Cairn Rooms
A data room is secure document sharing with control and tracking — link-level permissions, page analytics, watermarking, due-diligence rooms. Cairn Rooms gives you that as software you own, from a tracked share link to a full deal room, hosted by you.

Every way to get data rooms.
We’d rather you saw the whole map than a sales pitch. Here are the tools teams actually evaluate — what each is good at, said plainly. Cairn is one option among them.
Commercial
Hosted, polished, rented — your data lives on their cloud.Open source
Self-hostable and yours to run — read each license closely.So why Cairn?
DocSend made tracked sharing effortless; iDeals and Datasite run the heavy M&A end — all of them hosting your most sensitive documents on their cloud, priced from per-link to enterprise. Open-source here is genuinely thin: Papermark is the one purpose-built option. Cairn Rooms gives you tracked sharing and data rooms as code you own — confidential documents on your own infrastructure, extensible by your own agents.
However you get there, Cairn Rooms is software you own — full source in your GitHub repository, running in your own cloud. No phone-home, no license server, no kill switch. Export your data any time; Cairn could disappear tomorrow and your software would keep working.
