## What it is
ttyd is a simple command-line tool written in C that shares a terminal session over the web using WebSockets and an xterm.js-based browser frontend. It supports SSL, basic authentication, file transfer (ZMODEM/trzsz), Sixel images, and runs on macOS, Linux, BSD, OpenWrt, and Windows.

## Use cases
- access a remote terminal from a browser
- share a shell session over the web
- run a web-based terminal on a router with OpenWrt
- give students browser access to a Linux shell
- debug an embedded device terminal remotely
- expose a CLI tool through a web interface

## When to choose
- you need browser-based access to a terminal without SSH client setup
- you want a lightweight, fast, cross-platform terminal sharing tool
- you need terminal access on resource-constrained devices like OpenWrt routers
- you want built-in SSL and basic auth for terminal sharing

## When to avoid
- you need multi-user session management or recording (use a full bastion/SSH solution)
- you require fine-grained authorization beyond basic auth
- exposing a raw shell to untrusted networks without additional hardening
