge executable is subject to change. Here, we use %LOCALAPPDATA%\Programs\Kameleo\pw-bridge.exe
var localAppDataFolder = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
var executablePath = Path.Combine(localAppDataFolder, "Programs", "Kameleo", "pw-bridge.exe");
var browser = await playwright.Firefox.LaunchPersistentContextAsync("", new BrowserTypeLaunchPersistentContextOptions
{
	// The Playwright framework is not designed to connect to already running
	// browsers. To overcome this limitation, a tool bundled with Kameleo, named
	// pw-bridge.exe will bridge the communication gap between the running Firefox
	// instance and this playwright script.
	ExecutablePath = executablePath,
	Args = new List<string> { $"-target {browserWsEndpoint}" },
	ViewportSize = null,
});

// Kameleo will open the a new page in the default browser context.
// NOTE: We DO NOT recommend using multiple browser contexts, as this might interfere
//       with Kameleo's browser fingerprint modification features.
var page = await browser.NewPageAsync();

// Use any Playwright command to drive the browser
// and enjoy full protection from bot detection products
await page.GotoAsync("https://google.com");

The full example can be found here.

Automate mobile profiles

Kameleo can emulate mobile devices in the custom built Chromium.

var baseProfileList = await client.SearchBaseProfilesAsync(
	"mobile",
	"ios",
	"safari",
	"en-us");

// Create a new profile with recommended settings
// Choose one of the Base Profiles
// Set the launcher to 'chromium' so the mobile profile will be started in Chroma browser
var createProfileRequest = BuilderForCreateProfile
	.ForBaseProfile(baseProfileList[0].Id)
	.SetRecommendedDefaults()
	.SetLauncher("chromium")
	.Build();

var profile = await client.CreateProfileAsync(createProfileRequest);

// Start the profile with a couple of extra parameters, so Selenium automation can be done fluently
await client.StartProfileWithOptionsAsync(profile.Id, new WebDriverSettings()
{
	AdditionalOptions = new List<Preference>
	{
		// This allows you to click on elements using the cursor when emulating a touch screen in the brower.
		// If you leave this out, your script may time out after clicks and fail.
		new Preference("disableTouchEmulation", true),
	}
});

// At this point you can automate the browser with your favorite framework
