ScriptCommunicator / serial terminal
Scriptable data terminal which supports several interfaces.
ScriptCommunicator is a scriptable cross-platform data terminal that supports serial port (RS232, USB to serial), UDP, TCP client/server, SPI, I2C, and CAN. All sent and received data can be shown in a console and can be logged in an html and a text log. In addition to the simple sending and receiving of data, ScriptCommunicator has a JavaScript interface. This script interface has the following features: - Scripts can send and receive data with the main interface. - In addition to the main interface scripts can create and use their own interfaces (serial port (RS232, USB to serial), UDP, TCP client, TCP server, PCAN, and SPI/I2C). - Scripts can use their own GUI (GUI files which have been created with QtDesigner (is included) or QtCreator). - Multiple plot windows can be created by scripts (QCustomPlot developed by Emanuel Eichhammer is used) -

Cmder
Portable console emulator for Windows
Cmder is a lovely portable console emulator package for Windows. It was built out of sheer frustration due to the lack of nice console emulators on Windows. It is based on the amazing ConEmu, with major config overhaul, enhancements from Clink, Monokai color scheme and a custom prompt layout. Overall, it's got a very pleasant user interface that's much improved from ConEmu. The biggest advantage with cmder is that it is portable. It was designed to be totally self-contained, totally free of external dependencies. This makes it perfect for USB Sticks or cloud storage, so you can have your settings, aliases, binaries and history wherever you go. -

ConEmu - Handy Console Window
Local Terminal Emulator
ConEmu-Maximus5 aims to be handy, comprehensive, fast and reliable terminal window where you may host any console application developed either for WinAPI (cmd, powershell, far) or Unix PTY (cygwin, msys, wsl bash). As Windows console window enhancement (local terminal emulator), it presents multiple consoles and simple GUI applications as one customizable tabbed GUI window with various features. Also, due to deep integration, ConEmu is the best companion for Far Manager, my favorite shell replacement. Disclaimer. ConEmu is not a shell, so it does not provide "shell features" like tab-completion, command history and others. But you can run any shell or remote access client of your choice in ConEmu! Try Clink for bash-style completion in cmd.exe and PSReadLine or PowerTab in powershell.exe. Or just run Bash from your favourite distro. Also, ConEmu does not provide remote access (SSH/Telnet/...) too, just use your remote client (ssh.exe, telnet.exe) instead. -

cool-retro-term
A good looking terminal emulator which mimics the old cathode display
cool-retro-term is a terminal emulator which mimics the look and feel of the old cathode tube screens. It has been designed to be eye-candy, customizable, and reasonably lightweight. It uses the QML port of qtermwidget (Konsole). This terminal emulator works under Linux and macOS and requires Qt 5.2 or higher. Settings such as colors, fonts, and effects can be accessed via context menu. Just grab the latest AppImage from the release page and make it executable and run it. Make sure to install the dependencies first. Once you installed all dependencies (Qt is installed and in your path) you need to compile and run the application. Also, before the building process, remember to install Xcode and agree to the licence agreement. -

ConEmu
Customizable Windows terminal with tabs, splits, quake-style, etc.
ConEmu-Maximus5 aims to be handy, comprehensive, fast and reliable terminal window where you may host any console application developed either for WinAPI (cmd, powershell, far) or Unix PTY (cygwin, msys, wsl bash). As Windows console window enhancement (local terminal emulator), ConEmu presents multiple consoles and simple GUI applications (like PuTTY for example) as one customizable tabbed GUI window with various features. Moreover, due to deep integration, ConEmu is the best companion for Far Manager. ConEmu is not a shell, so it does not provide "shell features" like remote access, tab-completion, command history and others. ConEmu is an advanced console window where you can run any shell of your choice. However, some of these features have been placed in the RoadMap. You may also try Clink for bash-style completion in cmd.exe and PSReadLine or PowerTab in powershell.exe. You can easily run old DOS applications (games) in Windows 7 or 64-bit OS. -

wslbridge2
Explore various ways to connect Windows Subsystem
wslbridge2 is a Windows Subsystem for Linux bridge that connects WSL environments with Windows terminal emulators. It is designed for users who want a better terminal experience than the default console while still running Linux shells inside WSL. The project explores multiple connection methods between Windows, WSL, Cygwin, MSYS2, and terminal frontends. It is especially associated with mintty-based workflows, where a Windows terminal needs a reliable backend path into WSL. wslbridge2 handles the technical handoff between the Windows-side terminal process and the Linux-side shell session. Its main value is making WSL feel more integrated with traditional Unix-style terminal tools on Windows. -

SSHTOOLS
Java SSH API
This project now hosts the third-generation of Java SSH API, Maverick Synergy. This API builds on the Maverick Legacy commercial APIs and delivers a new API in a unified client/server framework. This API is available to the community under the LGPL open source license. This update includes ed25519 support, support for the new OpenSSH private key file format and stronger key exchange algorithms. The project continues to host both the original API and legacy applications created around it, however, these are now considered deprecated and we do not recommend their use in anyway. -

Intelligent Terminal
A fork of Windows Terminal with native agent integration
Intelligent Terminal is a free, open-source Windows Terminal fork that integrates AI coding agents directly into the command-line environment. It preserves familiar terminal features such as tabs, profiles, themes, and keyboard shortcuts. A docked agent pane provides contextual assistance using output from PowerShell, Bash, and WSL sessions. Users can connect GitHub Copilot, Claude, Codex, Gemini, and other compatible agents. The software detects command failures and can request AI-generated troubleshooting suggestions. Proposed commands require user approval before execution. Its agent management interface tracks active sessions, task states, and token consumption. Intelligent Terminal also supports custom model providers and dedicated agent profiles. It requires Windows 10 version 2004 or newer. -
