Download Narrowlink

Narrowlink is a free, open-source self-hosted solution for securely exposing services and devices behind NAT or firewalls to the internet without port forwarding or VPN configuration. It uses a lightweight agent-gateway architecture that makes it easy to connect to remote machines, share local services, and tunnel traffic securely.

Unlike traditional VPN solutions, Narrowlink requires no changes to your firewall or router. You deploy a gateway server on a VPS or cloud host, install agents on the devices you want to access, and then connect to those devices through the gateway using simple CLI commands or a web browser.

Narrowlink supports TCP and UDP tunneling, HTTP/HTTPS reverse proxying, and WebSocket forwarding. It is written in Rust for performance and safety, and can be deployed via Docker for easy setup. It is ideal for developers who need to expose development servers, manage remote machines, or share services without complex infrastructure.
