Welly is a client for terminal BBS (Bulletin Board Systems), such as MITBBS, NewSMTH, PTT, and zixia BBS. It supports Telnet, SSH (Version 1 & 2), and WebSocket.

Welly is optimized for both Macs with Apple silicon and Intel-based Macs.

Compared with generic terminal emulators, Welly has many features specially designed for BBS.



  • You can browse the BBS using the mouse or the touchpad with gestures.
  • You can select and copy the text in normal mode or rectangle mode.
  • You can take a screenshot of the current page, or download articles in full text.
  • You can choose your color palette or use a transparent background.
  • You can customize fonts for English and Chinese separately.
  • Welly renders fonts smoothly and seamlessly for ASCII art.
  • Welly has anti-idle support so that you won't be logged out due to inactivity.
  • Welly supports macOS native full-screen mode and Dark Mode.
  • Welly supports the Touch Bar on the MacBook Pro.
  • Welly can show hidden texts, such as black text on a black background.
  • Welly can tell you where an IP address resides.


  • You can write articles in rich text, which supports colors, spell-checking, and undo/redo operations.
  • If you paste some rich text, Welly can automatically wrap long lines or convert the colors to ANSI escape sequences, so you don't have to memorize them.
  • Welly can warn you if you accidentally hit "paste" while not in the composing screen.
  • You can save and reuse your favorite emoticons.


  • You can preview images within Welly, which also shows the EXIF information.
  • You can open attachments and URLs using keyboard shortcuts.

In-BBS messaging

  • Welly notifies you about incoming messages in the macOS notification center.
  • Welly can automatically reply to messages while you are idle.


  • You can save your password or SSH private key for automatic login.
  • You can use HTTP, HTTPS, or SOCKS proxy servers.
