Localtunnel is an HTTP tunneling service that exposes local development servers to the public internet. By creating secure tunnels with temporary public URLs, it allows developers to route incoming internet traffic directly to a web server running on a local machine.
The service provides predictable or custom subdomains to facilitate remote collaboration and testing of local applications. It functions as a localhost proxy server, enabling users to receive and inspect external webhook payloads directly within a local environment during the development lifecycle.
The platform manages traffic through secure tunnels, ensuring that data is encrypted between the public internet and the local development server. It includes capabilities for monitoring tunnel activity, such as tracking incoming requests and connection status, to maintain visibility into the health of active sessions.
The project is available as a command-line utility and provides an API for integrating tunnel management into development workflows.
