Privacy-first human verification that swaps annoying puzzles for engaging images and video.
Verify visitors with short image and video interactions instead of text or grid puzzles, using media you upload through the dashboard.
Multiple detection layers run behind a single interaction to catch sophisticated bots without adding friction for genuine users.
Turn the verification moment into a positive touchpoint by featuring your own media, or open the space to advertisers.
Pre-built integrations for popular platforms plus a documented API let teams add human verification to a site or app in minutes.
Solve reCAPTCHA, Cloudflare and more in under 0.7 seconds
Advertised solve times under 0.7 seconds for most CAPTCHA types, so automation scripts do not stall waiting on a challenge.
Handles reCAPTCHA v2, AWS WAF, GeeTest v4, Cloudflare Turnstile, TikTok CAPTCHA and image-to-text puzzles from a single API.
A REST API plus a Chrome extension and documented support for Puppeteer, Playwright and Selenium.
A free tier that is generous enough to test an integration end to end before committing to a paid bucket.
