Termphin vs PuTTY

PuTTY is the free SSH and Telnet client a generation of admins grew up on, for Windows and Unix. There is no official mobile version. Termphin does the same job on your phone, and its shell keeps running on the server when the connection drops.

Which one is for you

Pick Termphin if you want

  • Your phone

    Termphin is built for a touchscreen: a key toolbar for Ctrl, Esc and arrows, snippets and swipeable tabs.

  • Sessions that survive

    Termphin's open-source agent keeps the shell running when your phone loses signal.

  • Files in a browser

    An SFTP browser with a code editor instead of PSFTP commands.

Pick PuTTY if you want

  • On a desktop

    PuTTY is the standard on Windows, with Pageant and Plink for scripting.

  • Telnet and serial

    For old kit and console cables, PuTTY still covers it.

  • Fully open source

    MIT licensed and maintained since 1999.

Bringing your PuTTY setup

  1. Convert your key

    In PuTTYgen, load your .ppk and use Conversions, Export OpenSSH key.

  2. Import it

    Move the exported file to your phone and import it in Termphin's key manager.

  3. Add your sessions

    Each saved PuTTY session becomes a profile with address, user and key.
