- Captcha recognition on OCR algorithms
- Ready module base, constant updates
- Custom modules for virtually any captcha
- Saves on third-party recognition services
- Integrates with ZennoPoster and other software
CapMonster runs locally on your own hardware and does not charge per request: set it up once and recognition runs without limits and without depending on third-party servers. This matters most at high volumes in ZennoPoster and other tools, where captcha appears at almost every step and the speed and cost of recognition directly affect the result.
Captcha solving at scale often runs alongside automation and checkers, and stable proxies help hold the pace without drops.
