About our Transition to Closed Source in 2023

Why Closed Source?

To maintain our edge and prevent abuse, we have chosen to restrict source code access to our browser extension. This allows us to continue providing a free-to-use service while protecting our proprietary technology and ensuring the integrity of our CAPTCHA-solving capabilities.

What Changed

We continue to publish the latest builds under GitHub releases and in the Chrome Web Store and Mozilla Add-on store, but the source code for the latest versions will no longer be publicly available.

We have archived the open-source v0.3.x branch for reference, but it is no longer maintained or supported.

The Road Ahead

We are committed to expanding support across CAPTCHA providers and improving accuracy, throughput, and cost efficiency.

Thank you for your understanding and continued support as we evolve our services to better serve our users and maintain the quality and reliability of our CAPTCHA-solving technology.
