NopeCHA Chrome Extension & Firefox Add-on
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.

What's Next in 2025
We're excited to announce computer use coming to the NopeCHA API. This new feature will empower developers to send commands and a screenshot of their computer to the API, enabling our model to analyze the input and respond with precise actions. From data scraping to task automation, the updated API will handle a diverse range of operations—going beyond CAPTCHA solving.
With a strong focus on efficiency and speed, this feature will launch in Q1 2025. Developers can leverage it seamlessly, with no concerns about added costs or delays. Stay tuned for more details and updates!
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.
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
:warning: [Outdated examples due to Colab updates]: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.

Development
Prerequisites
Having Python 3.8 or above installed.
Building
To build debug copy for both Chrome and Firefox, simply run the following command:
python build.py
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, build.py 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 build.py command with the -w option so your changes immediately apply:
python build.py -w
or
./build.py -w
Building for production
Prerequisites
npm install uglify-js -g
Build
python build.py -p
Note: The watchdog option -w is also supported here: (python build.py -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.
