ngrok Node.js wrapper
Expose your localhost to the web. Node wrapper for ngrok
ngrok is a Node.js wrapper for the ngrok tunneling client, allowing developers to expose local services to the internet directly from JavaScript or the command line. It is commonly used for webhook testing, local API demos, development previews, and temporary public access to local applications. The package can start HTTP, TCP, and TLS tunnels, with options for ports, regions, authentication tokens, basic authentication, custom configuration paths, and logging callbacks. It also exposes a wrapper around ngrok’s local client API, letting applications list tunnels, start or stop tunnels, inspect requests, replay requests, and clear request history. The module can be installed locally for application-level use or globally for CLI-style tunneling. Overall, it gives Node.js projects a convenient programmable interface for managing ngrok sessions. -

nodejs-argo
nodejs-argo is a powerful Argo tunnel deployment tool
nodejs-argo is a Node.js-based deployment tool for creating Argo tunnel proxy nodes on PaaS and lightweight hosting platforms. It is built for environments where users want a simple package-based setup using npm, npx, or direct Node.js files. The project supports several proxy protocols, including VLESS, VMess, and Trojan, making it flexible for different proxy client configurations. It can run with temporary tunnels when no fixed Argo credentials are provided, or with fixed tunnel settings when domain and authentication values are configured. The tool also integrates optional Nezha monitoring, which helps users track node status from a separate panel. Its configuration is mainly driven through environment variables, making it convenient for container, PaaS, and background service deployments. -

oSKY
Framework implementing SS7 over IP & SIGTRAN interworking and trunking
oSKY (OpenSKY) is a full communication framework to implement PSoTN (Public Social Telephony Network). In contrast with PSTN (Public Switched Telephony Network), oSKY intends to implement an open paradigm in the internet domain, gaining more than 100 years of experience from traditional telephone network. oSKY goals: -enhanced security (SSL, SCTP) -embedded NAT tunneling -Global title discovering on Internet style -Peer2Peer mode and Gateway mode -more to come ... oSKY project drivers: - drastically reduce bandwidth usage by performing smart lookup of enum numbering space. avoiding PSTN outbound trunking when not necessary and linking IPPABXs in the internet domain with failover capabilities. -

pgrok
HTTP/TCP reverse tunnel solution through SSH remote port forwarding
The pgrok is a multi-tenant HTTP/TCP reverse tunnel solution through remote port forwarding from the SSH protocol. This is intended for small teams that need to expose the local development environment to the public internet, and you need to bring your own domain name and SSO provider. It gives a stable subdomain for every user and gated by your SSO through the OIDC protocol. Think of this as a bare-bones alternative to the ngrok's $65/user/month enterprise tier. Trying to put this behind a production system will blow up your SLA. For individuals and production systems, just buy ngrok, it is still my favorite. -

piko
An open-source alternative to Ngrok, designed to serve production
Piko is an open-source reverse proxy and tunneling system designed as a self-hostable alternative to ngrok. It lets upstream services open outbound-only connections to Piko, then routes incoming traffic back through those established tunnels. This design is useful for services that are private, behind NAT, firewalled, or otherwise not publicly routable. Piko is built for production-oriented hosting rather than only short-lived development demos. It supports a server and agent model, with the agent running near the upstream service and forwarding traffic from named endpoints to local ports. The project also includes Kubernetes-oriented deployment guidance, clustering behavior, and a single binary that can run in both server and agent modes. -

py-multiaddr
multiaddr implementation in Python
py-multiaddr is a multiaddr implementation in Python. Every choice in computing has a tradeoff. This includes formats, algorithms, encodings, and so on. And even with a great deal of planning, decisions may lead to breaking changes down the road, or to solutions that are no longer optimal. Allowing systems to evolve and grow is important. The Multiformats Project is a collection of protocols that aim to future-proof systems, today. They do this mainly by enhancing format values with self-description. This allows interoperability, and protocol agility, and helps us avoid lock-in. -

rock_s_architecture
Universal CORBA architecture, split your software
Predefined CORBA architecture to develop software into two parts : the real computer kernel (server) and the exploitation or UI part (client). Sources are independant of the CORBA distribution (MICO, omniORB, ORBacus, TAO, Visibroker) and are fully portable. JAVA Servlets for HTTP tunneling. The Server is in C++ and the Client in C++ and JAVA.Very usefull in real time projects. This is a small sample to be adapted to your project. -

scrapy-proxy-headers
Handle custom proxy headers when making HTTPS requests in scrapy
The scrapy-proxy-headers package is designed for adding proxy headers to HTTPS requests in Scrapy. In normal usage, custom headers put in request.headers cannot be read by a proxy when you make a HTTPS request, because the headers are encrypted and passed through the proxy tunnel, along with the rest of the request body. You can read more about this at Proxy Server Requests over HTTPS. Because Scrapy does not have a good way to pass custom headers to a proxy when you make HTTPS requests, we at ProxyMesh made this extension to support our customers that use Scrapy and want to use custom headers to control our proxy behavior. But this extension can work for handling custom headers through any proxy. -

sshh allows you to make a persistent tcp connection (tunnel) over an http proxy. Once you have it set up, you can make new connections from either end. Similar in concept to httptunnel but more versatile and scalable.

subnet
Simple, auditable & elegant VPN, built with TLS mutual authentication
subnet is a simple VPN client and server project designed to make private networking more approachable. It focuses on creating an auditable VPN implementation rather than a large enterprise networking platform. The project provides both server and client behavior, allowing users to connect machines through a managed private network path. Its README notes that the project works, but also warns that it has not received thorough review and may hit performance limits above roughly 100 Mbps. Because of that, it is better understood as an educational or experimental VPN project than a first choice for production infrastructure. Its value comes from its readable design, minimalism, and focus on helping users understand VPN behavior without excessive complexity. -

xkcptun
xkcptun is kcp tunnel for OpenWRT&LEDE, implemented in c language
xkcptun is a C-language implementation of kcptun built on KCP and libevent2. It is mainly designed for embedded and router-oriented environments such as LEDE and OpenWrt, where lightweight networking tools are often preferred. The project provides client and server components that use KCP-based tunneling to improve performance over unreliable or high-latency network links. It also includes a spy utility, making the generated build more than a minimal two-binary tunnel setup. xkcptun can be built with CMake and supports static linking for easier deployment on constrained systems. It is most relevant to users who need a compact KCP tunnel implementation for routers, gateways, and custom network appliances. -

zoro
zoro can help you expose local server to external network
Zoro is a Go-based tunneling tool for exposing local services to an external network. It supports TCP and UDP forwarding, which makes it useful for HTTP, HTTPS, SSH, DNS, and other network services. The project follows a simple client-and-server model where the remote server opens an external port and forwards traffic back to a local service. It also includes HTTPS-specific server and client modes that can map local HTTP services to subdomains under a configured domain. Zoro is designed around minimal configuration, making it practical when users need a quick way to publish a private service without a full reverse proxy stack. Its main value is straightforward local-to-public service exposure across different protocol types.
