Expose

Expose is an open source tunneling service that allows developers to securely share locally running web applications with the public internet through temporary public URLs. The project functions as an alternative to tools like ngrok by creating encrypted tunnels that route incoming requests from a publicly accessible server directly to a developer’s local machine. This makes it possible to test webhooks, demonstrate applications, or collaborate with teammates without deploying the project to a staging server. Expose is written in PHP and can be self-hosted, giving developers full control over their infrastructure, domains, and traffic while avoiding reliance on third-party tunneling services. The system includes both a client and server component, where the client runs locally and the server manages incoming connections and tunnel routing. It can bypass common restrictions such as firewalls or VPN limitations by establishing an outbound connection from the local machine to the tunnel s
