STAMPTCHA

Wax Seal CAPTCHA
⚔ Now in early access — be one of the first to seal

Stop proving you're a robot.
Start stamping like a noble.

Stamptcha trades squint-and-click puzzles for a 4-second wax-seal ritual — pour the wax, trace the signet, press. Effortless for humans, unforgeable for bots.

How the ritual works

Three steps. Four seconds. One token. Your form submits.

Step I

Melt the wax

Hover over the parchment. The candle appears. Hold and drag to trace the golden runic path and pour hot wax onto the seal zone.

Step II

Press the signet

The brass stamp descends. Hold to press. The crest engraves itself into the molten pool leaving a unique verification imprint.

Step III

Token issued

A signed cryptographic token is generated from your gesture fingerprint and passed to your server for one-call verification.

✦ Conversion science

Gamify your conversions.
Humanize your experience.

Every other CAPTCHA punishes users for existing. Stamptcha gives them a 4-second moment of craft — pour the wax, press the seal, done. That ritual is not just a security gate. It is a brand touchpoint that makes your product feel premium, intentional, and alive.

Other CAPTCHAs make your site feel like a government portal. Stamptcha makes it feel like a private members' club.

The Identity Layer

Design your seal once.
Stamp everywhere.

Create a Stamptcha account and design your personal seal — your crest, your color, your engraving. On any site using Stamptcha, your seal appears pre-loaded. One press. Instantly verified. No puzzle to solve.

The bot filter happens at registration — once you are verified as human, every future stamp is already trusted. It is how passkeys work. It is how trusted identity should work.

How Stamptcha Outperforms Legacy Solutions

Say goodbye to traffic lights, crosswalks, and high cart-abandonment rates.

Security Criterion Stamptcha reCAPTCHA v3 hCaptcha
User Friction & UX Delightful physical tactile ASMR Frustrating background cookies Annoying static object grids

Human Motion Analysis

Tracing the rune produces natural variance in speed, direction, and timing that scripts struggle to fake. The server scores every gesture before issuing a signed token.

Zero-Cookie Compliance

We do not track, fingerprint, or sell user profiling details. Stamptcha functions completely mathematically and locally, aligning perfectly with GDPR protocols.

Tactile Loyalty Brand Boost

Allow customers to feel a sense of security and premium touch. Customize colors, wax shapes, and signet text directly to fit your digital storefront.

Answers from the archives

Common questions from developers and security teams.

Yes, by design. Stamptcha sets no cookies, performs no cross-site tracking, and stores no personal data. Verification uses only anonymous motion measurements — never identity — and your server receives just a signed token. That design keeps you well positioned for GDPR, CCPA, LGPD and similar privacy regulations.

The goal is under 10 minutes: replace the reCAPTCHA script tag with ours, swap the widget div, and update your server-side verify call — one script, one div, one API call. React and Vue packages plus a WordPress plugin are on the roadmap; early access members shape which ships first.

Stamptcha analyzes gesture dynamics (velocity, jitter, direction-change frequency) and stamping timing on the server before issuing a signed, single-use token. Scripts produce statistically perfect, linear movements that score near zero. We're in early access — we'll publish real-world block rates as the data comes in, not made-up ones.

Coming in the next release. Users create a Stamptcha account and design their own personal seal. On any site using Stamptcha, their seal appears pre-loaded — one press verifies them instantly, no puzzle required. Bot-filtering happens once at registration. Every subsequent stamp across every site is pre-trusted, like a passport at a border crossing.

Yes. The seal ritual is fully touch-enabled. Users drag with a finger to trace the golden path, then press to stamp. Touch gesture data is analyzed identically to mouse data. Mobile users often find it more natural — tracing on glass feels like an actual wax pour.

Be first to ditch reCAPTCHA.
