Rutba Sign
Coming soonElectronic signature software
The signature is the easy part. The evidence is the product.
Anyone can put a picture of a signature on a page. What decides a dispute two years later is whether you can still show what happened: who opened it, from where, what disclosure they accepted, in what order, and that not one byte has moved since. Rutba Sign records that ceremony as it happens, hash-chains it so it cannot be reordered or thinned, and seals it — and the counterparty can verify the result without an account, without trusting us, and without paying anything.

Not released yet. The engine is built and running, and you still cannot buy this on its own. Those two facts sit together because what is missing is not the product: it is card capture and pooled hosting, so today Sign runs for organizations that already hold a Rutba licence. Two more pieces are outstanding and worth knowing before you compare us to anyone: visible signature marks drawn on the pages of the original PDF, and the identity-verification and qualified-certificate partners that European qualified signatures require. Two things are already decided and worth knowing now: visible marks on the pages of an uploaded PDF arrive after the evidence record does, because a signature is made valid by the record rather than by the picture; and a customer who stops paying keeps every completed envelope and its evidence, permanently. Verification stays public and free for the same reason.
Who it's for
- Businesses sending contracts, quotes and engagement letters for signature
- Anyone who needs a signed agreement to hold up later, not just look signed
- Teams tired of paying per seat for a product their clients use once
What you get
- Signing by link — your counterparty needs no Rutba account
- An append-only, hash-chained record of the whole ceremony
- Identity evidence you choose per signer: email, phone code, access code, location
- A certificate of completion that never claims more than was actually verified
- Documents pinned by hash on arrival and never rewritten
- Ordered, parallel or mixed signing, with approvers and cc parties
- Public verification that works without an account or a subscription

What ships with Rutba Sign
Each is a full application in its own right, sharing the same records as the rest.
Sign
Early accessCompose an envelope — documents, parties, signing order, fields, expiry — then track it and collect the sealed result.
Built and running on a licensed instance: the composer, tracking, the ceremony and public verification. Visible signature marks placed on the pages of the original PDF are the piece still to come.
Signing engine
Available nowThe envelope, the append-only evidence ledger, and the seal over the completion manifest.
Built and green, with the evidence ledger, the seal, an RFC 3161 timestamp from a public authority and the platform countersignature. Around 110 automated checks stand behind it, including both tamper directions.
Verify
Available nowThe public check: present a completed package, get valid, tampered or unknown. No account, and free forever.
Live, and free forever: a counterparty checks a completed package without an account, without a subscription and without trusting us.
Some of these are not finished, and they are labelled. You are not charged for an app you cannot open — the plans below switch on what ships, and anything marked here arrives on your existing plan when it lands.
