Terminal Manager

One terminal to rule them all. Every remote session in one streamlined Windows app, with a built-in AI assistant, Python automation and an embedded server stack. Replaces PuTTY, WinSCP — and half your toolbox.

The headline feature

An AI that speaks CLI

Paste nothing. Switch nowhere. The assistant reads your live terminal, understands the device you’re connected to — Cisco, Juniper, RAD and more — and acts only with your permission.

🔍
Diagnose

“Why is this BGP neighbor down?” — it reads the session output and tells you, with the exact show commands it ran.

📖
Explain

Highlight any wall of output and get a plain-English explanation, on your screen, in seconds.

⚙️
Generate & configure

Describe the change; it plans the commands, shows a preview, and a safety risk-gate asks before anything mutating runs.

🔒
Private if you want

Run it against a 100% local model (Ollama, LM Studio, vLLM) — nothing ever leaves your machine.

Major feature|Clients

Every protocol,
one window

Ten connection types under one roof — so the console cable, the jump host, the firewall's web UI and the file transfer all live in the same app, sharing the same favourites, the same logging and the same shortcuts.

🧰
Retire the toolbox

One app instead of PuTTY, WinSCP, Tera Term, an RDP client and a browser tab — no more hunting for the window that holds the session you need.

📂
Favourites that scale

Folders, live search, drag-and-drop organising, and a greyed-out icon the moment a COM port disappears. Right-click to ping, duplicate or open a parallel SFTP session.

🚀
Connect the way you like

Quick-Connect (Ctrl+Shift+Q) for one-line access, saved favourites for the fleet, or auto-start so critical sessions are open before you sit down.

🔒
Safe by default

SSH host keys pinned on first use to catch a man-in-the-middle, and every credential encrypted at rest with Windows DPAPI — never in plain text.

YTS Terminal Manager clients panel — saved connections in folders with search, alongside a live Windows Shell session YTS Terminal Manager new connection dialog — picking a type from SSH, Telnet, Serial, SFTP, FTP, SCP, RDP, Windows Shell or CMD YTS Terminal Manager SFTP client — dual-pane file transfer between the local PC and a remote server
Remote shells
SSHTelnetSerial

Routers, switches, firewalls and embedded gear — over the network or straight down an RS-232 / RS-485 console cable.

File transfer
SFTPFTPSCP

Drag files onto a session to upload, or browse the remote tree in a sidecar panel that follows your shell's directory.

Desktop & web
RDPWeb

Remote desktops and device management UIs open as ordinary tabs — no leaving the app to reach a web console.

Local shells
PowerShellCMD

Full ConPTY terminals that run modern TUIs properly — launch them with preset arguments and startup commands.

Major feature|Embedded servers

Six servers,
already installed

The services you normally scramble to install mid-job are already here, one click from the session that needs them. Start a TFTP server, push the firmware, stop it — without ever leaving the app or touching a separate download.

YTS Terminal Manager servers panel — SFTP, FTP, TFTP, TACACS+, SYSLOG and Terminal Server with live counters
The stack · six services, grouped and started with one click
YTS Terminal Manager SFTP server view — live transfers, throughput, and a filterable structured event log
SFTP live · transfers, throughput and a searchable event log — not a text file
YTS Terminal Manager Terminal Server — COM port to TCP mappings over SSH and Telnet with a shareable link
Terminal server · local COM ports, reachable over SSH or Telnet
File transfer
SFTP · 22FTP · 21TFTP · UDP 69

Serve a config backup or firmware image to a device in seconds. Replaces tftpd64 and FileZilla Server — no install, no firewall dance.

Authentication & logging
TACACS+ · TCP 49SYSLOG · UDP 514

Test AAA against a real TACACS+ server, and catch a device's syslog the moment it misbehaves — with auth counts and rejects on screen.

Console access
Terminal ServerSerial-over-IP

Share your local COM ports over SSH or Telnet — a console server in software, with a copy-link to hand a colleague. No hardware to buy.

📊 Structured live log viewers 🔎 Filter, search & inspect events ⚡ Start only what you need 🧹 Nothing extra to install
Major feature|Detachable tabs

Multi-screen

Drag any tab straight out of the main window and it becomes a real, standalone window — drop it on your second screen and keep that one critical session in view while you work everywhere else. The connection never drops on the way over.

