## What it is
Extraterm is an open-source terminal emulator with modern workflow features like shell integration that frames command output, a built-in SSH client, image display, and a command palette. It is written in TypeScript and available in a Qt-based version (0.60+) and a legacy Electron-based version.

## Use cases
- terminal emulator with shell integration to frame command output
- ssh client that works on windows
- reuse previous command output as input for new commands
- view images inside the terminal
- keyboard-driven terminal with a command palette
- easy file uploads and downloads over ssh without extra tools
- highlight errors and warnings in terminal output

## When to choose
- you want a feature-rich terminal beyond plain teletype emulation
- you work across Linux, macOS, and Windows including WSL
- you frequently reuse command output in follow-up commands
- you want built-in ssh and file transfer without extra tools

## When to avoid
- you need a minimal, ultra-lightweight terminal
- you require only the 1.0-stable software - it is pre-1.0 with occasional bugs
- you rely on features only present in the deprecated Electron version

## Facets
- artifact type: application
