AI-powered CAPTCHA solving API built for scale
Supports reCAPTCHA v2/v3 and Enterprise, Cloudflare Turnstile and Bot Challenge, AWS WAF, GeeTest, Tencent CAPTCHA, Yidun, Text CAPTCHA and more.
Integrate with official libraries for C#, Python, JavaScript, Go, and PHP, or use the API of other services via compatibility.
Chrome and Firefox extensions detect and solve CAPTCHAs automatically in the background while you browse.
Most challenge types can be solved without supplying your own proxies, simplifying setup.

Real-time vision AI models and a full platform to train, annotate, and deploy them
One model family covering detection, instance segmentation, pose estimation, oriented boxes, classification, and tracking, tuned for real-time inference on GPU, CPU, and edge devices.
Label data with SAM-assisted annotation, train on cloud GPUs with AutoTrain, and deploy to managed regions that scale to zero when idle.
Ship trained models to ONNX, TensorRT, CoreML, TFLite, and many other formats for cloud servers, mobile devices, and embedded hardware.
Adopt the open-source AGPL-3.0 release, or purchase an enterprise license to embed YOLO in closed-source products without copyleft obligations.
