Our verdict on Lemin CAPTCHA

Lemin CAPTCHA protects websites from spam bots, brute-force login attacks, credential stuffing and other automated threats with game-based visual puzzles. It is aimed at teams that want a visual challenge option, with boxed, integrated and invisible presentation types. Website owners can customize puzzle imagery and branding, adjust security levels and parameters, and review attack and retention metrics in a real-time dashboard. JavaScript integration and server-side answer verification connect challenges to a site.

Pricing is usage-based. The Free allowance includes up to 5,000 puzzle images per month; after that, additional puzzle images cost $0.001 each. That makes the published pricing straightforward for teams estimating challenge-image volume, though usage beyond the allowance adds variable cost. The product is deployed in the cloud, and its listed platform is web, so it is a fit for website protection rather than teams seeking a broader set of SDK platforms.

The feature set combines challenge presentation choices with customization, adjustable security, and cookie-based skipping for up to 30 days. Accessibility features and privacy controls are listed, and the product lists GDPR compliance. Support channels are email and documentation. Lemin is worth considering for teams that specifically want visual puzzles, an invisible option, and a free monthly image allowance; teams needing non-web platform coverage or a CAPTCHA system centered on a broader integration ecosystem should look elsewhere.
