captcha recognition OCR
DdddOcr is an offline Python library that uses deep learning to recognize common CAPTCHAs (text, sliders, etc.) with a simple API.
Solves the same problem with a different architecture or at a different layer. Expect to rewrite the integration.
Self-hosted model deployment platform for captcha recognition when you need a server/API rather than embedding a library.
[验证码识别-部署] This project is based on CNN+BLSTM+CTC to realize verificationtion. This projeccode identificat is only for deployment models.
PHP captcha recognition library, chosen by PHP developers instead of Python ddddocr.

Older C++ captcha-break using tesseract/opencv, for legacy or academic use.
captcha break based on opencv2, tesseract-ocr and some machine learning algorithm.
Old Jupyter notebook captcha recognition implementation, less ready-to-use than ddddocr.

Does the same job, but ships as an app. Useful to a person, not swappable into a codebase.
A standalone pentesting tool to bypass captchas, for end-users not library integration.
Captcha Intruder (CIntrud3r) is an automatic pentesting tool to bypass captchas.
These projects were analysed and named ddddocr among their alternatives. The relationship is not symmetric — how ddddocr rates them is a separate judgement, made when ddddocr is analysed in its own right.
calls ddddocr “captcha-specific OCR library; narrow but perfect for captcha solving”
