PuTTY launched in 1999 and it shows. AidaIDE bundles tabbed SSH, integrated SFTP, serial console, file editing, fleet management, and AI assistance — all in one window. Windows today, with macOS and Linux builds in progress.
AidaIDE vs PuTTY in short: PuTTY is a ~1 MB portable SSH terminal and nothing else — no tabs, no file transfer, no stored passwords. AidaIDE adds tabbed sessions, a dual-pane SFTP browser on that same session, edit-in-place remote files, and an AES-256 credential vault, free forever. Keep PuTTY when you need a portable binary.

PuTTY is great software. It's free, lightweight, and has earned its place as the default SSH client for two decades. If you open a terminal once a week to ping a server, PuTTY is fine — keep using it.
This page is for the other case. The case where your workflow looks like: PuTTY for SSH, WinSCP for SFTP, separate window for serial, Notepad++ for quick edits, a spreadsheet of device IPs, and ChatGPT in a browser tab when something breaks. That's six tools doing one job.
AidaIDE consolidates them into one workspace — free forever for SSH, SFTP, vault, and fleet. Optional Pro ($19/mo) adds the AI suite when you want it. Whether that upgrade is worth it depends on how often you switch windows.
What you get out of the box with each tool. PuTTY ratings reflect the official PuTTY release, not third-party forks like KiTTY or SuperPuTTY.
| Feature | AidaIDE | PuTTY |
|---|---|---|
| SSH / SSH2 | ✓ Full support | ✓ Full support |
| Telnet / Rlogin / Raw | ✓ | ✓ |
| Serial console (COM ports) | ✓ Built-in Auto-detect baud, logging, side-by-side with SSH | ✓ Separate window per session |
| Tabbed sessions | ✓ Native SSH, SFTP, serial all in one window | ✗ Each session opens a new window. SuperPuTTY/MTPuTTY add tabs externally. |
| SFTP / file transfer UI | ✓ Built-in dual-pane SFTP | ~ PSFTP & PSCP are command-line only; most users install WinSCP separately. |
| Remote file editor | ✓ Syntax highlighting for 30+ languages, edit in place | ✗ No file editor — download, edit elsewhere, upload back |
| Multi-device fleet management | ✓ Fleet manager with grouping, tagging, OTA update push | ✗ Session profiles only — no fleet view |
| Credential vault | ✓ Encrypted credential store with master password | ~ Saved sessions store passwords in registry (not encrypted) |
| AI assistance in terminal | ✓ Multi-agent AI Hierarchy Code generation, command explanation, debugging | ✗ |
| Industrial protocols (Modbus, SCADA) | ✓ Built-in support | ✗ |
| Security scanner for connected devices | ✓ | ✗ |
| Windows / macOS / Linux | ✓ All three, first-class | ~ Windows native; Mac/Linux ports exist but lag |
| Open source | ✗ Closed source, commercial | ✓ MIT license |
| Price | Free forever Pro (AI suite) $19/mo or $190/yr · 5-year price lock on annual | Free |
Not "PuTTY is bad" — it's that the workflow PuTTY enables hasn't kept up with how modern embedded development actually works.
Stop alt-tabbing between PuTTY, WinSCP, a serial terminal, your editor, and a notes app. SSH, SFTP, serial, and the file editor all live in the same workspace — tab between them like browser tabs.
If you manage more than five devices, PuTTY's flat session list breaks down. AidaIDE groups devices by project, tags them by role, and shows status across the fleet — push an OTA update to "all Raspberry Pis tagged 'prod'" in one click.
"What does this kernel panic mean?" "Write a systemd service for this script." "Why is my ESP32 dropping wifi?" The AI Agent Hierarchy is in the same window as your sessions — no copy-paste to a browser.
You won't lose anything. Here's how the migration goes.
No conflict — they coexist. Try AidaIDE for a week without giving up your PuTTY sessions.
AidaIDE reads PuTTY's session profiles from the Windows registry on first launch. Your hosts, ports, and key paths come across automatically.
Drag your .ppk or OpenSSH keys into the credential vault. They're encrypted with a master password and unlocked once per session.
Or don't. Most users uninstall PuTTY within two weeks once they're used to tabs. But the choice is yours.
.ppk private keys work?.ppk format directly, plus standard OpenSSH keys. No conversion needed.Install alongside PuTTY, import your sessions, and see if it sticks. The SSH workspace is free forever — Pro is optional at $19/mo or $190/yr with a 5-year price lock on annual.
