Documents and notes decision
DocuSign
A competent developer can build a narrow e-signature workflow (send, sign, store, audit) in a week and self-host it, but you’ll lose DocuSign’s certifications, global scale, advanced identity and multi-channel delivery, and broad integrations—key enterprise value that’s expensive to replicate.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All DocuSign alternatives, with the arithmetic →
What a replacement has to do
- Upload document, define signers & signature fields, send envelope for signatures, collect signature events (webhooks), store signed document and audit trail.
What it still won’t have
- FedRAMP, ISO, and other enterprise compliance certifications out of the box
- Global scale and uptime guarantees for millions of users
- 1000+ pre-built third-party integrations and App Center ecosystem
- Advanced identity verification and managed notarization features
- Multi-channel delivery (WhatsApp/SMS) add-ons and vendor-managed messaging
What remains hard
- Compliance and regulation
Docusign meets the most stringent global security standards.
- Infrastructure at scale
1 billion people and 1.8 million customers use Docusign

Runnable build prompt
Build a minimal self-hosted eSignature service using Node.js (Express), PostgreSQL, and S3-compatible storage. Implement: (1) upload and store PDFs; (2) a simple UI to place signature fields and save templates; (3) send signing invitations via SMTP (and optional Twilio SMS) with unique expiring signer links; (4) signer flow that captures signatures (draw/typed) and embeds them into the PDF, producing a signed PDF; (5) webhook/event processing to record an auditable trail (timestamps, signer email/IP) in Postgres; (6) REST API to create/send envelopes and to fetch envelope status. Out of scope: advanced identity verification, legal/compliance certifications, WhatsApp delivery, enterprise SSO. Include error handling, input validation, retries for outbound messages, and unit + integration tests for upload, send, webhook, and download flows.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
