Features
Everything you need to ship from localhost
A focused toolkit for getting local code onto the public internet—and understanding exactly what happens next.
Persistent domains
Reserve memorable URLs like my-app.opts.ink that stay yours across restarts and redeploys.
Request inspection
See every request and response in real time—headers, body, status, and latency—straight from the dashboard.
Webhook debugging
Point Stripe, GitHub, or any provider at your tunnel and replay deliveries until the integration is right.
One-command setup
A single static binary. No accounts to wire up, no router config, no ngrok-style session limits.
Secure by default
Automatic TLS on every domain, with token-based access controls so only the right people connect.
Instant replay
Resend any captured request with one click to reproduce bugs without triggering the source again.
How it works
Live in under a minute
Three commands from a fresh terminal to a live, inspectable public URL.
Install OpenTunnel
Run the installer on macOS or Linux.
Authenticate the CLI
Sign in once and your machine is linked to your workspace.
Go live
Point a persistent public domain at your local server.
Traffic inspector
Inspect every request as it happens
Every request through your tunnel is captured with full headers, payloads, status codes, and timing. Filter by method or status, dig into a single call, and replay it instantly to reproduce the exact conditions that broke your code.
- Real-time streaming of requests and responses
- One-click replay without hitting the source again
- Works with any framework, port, or webhook provider
