Generate the document, send it for signature, and get a court-grade audit trail back — one API, one bill. The developer-first alternative to DocuSign.

A clean, hosted signing page keeps your signers focused — with consent, intent, and identity captured on every signature.
Store a template once with {{placeholders}}, then send only the data that changes. We render a pixel-perfect PDF, hash it with SHA-256, and attach it to the envelope.
DocumentationThis agreement is made on {{date}}, between {{company}} and {{employee}}, for the role of {{role}}.
The employee agrees to the terms set out herein and signs below.
Every envelope ships with a tamper-evident certificate of completion — consent, intent, IP addresses, timestamps, and the document hash — sealed with a PAdES signature and an RFC 3161 timestamp when configured.
No per-seat pricing, no sales call. Test mode is free and unlimited; volume bundles lower the rate.
Build and test the entire flow.
Pay per envelope. Generation included.
Volume, SLA, and AES/QES on the roadmap.
Signed is a developer-first e-signature API that also generates the document for you. With one API call you generate a document from a template or HTML, send it to one or more signers, collect a legally binding electronic signature, and get back the sealed PDF plus a court-grade audit trail.
Signed is $0.15 per envelope with document generation included, and volume bundles lower the rate. Test mode is free and unlimited, with no per-seat pricing and no sales call.
Yes. Signed implements Simple Electronic Signatures (SES) under US ESIGN and UETA and EU eIDAS. Every envelope captures consent and intent, authenticates the signer, and ships with a tamper-evident, hash-chained audit trail sealed with a PAdES signature, plus an RFC 3161 timestamp when configured.
Signed is built for developers: a clean API and SDK you embed in your own product, transparent $0.15-per-envelope pricing with no envelope caps, and document generation built in. DocuSign is enterprise-sales-gated with per-seat pricing and was not designed for embedding.
Signed supports the United States and the European Union — covering ESIGN and UETA in the US and eIDAS SES in the EU.
Yes. Send a stored template plus data, raw HTML, or a file URL, and Signed renders a pixel-perfect PDF, hashes it with SHA-256, and attaches it to the envelope — so you never need a separate document-generation vendor.
Grab a test key, send an envelope to yourself, and watch the signed copy and audit trail land in your dashboard.
