captcha.cc is a privacy-first CAPTCHA service positioned as a CAPTCHA that “doesn’t steal user data.” It explicitly states that it does not store IP addresses, fingerprints, or browsing behavior; challenges are forgotten after verification, and users are not asked to label images for AI. Its CAPTCHA format is a readable image challenge, suitable for basic anti-spam and anti-abuse scenarios such as website forms, sign-ups, logins, and comments.
In terms of protection types, it offers image CAPTCHAs, one-time-use answers to prevent replay, rate limiting, abuse protection, and domain restrictions. Deployment is lightweight: on the browser side, you can create a challenge with @captchacc/browser or use plain HTML; on the server side, you verify the proof token by calling /v1/siteverify with a secret key. The documentation covers Node/Express, Next.js, PHP, WordPress, and Cloudflare Workers, and it also provides a WordPress starter plugin, making integration relatively straightforward.
Pricing is split into Free and Enterprise plans. The free plan is aimed at regular production websites and includes unlimited sites, a JS SDK, a simple API, global delivery, domain restrictions, and related guides. The Enterprise plan targets high-traffic and centrally managed environments, offering advanced policy controls, organization and role management, SSO, audit trails, operator logs, custom hostnames, priority support, an SLA, procurement support, security review, invoicing, and migration assistance. Enterprise pricing is not public and requires contacting [email protected].
Its strengths are a clear privacy commitment, avoiding logs, tracking, and data harvesting; broad coverage in the free plan; fairly complete integration materials; and basic management and audit capabilities in the Enterprise plan. Limitations include the lack of publicly stated compliance certifications, company location, specific availability SLA figures, detection performance metrics, accessibility capabilities, and Enterprise pricing. Support capabilities are also mainly reflected in the Enterprise plan.
It is suitable for small and medium-sized websites that care about user privacy, want to quickly replace reCAPTCHA or hCaptcha, and do not need complex behavioral risk control. The Enterprise plan is better suited to high-traffic teams that require SSO, auditing, and procurement workflows. Access from mainland China cannot be determined from the available text, so it is recommended to test connectivity, latency, and payment/invoicing processes before going live. If there are access or compliance requirements, alternatives such as Tencent Cloud CAPTCHA, Alibaba Cloud CAPTCHA, GeeTest, or Cloudflare Turnstile may also be worth evaluating.
