Symfony DecaptchaBundle is a Symfony package that lets developers integrate multiple CAPTCHA-solving services (like 2Captcha, AntiCaptcha, etc.) into one standardized interface for easier switching and configuration.

Yes, the bundle itself is free and open-source. However, using external CAPTCHA-solving services requires paid API keys from providers like CaptchaAI.

Support depends on the backend services you configure. Most services support image-based CAPTCHAs and reCAPTCHA v2/v3. hCaptcha, audio, or more complex challenges depend on provider capabilities.

Yes. DecaptchaBundle lets you define multiple services and fallback logic if one fails. You can even prioritize faster or more reliable services.

Each provider requires its own configuration (API key, method, URL, etc.). You’ll need to check the specific service documentation, including CaptchaAI’s API docs.

The bundle is designed to switch to the next configured provider if the current one fails, as long as you've set up fallback logic properly.

While it works well, the GitHub repository is not actively maintained. It's recommended for technical users who can troubleshoot issues or contribute fixes.

No. The bundle acts as a relay between your Symfony app and the external service. All CAPTCHA data remains external unless you explicitly store results.

Unlike some outdated or unstable CAPTCHA solvers, CaptchaAI offers stable endpoints, rich module support (e.g., image, reCAPTCHA, FunCaptcha), and optional parameters like user-agent, cookies, and proxy. These improve success rates, especially when other providers fail or are blocked.

Many users report failures like ERROR_CAPTCHA_UNSOLVABLE or long delays from other services. CaptchaAI helps mitigate these with smarter error handling, transparent API docs, and flexible parameters. For example, it avoids common pitfalls like thread exhaustion and lets users fine-tune solves by passing headers or proxy details.