Major feature|Multi-view

Multi-view layout

One window, four ways to look at it — single, horizontal, vertical and matrix. Focus on one device, split the window into panes, or tile the whole fleet and watch every session react at once. Switch layout any time; nothing disconnects.

YTS Terminal Manager single view — one session filling the window, the rest waiting in tabs
Single · one session, full window — the rest wait in tabs
YTS Terminal Manager horizontal view — two live sessions side by side in one window
Horizontal · two sessions side by side — compare output as you work
YTS Terminal Manager vertical view — two live sessions stacked one above the other
Vertical · sessions stacked — ideal for wide, long output
YTS Terminal Manager matrix view — four sessions tiled in a grid
Matrix · every session tiled — the whole fleet at a glance
Major feature|Tools

The diagnostics,
built in

The questions you ask on every callout — is it up, what's open, where does the path break, what's this OID — answered from the same window as the session. No hunting for a separate utility, no pasting IPs between apps.

YTS Terminal Manager tools panel — IP/port scanner results alongside SNMP walk, ping, traceroute, Wake-on-LAN, subnet calculator and network interfaces
IP / port scanner · sweep a subnet, sort by state, inspect any row — with the whole toolbox one click away
YTS Terminal Manager network monitor — latency history graph tracking up to ten hosts with loss and min/max/average statistics
Ping latency · up to ten hosts on one timeline — loss, min/max/avg, and the spike you're hunting
Live tools · stateful
IP / Port ScannerSNMP Walk

Sweep a subnet for reachable hosts and open ports with accurate open/filtered classification, or walk a device's OID tree — results in sortable, exportable report views.

Utilities · one-shot
Ping latencyTracerouteWake-on-LANSubnet calc

Watch ten hosts at once on a live graph, trace where a path breaks, wake a sleeping machine, or work out a prefix — IPv4 and IPv6 both.

Local inspection
Network interfaces

Your own adapters, IP/MAC addresses and routing table at a glance — and a jump straight into Windows' adapter properties when you need to change one.

Major feature|Python API

Automate it,
don't retype it

A real Python interpreter wired to your live sessions. Read the screen, send commands, drive SFTP, even automate an embedded web page — scripted once, then run against one device or the whole fleet.

Run against the active tab

Point a script at whichever session is in front, or at a specific one. Output lands in the console beside the editor — no context switch, no copy-paste.

📑
A real editor

Multiple script tabs, syntax highlighting, a snippet library and a formatter — so the thing you wrote last quarter is still readable today.

🌐
Terminals and web

The same API drives an embedded web tab: navigate, read the page, fill fields, click, run JavaScript — for the device UIs that never got a CLI.

🚀
Fires on connect

Attach a script to a favourite and it runs the moment the session opens — health checks, logins and collection done before you look at the screen.

FAQ

Questions, answered

Is YTS Terminal Manager really free?
Yes. Completely free for Windows — no license key, no registration, no trial expiry, no ads, no bundled software. Download the installer and use every feature, forever.
Is it a good PuTTY alternative?
It covers everything PuTTY does (SSH, Telnet, Serial) and adds tabbed multi-session views, SFTP/FTP/SCP transfers, RDP, an AI assistant, Python automation, command broadcast and an embedded server stack — features that would otherwise need PuTTY + WinSCP + several more tools.
Which AI models does the assistant support?
Anthropic Claude, OpenAI, Google Gemini, Qwen, GLM and GitHub Models — or a fully local model via Ollama, LM Studio or vLLM for air-gapped environments. You bring your own API key; a free Gemini key works out of the box, and the assistant is entirely optional.
Can it act as a console server for serial devices?
Yes. The Terminal Server feature bridges local COM ports to the network over Telnet or SSH, with per-port authentication — a software console server built in.
Is my data safe?
Favourites and credentials are encrypted at rest with a per-install key sealed by Windows DPAPI. SSH host keys are pinned on first use (TOFU) to detect man-in-the-middle attacks, and the AI risk-gate asks before any risky command runs.
What are the system requirements?
Windows 10 or Windows 11 (64-bit), 4 GB of RAM minimum and about 600 MB of disk space. No additional runtimes needed.
