zrok is an open source sharing solution that leverages OpenZiti, a programmable zero-trust network overlay, to enable instant and secure resource sharing. Available as both a managed SaaS service and self-hosted deployment, zrok simplifies secure sharing with just three commands: zrok invite, zrok enable, and zrok share.

Unlike traditional HTTP proxies, zrok provides private sharing where resources remain unexposed to public endpoints, with all communication securely transported between clients through the zero-trust overlay network. The platform extends beyond simple HTTP proxying to support decentralized resource sharing of files, repositories, video content, and other resource types through a flexible peer-to-peer framework.

Key capabilities include:

Zero-trust security built on OpenZiti for effortless protection
Flexible deployment options from Raspberry Pi to enterprise-scale infrastructure
Private and public sharing modes for different use cases
Single binary deployment containing everything needed to operate zrok environments
Rapid setup enabling users to start sharing within minutes

The platform is designed to scale both up for large service instances and down for minimal deployments, making it suitable for organizations of any size. Being free and open source, zrok eliminates friction from secure sharing workflows while maintaining enterprise-grade security through its zero-trust foundation.
