Portr

Portr is an open-source, self-hosted tunneling platform for exposing local HTTP, TCP, or WebSocket services to the public internet. It uses SSH remote port forwarding under the hood, which gives it a familiar and secure transport foundation. The project is designed for teams that need an ngrok-like workflow while keeping control of their own infrastructure. It includes both server and client components, along with a dashboard-oriented experience for managing tunnel usage. Portr can help developers test webhooks, share local applications, expose APIs, or temporarily publish development services without deploying them permanently. Its main purpose is to provide a practical self-hosted tunnel service that balances developer convenience with infrastructure ownership.
