Good to know.

What’s included for free?

Max access through December 31, 2027: up to 30 tunnels, reserved subdomains, and custom domains. The local HTTP inspector shows headers and captured bodies up to 64KB. No card required.

How do I use a reserved subdomain?

Reserve an available name in your workspace, then run teztun http 3000 --subdomain myapp. Replace myapp with your reserved name. Using your own domain?

Does my computer need to stay on?

Yes. Your app and TezTun must stay running. Visitors see an offline page when your HTTP tunnel is unavailable.

Can I connect more than web apps?

Yes—APIs, WebSockets, static sites, and MCP servers. Databases and other non-HTTP services use a TCP tunnel with an assigned IP and port. Explore the guides.
