Introduction
What JustTunnel is and when to use it.
JustTunnel exposes a local HTTP server to the internet via a public HTTPS URL. Open a port on your laptop, run one command, and share that port as a URL anyone can hit — no firewall changes, no DNS, no deploy.
When to use it
- Receive a webhook from Stripe, GitHub, Twilio, or anything else that needs to POST to a public URL while you build locally.
- Show a work-in-progress to a client, designer, or teammate without spinning up staging.
- Test a mobile app, smart-home device, or another machine against the API running on your laptop.
- Reproduce a bug that only happens when traffic comes in from outside your network.
- Run a quick demo from a coffee shop without deploying.
When not to use it
- Production hosting. A tunnel is bound to a process on your machine. If your laptop sleeps, the URL goes down. Deploy real apps to a real host.
- Always-on services that need 99.99% uptime. Worker tunnels keep a connection alive across reboots, but the underlying machine is still yours to babysit.
- Static IP requirements on both ends. If you need a fixed identity for your client too, a VPN like Tailscale or WireGuard is a better fit.
- Hosting binary-large content (multi-GB downloads). Free and Pro plans have bandwidth caps — see Plans & limits.
