adCAPTCHA

adCAPTCHA, built by adCAPTCHA Ltd. in the UK, replaces the usual distorted-text or image-grid CAPTCHA with short video or image challenges that also double as ad space. The company's four-layer security approach blocks bots -- credential stuffing, spam bots, scalping bots, card-testing bots, and affiliate fraud -- while presenting media that a website or its advertisers control, rather than a fully generic test. Because challenges use branded media, the company positions adCAPTCHA as filling two roles at once: bot protection, and a channel to display video or image content to a verified human audience in portrait or landscape formats. adCAPTCHA states it does not track user behavior, collect personal information, or set cookies -- a contrast with some behavioral-analysis CAPTCHA services that inspect user activity across a session. Developers integrate it through a documented API with prebuilt libraries for Node.js, PHP, React, Vue, Svelte, and Angular, with the company claiming setup can be completed in minutes. It is aimed at e-commerce sites and publishers that want bot protection without degrading the checkout or reading experience with slow, frustrating puzzles. One tradeoff worth noting: pricing is not published on the site, so cost depends on a sales conversation rather than self-serve signup.
