What it really is

Tabby — a free, open-source, cross-platform terminal emulator with built-in SSH, Telnet, and serial client.

Our take

The DB has this tool badly mislabeled: Tabby Terminal is not a POS payment system — it is a highly configurable, MIT-licensed terminal emulator (formerly 'Terminus') for Windows, macOS, and Linux, available at tabby.sh. DB pricing of $20/mo and the retailer/café description are entirely incorrect; the tool is completely free and squarely developer-facing. With 72k+ GitHub stars, split panes, persistent tabs, an integrated SSH/SFTP/Telnet client, and a growing plugin ecosystem, it is one of the most popular modern terminal replacements available.

Why we rate it

72k+ GitHub stars and 200+ releases signal a mature, actively maintained project. The breadth of built-in protocols (SSH, Telnet, serial) plus community plugins makes it exceptionally capable for a zero-cost tool.

The catch

No official commercial support — users rely on GitHub Issues and community forums. The plugin API is powerful but documentation is sparse, and some advanced configurations have a steep learning curve.

Best for
Developers replacing PuTTY or native OS terminals with a feature-rich alternative
Sysadmins managing multiple SSH connections with persistent profiles and split panes
Power users wanting deep theming, plugin extensions, and cross-platform consistency
Not good for
Non-technical users who need a GUI-only workflow with no command-line exposure
Teams requiring enterprise support SLAs or centralized fleet management
Mobile or browser-only environments (desktop install required)
Friction report
Time to value
Fast: download, install, and open a local or SSH session in under 5 minutes; no account or signup required.
Scale breakpoint
No hard scale limit as an OSS tool, but managing dozens of SSH profiles and config-sync across machines requires manual setup or community plugins.
Walled garden
Low: MIT license means full portability; config files are local and human-readable; no vendor lock-in.
