Secure remote support, on your terms
KoolAssist connects two computers for fast, secure remote support — end-to-end encrypted, self-hosted, and never routed through a third-party cloud. One download, no accounts to create.
Windows · macOS · Linux · self-hosted — never a third-party cloud
Why KoolAssist
The convenience of remote support, without handing your screen to a third-party cloud you don't control.
End-to-end encrypted
Every session is encrypted end to end. The relay only ever moves ciphertext — the content of your screen is never readable in transit.
Self-hosted & private
Runs on dedicated, self-hosted infrastructure. Your sessions never traverse a third-party remote-access cloud.
You're in control
A session only ever starts when the person at the keyboard shares their ID and one-time password. Consent-based access — never silent, never a surprise.
Every platform
Native clients for Windows, macOS (Intel & Apple Silicon) and Linux. One download, open, and you're connected.
How it works
No accounts, no setup. Three steps from download to fixed.
Download & open
Grab the client for your platform and run it — nothing to install for a one-time session.
Share your ID
Share the ID and one-time password shown on your screen with the person helping you.
Connect & fix
They connect over the encrypted link, with your consent, and sort it out while you watch.
Privacy you can actually verify
We built KoolAssist so the honest answer to "what can anyone in the middle see?" is a short one.
- ✓No one in the middle can see your screen.Sessions are end-to-end encrypted; even the relay that connects the call only handles ciphertext.
- ✓Only connection metadata is kept, never content.Who connected and when — for security and quality. Screen contents and files are never stored.
- ✓Recording is off by default.A session is only ever recorded if it's explicitly turned on.
- ✓Your data stays in your jurisdiction.Self-hosted — no handing your sessions to a foreign remote-access cloud you don't control.
