CloakShare is an open-source (MIT) API for turning any document or video into a secure, tracked link with dynamic watermarks, email gates, and per-page analytics.

Built with Hono, Turso, Cloudflare R2. Self-hostable with Docker.

I built this because DocSend charges $45/user/mo and has no API. Happy to answer questions about the architecture.
