Stitex Captcha is a cloud service for adding CAPTCHA and bot protection to website forms. It is aimed at web teams that want to combine behavioral checks with visual challenges, rather than relying on a single challenge type. A JavaScript widget handles the form-side experience, while a REST API supports server-side token verification. The product also offers invisible checks for trusted visitors and a proof-of-work challenge after repeated failures, making its approach a mix of visible and less visible defenses.

Its range of challenge and scoring options is a notable distinction. Behavioral analysis considers mouse and keyboard activity and solve time; antifraud scoring can adjust difficulty, and visual challenges include math, text-sequence, and pattern formats. The Free plan includes one site, basic antifraud and fingerprinting, invisible CAPTCHA, and no request limit. According to the vendor’s pricing page, Pro costs 1,990 RUB per month or 19,900 RUB per year, with VAT included. It supports up to 10 sites and adds ML bot scoring, geo analytics, attack alerts, and server-side form validation. Enterprise includes unlimited sites, custom rules, SLA, and priority support; pricing is by request. The published plans make the free tier a starting point for a single site, while multi-site management and the additional controls sit in paid tiers.

Integration is oriented toward web forms and server-side verification: documentation includes REST API examples for PHP, Python, Node.js, and curl. Dashboard analytics cover conversions, calls, and errors. Support is offered by email and documentation. Teams seeking behavioral and risk-based checks alongside visual challenges may find the feature mix relevant; those requiring audio challenges should look elsewhere, since Stitex Captcha does not offer them. Its documented SDK platform is web, so organizations seeking broader native-platform SDK coverage may also prefer an alternative.
