Modern web scraping and browser automation are in a constant arms race against anti-bot systems. Today's CAPTCHAs (like reCAPTCHA v3, Cloudflare Turnstile, and Arkose Labs) rely heavily on behavioral analysis, risk scoring, and browser fingerprinting. The classic Optical Character Recognition (OCR) approach for solving distorted text is no longer sufficient for successful automation.

In this article, we’ll explain how captcha works, and what bypass methods are used in scenarios such as testing, QA, automation, and anti-bot protection analysis.

Learn how to set up automated CAPTCHA solving in your local OpenClaw AI assistant using the 2Captcha browser extension. A step-by-step zero-code guide, Chromium setup, and AI prompting tips.

This article explains how to integrate a captcha solving API with Cypress to automatically bypass captchas in end-to-end tests.

1. A captcha solver is a service or tool that completes CAPTCHA challenges using AI or human workers. Learn how solvers work, what they return (answers vs tokens), API vs browser extensions, common triggers, and key limitations.

We’ve added ALTCHA solver support — you can now solve it via our API. Send the site data, receive the answer, and automate workflows on target sites.

To combat automation, websites are implementing increasingly complex types of captchas. One such captcha is the Rotate captcha (RotateSlider), where the user must correctly rotate an image to align it with the target fragment.

This captcha, for example, is used on OOCL.com, and solving it manually significantly slows down workflows. Fortunately, we already provide a reliable API for automatic rotation angle detection.

We’ve added Temu captcha bypass support — you can now solve Temu via our API. Submit the site data, receive the solution, and automate workflows on target sites.

We are proud to announce the official launch of our new game — a platform where everyday work turns into progress, competition, and real earnings.

We’ve updated the Software section: a new design, more traffic from search results, full re-moderation of all listings, and moderated user comments.
