What is Papermark?

What it is

Papermark open-source document-sharing alternative to DocSend. Project lives in Next.js/TypeScript web stack, category Business Software / Document Management & E-Signatures. GitHub metadata: 9166 stars, 1392 forks, 239 open issues, last push 2026-08-28T15:58:25Z. README says built-in analytics and custom domains. It is self-hosted, open-source, and customizable as needed. License field says NOASSERTION, so license terms need separate check.

It solves paid SaaS lock-in for secure document links: user hosts own app, uses own database, own blob storage, own email service, own analytics backend. It lets user send custom link for document, add own domain and branding, track document views.

Key capabilities

  • Share documents through custom secure links, with PDF and dataroom topics indicating document-centric use.
  • Add custom domain and branding to viewer-facing pages.
  • Gain insights through document tracking; page-by-page analytics listed as soon.
  • Self-hosted app built with Next.js, TypeScript, Tailwind, shadcn/ui, and Prisma.
  • Store app data in PostgreSQL through Prisma, authenticate through NextAuth.js.
  • Send email through Resend, process payments through Stripe, host through Vercel, store files in AWS S3 or Vercel Blob.

Who uses it and how

  • Teams replace DocSend for PDF and dataroom-style document sharing.
  • Self-hosters deploy Next.js app against PostgreSQL, S3 or Vercel Blob, Resend, Tinybird.
  • Developers customize viewer pages, data model, and self-hosted app using Next.js, TypeScript, Prisma, Tailwind, shadcn/ui.
  • Operators push Tinybird datasources and endpoints, then set TINYBIRD_TOKEN for analytics collection.
  • Users create shareable links, attach custom branding, and inspect document tracking data.

Getting started

Clone repo, npm install, copy .env.example to .env, run npm run dev:prisma, run npm run dev, open http://localhost:3000; prerequisites include Node.js version >= 18.17.0, PostgreSQL, AWS S3 or Vercel Blob, and Resend. Tinybird setup uses pipenv, Tinybird CLI, tb push datasources/, tb push endpoints/get_, and TINYBIRD_TOKEN; README also mentions Vercel hosting and contributing by fork plus pull request.

When to use it — and when not to

Use Papermark when DocSend replacement and self-hosted control matter. Avoid it when managed-only, no ops, or current page-by-page analytics required. Self-hoster must operate PostgreSQL, blob storage, Resend email, Tinybird analytics, and Node.js app; Stripe and Vercel also appear in stack. Facts show weakness: page-by-page analytics soon, contributors 0, 239 open issues, repo age 0 years, license NOASSERTION. README lists clone/npm path and Vercel hosting, not Docker image names or hosted option.
