NopeCHA Chrome Extension & Firefox Add-on

PyPI - Version NPM Version GitHub Release Chrome Web Store Version Mozilla Add-on Version

NopeCHA is a free-to-use automated CAPTCHA solver, compatible with multiple CAPTCHA types, and powered by advanced deep learning models via the NopeCHA API.

Why NopeCHA?

Staying up-to-date with frequently changing CAPTCHA challenges can be tedious. That's why we've developed browser extensions for both Chrome and Firefox. These extensions receive regular updates to support the latest CAPTCHA challenges, ensuring uninterrupted service for your automation scripts. Once installed, NopeCHA autonomously handles CAPTCHAs, allowing you to focus on more important tasks.

Getting Started

For developers interested in integrating NopeCHA into their projects, please consult our API documentation.

To test the extension:

Supported CAPTCHA Types

Here's a sample of CAPTCHA types supported by NopeCHA, with more being added regularly:

All versions of reCAPTCHA Most versions of FunCAPTCHA
All versions of hCaptcha AWS WAF CAPTCHA
300+ Types of Text CAPTCHA Cloudflare Turnstile
Text-based CAPTCHA Cloudflare Turnstile

Important Update: Transition to Closed-Source in 2023

What's New?

Starting 2023, NopeCHA has transitioned to a closed-source model. Despite this, we will continue to publish the latest builds under Releases.

Why the Transition?

Earlier this year, hCaptcha and FunCAPTCHA added a hardcoded check to detect NopeCHA v0.3.x and open-source softwares developed by NopeCHA, LLC. This attention validates our impact. To maintain our edge without offering CAPTCHA providers a counter-strategy, we have chosen to restrict source code access.

Technical Advancements

Behind the scenes, NopeCHA is undergoing intense training and refinement. Our neural network architecture continuously adapts to new challenges. Whether it's decoding obscure characters or solving complex image-to-image tasks, NopeCHA is built for it.

The Road Ahead

We're committed to refining our algorithms and expanding our library of solved CAPTCHAs. While our advanced machine learning models give us a definitive edge, the story isn't over. We will continue to push the boundaries of what's possible in CAPTCHA-solving technology.

Thanks for your support, and remember—in a world full of CAPTCHAs, be a NopeCHA. 😎✌️

Usage Examples

⚠️ [Outdated examples due to Colab updates]:

While it's possible to use NopeCHA in Colab, we're not actively supporting it. If you're interested in using NopeCHA in Colab, you will need to change the code to get it working again.

Having Python 3.8 or above installed.


To build debug copy for both Chrome and Firefox, simply run the following command:


This will create a dist directory in the project root directory, in which you will find firefox and chrome directories for debugging purposes. If you use the -p argument, each debugging directory will have an additional xpi/crc archive for production usage.

Actively listening for changes

For development convenience, also supports listening to changes so files are quickly updated.

For that, you need to install python's watchdog in your machine:

python -m pip install watchdog

Then you can run command with the -w option so your changes immediately apply:

python -w or ./ -w

Building for production


npm install uglify-js -g


python -p

Note: The watchdog option -w is also supported here: (python -pw)

Minified code for production can be found in the .zip files in the corresponding browser directory. The zip files can be used for final testing/debugging before sending them to the webstores.
