Papermark IO

Papermark IO is an open-source platform for securely sharing documents and managing lightweight data rooms. It is designed as a practical alternative to DocSend, enabling users to distribute files through secure links while maintaining control over access, branding, and analytics. The primary purpose of Papermark IO is to streamline how teams share sensitive or important documents externally, such as pitch decks, contracts, or investor updates, while retaining detailed insight into viewer engagement.

Key features include customizable, branded document portals that align with your company identity, granular access controls, and detailed document tracking. Users can see who viewed a document, when they viewed it, and which pages they spent the most time on, helping teams understand interest levels and follow up more effectively. Papermark IO supports creating simple data rooms that bundle multiple documents under a single, trackable link, with options for password protection and expiration settings. As an open-source solution, it can be self-hosted or integrated into existing workflows, offering transparency and flexibility that proprietary tools may not provide.
