### Introduction

Welcome to OpenSign, the premier open-source docusign alternative - document e-signing solution designed to provide a secure, reliable, and free alternative to commercial platforms like DocuSign, PandaDoc, SignNow, Adobe Sign, Smartwaiver, SignRequest, HelloSign & Zoho sign. Developed under the OpenSignLabs organization, our mission is to democratize the e-signing process, making it accessible and straightforward for everyone.

### Features

- **Secure PDF E-Signing:** With the help of Robust encryption algorithms, OpenSign™ ensures maximum security, privacy & compatibility.
- **Annotate Documents:** OpenSign™ allows you to annotate PDF documents with an advanced signing pad that comes with hand drawn signatures support as well as uploaded images & saved signatures for the simplest signing experience.
- **User-Friendly Interface:** OpenSign™ was built while keeping Intuitive design in mind for ease of use. Features like "Sign yourself", "One click signatures" and "OpenSign Drive" makes it stand out of the crowd and even makes it better than a lot of so-called industry leaders.
- **Multi-signer Support:** OpenSign's ability to invite multiple signers for signing along with the ability to invite witnesses & being able to enforce signing in a sequence makes it the only open source solution that is fully loaded and allows it to compete head-to-head with established players.
- **Email Unique Code(OTP) verification support for guest signers:** With OpenSign™, your documents are fully secure even when being signed by guest users. Guest signers can only sign the document after entering a unique code sent to their email address. 
- **"Expiring Docs" & "Rejection":** You can set documents to expire after certain number of days after which nobody will be able to sign it. Not just this, OpenSign also allows signers to reject signing a document.
- **Beautiful email templates:** All document signing invitations, completion notifications & reminders are formatted using great looking email templates.
- **PDF Template Creation(coming soon):** OpenSign™ allows you to create and store PDF document templates for repeated use thereby saving you a lot of time.
- **OpenSign™ Drive:** It is a centralised secure vault for your signed documents that makes storing, signing, organizing, sharing & achieving your docs a breeze.
- **Audit Trails & completion certificate:** Being a security focused solution, OpenSign™ makes it a top priority to save detailed logs for tracking document activities along with time-stamps, IP addresses, email IDs & phone numbers. A completion certificate is generated as soon as document is completed which contains all the document related logs for added safety.
- **API Support(coming soon):** OpenSign™ API allows seamless integration into existing systems and software. APIs will soon be available as a cloud hosted solution.
- **Integrations:** Seamless integrations with various Cloud storage systems, CRMs & enterprise platforms is coming soon.
