About zrok

zrok shares applications and resources from your machine through a zero-trust overlay network provided by OpenZiti. Public shares give a local service an internet-facing URL, which is handy for receiving webhooks, while private shares let other zrok users reach a resource without exposing it to any public endpoint.

Beyond HTTP proxying, it can share files and web content. Setup uses the commands zrok invite, zrok enable and zrok share. It is available as a hosted service from NetFoundry or can be self-hosted.

Strengths

  • Private sharing without exposing a public endpoint
  • Shares files and web content as well as HTTP services
  • Hosted or self-hosted

Limitations

  • Requires an invite and enabling an environment before sharing
  • Self-hosting involves running OpenZiti infrastructure
