whoami.filippo.io
A ssh server that knows who you are. $ ssh whoami.filippo.io
whoami.filippo.io powers a diagnostic service that reports what your client and connection look like from the other side, making it a handy mirror for network and TLS debugging. It surfaces details such as your IP address, protocol versions, cipher suites, SNI, and other attributes that are otherwise tedious to confirm across layers. The tool emphasizes clarity and minimalism, helping engineers quickly verify configuration changes in browsers, proxies, VPNs, or CLI tools. It is especially helpful when validating modern TLS features like ALPN, HTTP versions, and certificate behavior under different client stacks. Because the output is human-friendly, it doubles as an educational resource for understanding how transport and application-layer negotiations actually manifest. Teams use it to troubleshoot misconfigurations and confirm policy enforcement without setting up their own inspection endpoints. -

HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate patches We also support Ubuntu packages. Add them to your package manager with `sudo add-apt-repository ppa:rapier1/hpnssh` Fedora RPMs can be added with, `sudo dnf copr enable rapier1/hpnssh`

Russh
Rust SSH client & server library
Russh provides a Rust library for implementing SSH clients and servers with a modern, async-friendly design. It exposes building blocks for authentication, channel management, port forwarding, and key handling, allowing you to embed SSH functionality directly into Rust applications. The API is designed to be explicit and composable, making it possible to implement custom behaviors like reverse tunnels, interactive shells, and service multiplexing. Because performance and safety are central, the code leverages Rust’s type system to reduce classes of runtime errors common in network protocol implementations. The project also includes examples and discussion threads that show how other tools integrate it for web-based clients or gateway services. For teams building terminals, proxies, or embedded management planes, it offers a robust foundation without shelling out to external binaries. -

Tabby Web
An SSH/Telnet/Serial client in your browser
Tabby Web brings a modern terminal experience to the browser by pairing a web UI with a backend gateway that brokers TCP connections over WebSockets. It aims to deliver an experience similar to the desktop Tabby terminal—sessions, profiles, and rich configuration—while being accessible anywhere through a login. The architecture splits concerns: a Django-based control plane manages users, auth, and configuration, while a gateway service handles network transport so browser clients can reach SSH, Telnet, or serial targets. This separation enables multi-user deployments with persistent settings, role-based access, and storage backends for artifacts. It’s useful for organizations that need managed remote access from within a web portal, without installing a full desktop client on every machine. With its focus on admin ergonomics and end-user UX, Tabby Web turns terminal access into a managed, auditable, and scalable web application. -

ssh-chat
Chat over SSH
ssh-chat is a custom SSH server written in Go that allows you to chat over SSH connection. When you open your terminal and type in a command, instead of getting a shell you get a chat prompt. With ssh-chat you get a simple chat room over a secure shell connection, where you can send and receive private messages, check any user's public key fingerprint for identification purposes, and more. You can change the color theme of the chat, block or kick users, and chat on just about any platform where an SSH client is available, including on mobile. -

http-proxy-tunnel
Create nested tunnels through HTTP proxies
Http-proxy-tunnel creates TCP tunnels through http proxies that permit the CONNECT method. It differs from other proxy tunnelling programs in that it can tunnel through multiple proxies, and can use SSL tunnels. These abilities mean that in combination with a web server that can proxy (such as Apache) you can serve normal web pages from ports 80 and 443 and connect to the server (using ssh say) via those ports at the same time. All available documentation can be read online at http://http-proxy-tunnel.sourceforge.net/ -

Self-Healing Ind. File Transfer (Shift)
Fast reliable local/remote file transfers, sync, tar create/extract
Shift is a lightweight framework for high performance local and remote file transfers that provides resiliency across a wide variety of failure scenarios through various techniques. These include end-to-end integrity via cryptographic hashes, throttling of transfers to prevent resource exhaustion, balancing transfers across resources based on load and availability, and parallelization of transfers across multiple source and destination hosts for increased redundancy and performance. -
