reCAPTCHA Solver

Solve reCAPTCHA challenges by using offline speech recognition.

It can be very useful when you want to do E2E tests with your application protected by reCAPTCHA.

Forked from JacobLinCool/recaptcha-solver

Added ffmpeg as dependancy took inspiration from dxball/recaptcha-solver

Now ffmpeg is installed as a dependancy

Features:

• Offline: A pretrained small model is included.
• Fast: Solve each challenge in less than 3 seconds.
• Accurate: Over 95% accuracy.
• Auto-retry: If the challenge is not solved, it will retry it.
• Supports reCAPTCHA v2 and v3 (invisible).

Install

npm i recaptcha-solver-ffmpeg

It will automatically download a 40 MB acoustic model which will be used to solve the challenges.

The model is from https://alphacephei.com/vosk/models (Apache 2.0).
