Tabby
FreeA modern, highly configurable terminal emulator with serial port support, SSH client, and extensive customization options.
What does this tool do?
Tabby is a cross-platform terminal emulator designed to replace the default terminal applications on Windows, macOS, and Linux. Unlike basic terminal emulators, Tabby integrates SSH client functionality with a connection manager, serial port terminal capabilities, and extensive customization options. It supports multiple shells simultaneously (PowerShell, WSL, Git-Bash, Cygwin, etc.), includes SFTP/Zmodem file transfer, X11 forwarding, and jump host configuration. The tool emphasizes developer workflow improvements through features like tab persistence, nested panes, progress indicators, and a built-in encrypted password manager. Tabby's architecture is plugin-extensible and theme-customizable via CSS, making it adaptable to individual preferences. It's open-source and distributed under FOSS licensing, with no apparent paywalls or commercial restrictions.

Pros & Cons
Advantages
- Genuine SSH integration with connection manager, jump hosts, and agent forwarding eliminates context-switching between terminal and SSH tools
- Built-in SFTP/Zmodem file transfer and X11 forwarding keep developers within one application for common remote workflows
- Encrypted password manager with master passphrase provides practical security for SSH credentials without relying on external tools
- Serial terminal with multiple connection profiles and hexdump mode is specialized functionality rarely found in general-purpose terminals
- Open-source and FOSS licensed with no paywalls, ensuring transparency and long-term availability
- Plugin-extensibility and CSS-based theming allow meaningful customization beyond simple color schemes
Limitations
- Learning curve for developers accustomed to traditional terminal emulators—the feature density could overwhelm casual users
- Plugin ecosystem appears underdeveloped compared to established alternatives like iTerm2 or Windows Terminal, limiting third-party extensions
- No mention of built-in package managers or shell plugin integrations (like oh-my-zsh or oh-my-posh), requiring manual configuration
- Reliance on single developer (Eugeny) for open-source project creates sustainability risk and potentially slower bug fixes
- Serial terminal features may be underutilized by general application developers, narrowing the appeal of this capability to specific hardware-focused users

Who is this for?
DevOps engineers, system administrators, embedded systems developers, and technical professionals who regularly use SSH, serial connections, or remote server management. Best suited for cross-platform teams (Windows/macOS/Linux) needing a unified terminal solution. Most valuable for power users who appreciate customization and developers requiring SSH functionality within their terminal rather than as a separate tool.
