Public proof · Owned identity · Consent evidence · Signatures
Prove who agreed, what they saw, and when it happened.
CapchaCloud gives businesses a public evidence trail for sign-ins, consent forms, and signed documents. Each workflow can create a hashed record, certificate, export, and verification path that customers, counsel, and operators can test.
Built on Cloudflare Workers, D1, R2, Turnstile, Stripe, Google sign-in, email sign-in, and CapchaID.
Public certificate
Consent proof record
A customer-safe page can show the evidence fingerprint and verification result without exposing your private dashboard.
Example counsel packet
Give counsel the record, not a screenshot.
Open a sample packet and inspect the proof format. It is not legal advice, but it shows the kind of evidence bundle a lawyer, auditor, or support lead can review.

- Public certificate: certificate id, verification URL, hash, and integrity result.
- Consent snapshot: policy text, page URL, template versions, and acceptance context.
- Human-check receipt: a dual screen — Cloudflare Turnstile and an invisible proof-of-work (Cap/Altcha) — recorded as a verified verdict, not a checkbox.
- Origin forensics: the visitor's IP and full Cloudflare edge geolocation (country, region, city, postal, lat/long, EU flag, ASN), observed server-side so it can't be spoofed.
- Custody trail: timestamp, account ID, audit row, export metadata, and evidence payload hash.
- Export bundle: JSON/ZIP evidence for internal records, dispute response, or counsel review.
One company. Four proof products.
Start with the workflow you need today. The same account ID, billing, evidence vault, and verification language carry across the suite.
CapchaID
Owned login, sessions, users, email sign-in, Google sign-in, bot defense, 2FA-ready flows, custom auth domains, and enterprise identity options. Every signup mints a consent certificate with its origin and human-check evidence.
CapchaConsent Forms
One-line install for verified lead and consent capture. Dual human-check (Turnstile + invisible proof-of-work), origin forensics (IP + Cloudflare geo), consent snapshots, certificates, exports, and webhook/email delivery.
CapchaSign
Send PDFs for signature from your signed-in account. Completed envelopes produce sealed documents and completion certificates.
CapchaWallet
Consumer access to consent records with email verification, record lookup, revoke flows, and downloadable evidence.
The stack customers are buying

Install with one line.
Sign in, connect your website, and paste the generated install line into your site header or custom HTML area. The dashboard keeps the manual two-line embed available for exact placement control.
Normal users should not need to create OAuth apps, CAPTCHA keys, or API keys just to see value.
