zrok - Secure Sharing

Share local services via secure tunnels using a self-hosted zrok instance.

Quick Reference

Public Sharing

Expose a local service with a public HTTPS URL:

# Share a web server
zrok share public http://localhost:3000
# Returns: https://xyz123.z.spamt.net

# Share a directory as file server
zrok share public --backend-mode web /path/to/files

# Share with reserved name (persistent URL)
zrok reserve public http://localhost:3000 --unique-name myapp
zrok share reserved myapp
# Always: https://myapp.z.spamt.net

Private Sharing

Share only with other zrok users (end-to-end encrypted):

# Machine A - share
zrok share private http://localhost:3000
# Returns token: abc123xyz

# Machine B - access  
zrok access private abc123xyz
# Creates: http://127.0.0.1:9191 -> Machine A's localhost:3000
