What is tuiport?

Tuiport is a starter project for building interactive terminal applications that users connect to over SSH, with everything hosted on Cloudflare's infrastructure. SSH is the same protocol you use to log into a remote server from a command line. Instead of a web page with buttons and forms, users open a terminal and type a command like "ssh hostname" to reach an interface that looks like a text-based app. The interface itself is built with a library called OpenTUI, which handles drawing text, colors, and interactive elements inside a terminal window. Tuiport wires OpenTUI together with an SSH server running inside a Cloudflare Container (a way to run small isolated programs on Cloudflare's network). Because Cloudflare's system does not yet support accepting direct incoming TCP connections to containers, the project also includes a small relay component written in Go. That relay sits on any machine with a public address, receives the SSH connection from the user, and forwards the encrypted bytes over a WebSocket connection to the Cloudflare side. The relay cannot read the SSH session contents, it only converts the connection type. There is also a browser-based version of the same terminal application embedded in a landing page. This lets visitors try the interface in a regular web browser without needing SSH, though it is intentionally limited: no shell access, no command execution, no filesystem. Deploying the project is handled by a setup script that logs you into Cloudflare, deploys the Worker and Container, generates the required secrets automatically, and stores them without you needing to paste anything into a web form. A one-click deploy button is also available for the site and browser demo portion, with SSH enabled in a follow-up step. The project is described as a proof-of-concept at version 0.0.1. It is aimed at developers who want to build shared terminal interfaces for both humans and AI agents. The code is open source under the MIT license.
