Challenge the gates · meet the detector

Every gate falls to the right bot.
The detector convicts it anyway.

Every bot-blocking gate on the web — proof-of-work, CAPTCHA, sliders, personhood tokens — rebuilt here on our own infrastructure. Bring a browser, a bot, or your own solver and beat one. You get two verdicts: whether you passed the gate, and whether Kitsune still knows what you are.

Solving a gate proves you paid the cost or passed the puzzle — not that you’re human. A script can beat every gate here and still get caught. The puzzle is theatre; the fingerprint is the tell.

How this works & the ethics

The gate is a self-hosted service Kitsune runs (the owned arena service). It reproduces the documented, open mechanism above — it never contacts, proxies to, or solves a third-party challenge (Cloudflare Turnstile, reCAPTCHA, hCaptcha). The reference solvers only ever talk to our own gates. The detector verdict comes from the same coherence engine that scores the home page, reading your client over the edge.
