Self-hosted e-signatures. First document free, then $149 once for unlimited envelopes.

Every install can create and fully complete one envelope free — send it, collect all signatures, download the flattened PDF with its certificate page. Creating a second envelope asks for a $149 lifetime license key (sold on Whop). One payment, unlimited documents forever.

Yes — the full source is MIT-licensed at github.com/bensblueprints/inkseal-mvp and always will be. The $149 buys the license key plus the signed Windows installer, 1-click setup and updates instead of running git clone yourself.

Inkseal implements the core requirements commonly associated with ESIGN/UETA (US) and basic eIDAS "simple electronic signature" validity: demonstrated intent via click-to-sign, consent capture (completion is refused without the "I agree to sign electronically" checkbox), association of the signature with the record, a tamper-evident hash-chained audit trail, and copies for all parties. It is NOT a Qualified Electronic Signature (eIDAS QES) — no certificate-based digital signatures, no Qualified Trust Service Provider, no KBA identity verification, and no compliance certification is claimed. That's fine for everyday agreements like leases, contracts and NDAs; legal sufficiency depends on jurisdiction and document type, so if you need QES or work in a regulated industry, consult a lawyer first. Full details on the Inkseal compliance page.

Every event (created, sent, viewed, consented, each field signed, completed, declined) records the UTC timestamp, signer email, IP and user agent, chained with sha256(prev_hash + event) and rooted in the SHA-256 of the original uploaded PDF; the final PDF's SHA-256 is recorded at completion. Anyone can hit Verify and recompute the whole chain — no need to take a vendor's word for it. DocuSign's certificate is solid too, but it's proprietary; you trust them, not math you can check.

No. Each signer gets a unique link, signs in the browser, and that's it. You need SMTP configured to email invitations automatically — or just copy the links and send them however you like.

No QES, no in-person notarization features, and no big integration marketplace — DocuSign genuinely wins on ecosystem breadth and compliance certifications. Inkseal covers the upload-place-route-sign-verify workflow that most freelancers, landlords and small teams actually use.
