Stop proving you're a robot.
Start stamping like a noble.
Legacy CAPTCHAs frustrate your users, drop your conversion rates, and are easily bypassed by modern computer vision bots. Stamptcha replaces boring puzzles with a sensory, high-conversion wax seal ritual. Secure. Tactile. Unforgettable.
Real flame, real wax, real physics
Solid brass, micro-contact physics
Every seal is one of a kind

How the ritual works
Three steps. Four seconds. One token. Your form submits.
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.
Press the signet
The brass stamp descends. Hold to press. The crest engraves itself into the molten pool leaving a unique verification imprint.
Token issued
A signed cryptographic token is generated from your gesture fingerprint and passed to your server for one-call verification.
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.

CAPTCHA MATRIX v1.3.0⚙ Dev Customization Swatches
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.

Answers from the archives
Common questions from developers and security teams.
Yes. Stamptcha collects no cookies, performs no cross-site tracking, and stores no personal data. All behavioral analysis happens locally in the browser. Your server receives only the verification token. We are designed to help you meet GDPR, CCPA, LGPD and other privacy regulations without any additional configuration.
Under 10 minutes. Replace the reCAPTCHA script tag with ours, swap the widget div, and update your server-side verify call. The token response shape is compatible. React and Vue npm packages are available. A WordPress plugin handles the migration in one click.
Stamptcha combines gesture biometrics (mouse velocity, jitter, direction-change frequency) with stamping timing analysis to build a human-probability score. Bots produce statistically perfect, linear movements that score near zero. Our block rate across 1.2M verifications is 99.3%.
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.
Ditch reCAPTCHA this afternoon.
Drop the widget into your site. Point it at our API. Stop paying Google to watch your users — and give them a verification moment they will actually enjoy.
