Sign

Free e-signatures. Sealed, hashed, provable.

We needed to send a real agreement and refused to pay DocuSign for the privilege — so we built our own on our own infrastructure, then opened it to everyone. Free, with a stronger evidence trail than the tools that charge for one.

sign.blacklabeltec.com

Send a document for signature in the next sixty seconds.

Name and email gets you sending — no card, no trial, no sales call. Your counterparty taps a link, consents, and signs from any phone. The completed PDF comes back with the certificate and hashes already inside it.

What you get

Everything the paid tools charge for.

Certificate of completion

Consent, timestamps, IP, and device for every signer — burned into the final PDF itself, not parked in a vendor's cloud you'll lose access to.

Tamper-evident hashes

The original and signed SHA-256 are recorded on a public verification page. Anyone holding a copy can prove it's untouched, forever.

Sequential routing

Up to eight signers, in order. Each gets a private link that activates only when it's their turn. Counterparties need no account.

Actually free

Three envelopes a day, free forever. No trial clock, no per-envelope fees, no watermark ransom. We built it because we were done renting signatures.

How it works

Three steps, no manual.

01

Upload & place

Drop in a PDF and click where signatures, initials, dates, and checkboxes go.

02

Share the links

Each signer gets a private signing link — send it by text, email, or Slack. However you already talk.

03

Sealed & delivered

Signers consent (ESIGN/UETA) and sign by drawing or typing. Everyone gets the sealed PDF and its verification page.

The honest part

What it doesn't do yet.

Templates, reminders, decline-to-sign, CC viewers, and parallel routing are being built in public — same as everything else on this site. What ships is verified end-to-end before it's listed here; nothing on this page is a roadmap wearing a product's clothes. U.S. ESIGN/UETA compliant; it is not an EU qualified-signature product.

This is what we build for clients.

BL Sign went from zero to production on our own stack in a day. If your business needs its own tools — apps, platforms, automation — that's the work we sell.
