## What it is
Butterfly is a browser-based terminal emulator built on websockets and the Tornado web framework, compatible with xterm. It supports multiple simultaneous sessions, theming, SSL/X509 and PAM authentication, and can run as a systemd socket-activated daemon.

## Use cases
- access a shell from a browser remotely
- run a terminal in a web page
- share a terminal session across multiple devices
- self-host a web-based ssh-like terminal
- view terminal output with desktop notifications

## When to choose
- you need terminal access from any device with a browser
- you want multiple clients attached to the same session
- you need SSL certificate or PAM-based authentication for remote shells

## When to avoid
- you need an actively maintained project - the last release was 2020
- you only need a local terminal emulator
- you prefer a modern alternative like ttyd or wetty

## Facets
