E-signature, but independently verifiable
CapchaSign vs DocuSign
DocuSign is the market standard, and for good reason. CapchaSign is e-signature built on a different foundation: a completed document carries a tamper-evident seal a third party can verify themselves — recompute the hash, check the signature against our published public key — plus video-of-signing evidence, bring-your-own payment processor so we never touch your money, at per-record cost instead of per-envelope caps.
Where CapchaSign is genuinely different
- A seal anyone can verify, not just us. Every completed envelope is Ed25519-signed and dual-anchored (an RFC 3161 timestamp authority and Bitcoin via OpenTimestamps). A skeptic — an auditor, opposing counsel — can independently recompute the document hash and check the signature against our published key. DocuSign's audit trail is authoritative because you trust DocuSign; ours is checkable without trusting anyone.
- Video-of-signing evidence. Optionally capture a short video at the moment of signing, bound into the same sealed record. DocuSign has no equivalent.
- Bring-your-own payment processor. Collect payment at signing through your own Stripe, PayPal, Adyen, or Square account — you are the merchant of record and CapchaCloud structurally never touches the funds (it fails closed rather than routing through a platform key). DocuSign Payments runs through DocuSign's own Stripe relationship.
- Per-record cost, no envelope caps. No 100-envelopes-per-year ceilings, no per-envelope overage tiers to track. A completed envelope is 100 credits (≈$0.50), video-of-signing is a 40-credit (≈$0.20) add-on — no seats, no caps.
- One platform. The same evidence layer powers your auth, your lead-consent capture, and your signatures — one bill, one verifiable chain, not three vendors.

When DocuSign is the better pick
We believe in honest comparisons. If your deal or regulator requires a completed SOC 2 Type 2 report, an eIDAS qualified signature, a licensed 21 CFR Part 11 module, or the reassurance of a signature format with years of federal case-law behind it, DocuSign holds that ground today and we will tell you so. Those are audit-and-track-record moats, not feature gaps — and pretending otherwise would undercut the one thing we are selling: verifiable honesty. CapchaSign is the right call when you want a signature whose integrity a third party can check for themselves, video and payment evidence in the same sealed record, and pricing that doesn't cap you by envelope.
