Loopback gives any local service a public HTTPS URL in one command — custom domains, automatic TLS, raw TCP, and a live request inspector. No deploys. No config.
Everything you need
Every tunnel gets a public *.tunnel.softwaller.in address with a valid TLS certificate — automatically.
Bring api.yourco.com, verify with one DNS record, and we provision and renew the certificate for you.
Replay and inspect every request in real time at 127.0.0.1:4040 — method, status, timing, headers, body.
Not just HTTP. Expose SSH, databases, gRPC or any TCP service with tunnel start --tcp.
Scoped API keys per agent, revocable anytime, plus allow/deny lists to restrict who can reach your tunnels.
Claim a stable name like acme.tunnel.softwaller.in so webhooks and integrations never break.
Three commands
Download the tunnel binary for your OS, or build from source.
$ curl -sSf loopback.sh | sh
Create an API key in the dashboard and log in once.
$ tunnel login --api-key <KEY>
Point it at a local port. Share the URL. Done.
$ tunnel start --port 3000
Built for the way you work
Point Stripe, GitHub, Twilio or Slack straight at your laptop — see every payload in the inspector.
Share a live, real-HTTPS URL of work-in-progress. No staging server, no deploy, no waiting.
Open your dev server on any phone or tablet, anywhere — not just the simulator on your machine.
Give a teammate temporary, IP-restricted access to your localhost — then revoke it in one click.
