Papermark
Open-source DocSend alternative for sharing documents and data rooms with built-in analytics
Papermark is an open-source DocSend alternative for sharing documents — pitch decks, sales collateral, data rooms — as trackable links instead of email attachments. You send a custom-branded link, and Papermark records who opened it, which pages they read, and how long they stayed, so a founder can see whether an investor actually finished the deck. It is MIT-era open source under AGPLv3, built in TypeScript on Next.js, with 8,755 GitHub stars as of June 2026 and a self-hostable or hosted option. But Papermark tracks engagement with a document; it doesn't create the demand to open it. The harder half is getting the right investors and buyers to that link in the first place, and writing the outreach that earns the open.
What Papermark is
Papermark (github.com/papermark/papermark) is an open-source platform for sharing documents as secure, trackable links rather than as files attached to an email. It sits in the same category as DocSend: you upload a pitch deck, a sales one-pager, or a folder of due-diligence files, share a link on your own custom domain, and Papermark logs the views. It is built in TypeScript on Next.js and Prisma, licensed AGPLv3, and can be self-hosted from the repo or used via the team's hosted plan.
- Trackable document links — share a deck or doc as a link, not an attachment, on your own branded domain.
- Page-level analytics — see who opened it, which pages they read, and how long they spent, so you know if an investor finished the deck.
- Virtual data rooms — bundle multiple files behind one link for fundraising or sales due diligence.
- Open-source + self-hostable (AGPLv3) — keep sensitive document data on infrastructure you control.
Where Papermark fits in a founder's growth stack
Papermark is a distribution and measurement layer for documents. For fundraising it tells you which investors actually engaged with your deck; for sales it shows whether a prospect read the proposal before going quiet. That signal is genuinely useful — a deck opened for nine seconds and a deck read to the last slide call for very different follow-ups, and most founders are guessing without it.
But a tracked link only reports activity once someone clicks it. The growth work happens upstream: building the investor list, writing the cold email that gets the intro, and earning the first wave of users whose traction makes the deck worth opening. See the playbook in how do I get my first 100 users and how do I write a cold email that gets replies.
What Papermark doesn't do — and what to pair it with
Papermark does not source your investor list, write your outreach, build your sales pipeline, or create the demand that makes a document worth reading. It is deliberately focused on one job: secure, measurable document sharing. To turn its analytics into raised rounds or closed deals you still need the execution that fills the top of the funnel.
| Papermark measures… | …the work that creates it |
|---|---|
| Whether an investor read the deck | the cold outreach and warm intros that put the deck in front of the right investor |
| Which proposal a prospect opened | the pipeline and follow-ups behind each deal |
| Engagement after a launch | the launch and PR push that earns the attention in the first place |

FAQ
- Is Papermark free?
- Papermark is open-source under the AGPLv3 license, so you can self-host it for free. The team also offers a hosted plan with a free tier and paid tiers for higher volume, custom domains, and data rooms. Check the repo and papermark.com for current limits.
- Is Papermark a good DocSend alternative?
- It targets the same core jobs — trackable document links, page-level analytics, custom domains, and data rooms — with the difference that it is open-source and self-hostable, which is the main reason teams pick it when they want to keep sensitive deck and deal data on their own infrastructure. Compare features against your needs at github.com/papermark/papermark.
- Will Papermark help me raise or sell faster?
- It helps you read the room — you learn who engaged and how deeply, so your follow-ups are better targeted. But it doesn't generate the investor or buyer interest itself. The bigger early bottleneck is getting qualified people to open the link, which is outreach, content, and launch work. See /roles/cold-email and /ask/how-do-i-get-my-first-100-users.
