## What it is
OpenSign is a free, open-source document e-signing application and DocuSign alternative built with React, Node.js, and MongoDB. It supports secure PDF signing, annotations, templates, completion certificates, an API, and self-hosting.

## Use cases
- sign pdf documents electronically
- self-host a docusign alternative
- send documents for e-signature
- create reusable signing templates
- get completion certificates for signed contracts
- integrate e-signature via API
- sign ndas and contracts online

## When to choose
- you need a free or self-hosted DocuSign alternative with full data control
- you want unlimited e-signatures without per-document pricing
- you need an API to embed signing into your own workflows

## When to avoid
- you need legally certified signatures for jurisdictions requiring specific qualified signature standards
- you want a lightweight CLI or library rather than a full web application
- you cannot run Node.js and MongoDB infrastructure
