tunnelto.dev

tunnelto.dev is a tunneling service that creates public URLs for your local web servers. It lets you expose applications running on localhost to the internet through secure, temporary URLs. This means you can share your work-in-progress web apps, APIs, or static sites with colleagues, clients, or testers without deploying to a production environment.

The tool works by installing a lightweight client on your machine that establishes a secure tunnel between your local server and tunnelto.dev's public endpoints. You get a custom subdomain (like mydemoapp.tunnelto.dev) that routes traffic directly to your local environment. What makes it stand out is its simplicity - just run a single command with your desired port and subdomain, and you're immediately live. The open-source nature means developers can inspect the code or even self-host the tunneling service if needed.

This tool is particularly valuable for developers who need to demo applications, test webhook integrations with services like Slack or Stripe, or develop mobile apps that require connection to local backend servers. Instead of dealing with complex deployment processes or network configuration, developers can focus on building and testing their applications with real-world access scenarios.
