How to Use the 2captcha-solver Plugin in Puppeteer


In the previous article, I introduced a useful captcha service 2Captcha, and wrote a tutorial and a review article. For those who don't know 2Captcha, you can read these two articles first.

In this article we will describe how to use the 2captcha-solver plugin together with Puppeteer.

Puppeteer is a Node library that allows you to launch a browser and perform various actions in it, usage examples are described here. Library Puppeteer is great for various kinds of automations, writing parsers and other tasks where automatization in the browser is necessary. Advantage of Puppeteer is its simplicity and the ability to work in headless mode. There are ready-made solutions for Puppeteer that allow you to hide the fact of automation. Hiding the fact of automation is important when development parsers, as this will allow the browser to look more like a person and not be exposed.

In this article we will use Puppeteer, puppeteer-extra and puppeteer-extra-plugin-stealth. puppeteer-extra is a lightweight wrapper around Puppeteer, and puppeteer-extra-plugin-stealth is an addition to puppeteer-extra designed to hide traces of automation.

In the step-by-step description below, we will describe how to solve the captcha on the page


1. Install components

Installing Puppeteer and other required packages:

npm i puppeteer puppeteer-extra puppeteer-extra-plugin-stealth

2. Setting up the plugin

Download archive with the plugin, and unzip it to the folder "/2captcha-solver" in the root of the project.

The plugin has many settings, including automatic solution of the specified type of captcha, support for proxy, and other settings. The settings are available in the file /common/config.js. To add settings for the automatic reCAPTCHA V2 solution, you need to open the file /common/config.js and change the value of the autoSolveRecaptchaV2 field to true.

Next, you need to configure the plugin:

  1. Enter your API key in the plugin settings file ./common/config.js. Your key must be written to the value of the apiKey field. You can see and copy you're API key on the page.

    Example: apiKey: "8080629c1221fdd82m8080000ff0c99c"

  2. Disable opening the extension settings page after installation. To do this, in the file ./manifest.json delete the following lines:

    "options_ui": {
        "page": "options/options.html",
        "open_in_tab": true

3. Browser Automation

Launching and initializing the plugin in Puppeteer:

const puppeteer = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');

(async () => {
  const pathToExtension = require('path').join(__dirname, '2captcha-solver');
  const browser = await puppeteer.launch({
    headless: false,
    args: [
  const [page] = await browser.pages()

3.1 Opening a page

Opening a page, and sending a captcha.

Using page.goto() we go to the page Next, you need to send a captcha for a solution, this can be done manually or automatically.

In our example, we will send a captcha manually, for this we wait until the plugin button with the CSS selector .captcha-solver is available, then click on this button. After clicking on the button, the captcha will go to the service for a solution.

// Opening a page
await page.goto('') 

// Waiting for the element with the CSS selector ".captcha-solver" to be available
await page.waitForSelector('.captcha-solver')

// Click on the element with the specified selector

3.2 Checking the captcha status

After receiving a response from the service, the plugin button .captcha-solver will change the value of the data attribute data-state. By observing the value of this data-state attribute, you can monitor the state of the plugin. After solving the captcha, the value of this attribute will change to "solved".

Description of the values of the data-state attribute:

data-state="ready"The plugin is ready to solve the captcha. To send a captcha, you need to click on the button.
data-state="solving"Solving the captcha.
data-state="solved"Captcha has been successfully solved
data-state="error"An error when receiving a response or a captcha was not successfully solved.

At this step, you need to wait until the captcha is solved, after that the attribute value will change to "solved", this will signal the successful solution of the captcha. After this step, you can do the necessary actions.

// By default, waitForSelector waits for 30 seconds, but this time is usually not enough, so we specify the timeout value manually with the second parameter. The timeout value is specified in "ms".
await page.waitForSelector(`.captcha-solver[data-state="solved"]`, {timeout: 180000})

4. Doing actions

After solving the captcha, we can start doing the necessary actions on the page. In our example, we will click on the "Check" button to check the correctness of the received captcha solution. After successfully passing the check, you will see the message "Captcha is passed successfully!".

// Click on the "Check" button to check the successful solution of the captcha.

Congratulations, the captcha has been successfully passed! The full source code of the example is here: openHacking/2captcha.

Of course, the steps will be simpler if you directly pull the source code to run.

# pull code
git clone
cd 2captcha
# install dependencies
npm i
# run directly
node index.js

Useful information

  • The plugin has many settings, for example, automatic solution of the specified type of captcha or support for proxy, all these settings are available in the file /common/config.js, in the folder with the unpacked plugin. To automatically send reCAPTCHA V2, in the file /common/config.js change the value of the autoSolveRecaptchaV2 field to true.

  • You can use sandbox mode, for testing. In sandbox mode, sent captchas will be sent to you. Learn more about sandbox you can read here.

  • Puppeteer running in headless mode does not support loading plugins, to solve this problem you can use xvfb.
