Everything you need to run tunnels in dev, CI and demos. Below is a quick peek; the full site will include guides, API schemas and troubleshooting.

Quickstart
ssh -p 443 -R0:127.0.0.1:3000 x@xpos.to
  • Opens a reverse tunnel
  • Auto-assigns a public subdomain
  • Proxies to your local port
CLI Reference 
Flags:
  -R <rem:host:port>  Remote port map
  -p 443               Connect via TLS port
  -N                    No remote cmd (tunnel only)
Env:
  XPOS_TOKEN           Auth token
  XPOS_PORT            Local port override
Auth & Security
  • SSH transport with strong ciphers
  • Per-session isolation
  • Optional token binding via XPOS_TOKEN
Custom Domains
  • Reserve subdomain prefixes
  • Bring your own apex via CNAME
  • Auto TLS with DNS-01
Example: Laravel @ 8000
$ php artisan serve --host=127.0.0.1 --port=8000
$ ssh -p 443 -R0:127.0.0.1:8000 x@xpos.to
> Allocated: https://calm-owl.xpos.to
> Forwarding & TLS active. Ctrl+C to close.

Frequently Asked Questions

Answers to common questions about security, limits, and usage

Yes. Tunnels run over SSH with end-to-end encryption; no plaintext data is exposed.

Any TCP service. The CLI auto-detects common dev ports (3000, 5173, 8000, 8080) and prompts on conflicts.

No. Your machine initiates the SSH connection out to port 443. As long as you can reach the Internet on 443, you’re good.

Reserved subdomains are part of paid tiers. Free tier auto-assigns memorable names on each session.

Yes. The CLI is non-interactive and supports environment variables for tokens and ports. Ideal for ephemeral preview URLs.

A generous free tier is planned for personal and demo use. Paid tiers unlock custom domains, longer sessions, and priority routing.

Press Ctrl+C in the terminal that started the tunnel. The session ends and the URL is reclaimed.

Yes. Public URLs are served over HTTPS with valid TLS certificates automatically managed by the edge.
