Papermark – the open-source DocSend alternative with custom domains
Hi HN! We’re Marc and Iuliia from Papermark (https://papermark.io). We're building an open-source, modern document sharing platform with real-time engagement analytics and 100% customization. It all started as a tweet [1] and led to our launch on Product Hunt [2] last month. We crossed over 1000 stars and over 10 contributors on GitHub (https://github.com/mfts/papermark). Incumbents, like DocSend, founded in the early 2010s have been acquired already and just don't innovate anymore. Their main priority is enterprise clients. As founders and developers ourselves…
In plain words
Papermark is an open-source document sharing platform designed for sending pitches, proposals, and other documents with real-time engagement analytics. Built as an alternative to DocSend, it offers custom domains, deep customization options, and integration capabilities. The platform is intended for founders, developers, and teams who need actionable insights into how recipients interact with their documents and want more control over their sharing infrastructure.

In the maker’s words, at launch
Hi HN! We’re Marc and Iuliia from Papermark (https://papermark.io). We're building an open-source, modern document sharing platform with real-time engagement analytics and 100% customization. It all started as a tweet [1] and led to our launch on Product Hunt [2] last month. We crossed over 1000 stars and over 10 contributors on GitHub (https://github.com/mfts/papermark). Incumbents, like DocSend, founded in the early 2010s have been acquired already and just don't innovate anymore. Their main priority is enterprise clients. As founders and developers ourselves we always felt that our needs are not being served. We struggle to get actionable insights when sending pitch decks to investors or sales proposals to customers. We are missing the flexibility and integrations with our existing applications and tech stack. That’s why we are building Papermark. Our bigger vision A developer-friendly document sharing platform doesn’t exist yet! We believe that document analytics should be available to anyone that is creating and sharing documents. - Rich observability: Don’t get left in the dark when sharing a document. Papermark will provide full transparency by exposing all document-related events through webhooks. - Fast performance: We are built on top of Vercel to serve your documents fast wherever your recipients are located and watching the engagement data arrive in real-time with Clickhouse under the hood. - Developer-friendly: We will be expanding the platform with a clean REST API, so you can create, share, connect and expand documents that you are sending both externally and internally. Let's stop sharing documents like it's 2013. I would love to hear your ideas, experiences, and feedback on any and all of the above. What issues have you had with document sharing?
