Lets you e-sign a document by forwarding it via email, using your provider's DKIM signature as proof instead of a signing company; open source, self-hosted or hosted, pay-per-document.
Watch out · The provider states it never holds a signing key and can't forge or alter documents — that's the product's own security claim, not independently audited.
No sign-upWorks offlineOpen source
What to know▼
How it works
Forward a document to the service and type 'I sign this document' — your email provider's existing DKIM signature becomes the proof of signing, bundled into one self-contained file anyone can verify offline in a browser.
What's different
No third-party signing company is trusted with the signature — the proof relies entirely on infrastructure (DKIM) that already exists and would still verify even if this service disappeared.
Pricing
4 free signatures, then $0.25 per document, no subscription. Open source (Apache-2.0) — self-host or use the hosted version.
Best for
People who need a lightweight, verifiable e-signature for occasional documents without paying for a full e-signature platform subscription.
Watch out
The provider states it never holds a signing key and can't forge or alter documents — that's the product's own security claim, not independently audited.
