About DocKosha
DocKosha is an open-source document sharing and virtual data room application, with access controls, watermarking, and privacy-first analytics.
Inspect the DocKosha application and DocYantra engine on GitHub, or follow the self-hosting guide.
Secure Document Management for Professionals
DocKosha is built for M&A teams and founders running deal, investor, and diligence rooms. It also supports lawyers and fundraising teams sharing confidential packets with tighter controls than generic file links.
We focus on high-fidelity viewing and practical controls: watermarking, link permissions, and privacy-first analytics designed to minimize unnecessary data collection.
Our application source and DocYantra, our document-processing engine, are open source under AGPL-3.0-or-later for inspection, contribution, and self-hosting. DocKosha Cloud is available today, and you can self-host at your own risk without official support.
