PuTTY or Bitvise SSH Client? It depends on your day
Both are mature Windows SSH clients and both are free to use. They differ in scope: one is a focused terminal, the other is a workstation for remote access. Here is how that plays out in practice.
Footprint and startup
PuTTY is a single executable that opens instantly and runs from a USB stick with no installer. The Bitvise client installs properly, starts a little slower, and gives you more in return once it is open.
File transfer
PuTTY ships PSFTP and PSCP, both command-line. Bitvise includes a dual-pane graphical window with a queue and resume. If you move files daily, this difference outweighs everything else on the list.
Tunneling and reconnect
- PuTTY: local, remote and dynamic forwarding, configured per session.
- Bitvise: the same, plus one-click Remote Desktop tunneling and a SOCKS proxy.
- Bitvise reconnects automatically after a dropped link; PuTTY does not.
Who should pick what
- Occasional console access on many different PCs — PuTTY.
- Daily remote administration with file work — Bitvise SSH Client.
- Locked-down machines where you cannot install software — PuTTY portable.
- Teams that want vendor support behind the tool — Bitvise.
