VNC and RDP in one app
VNC with Raw, CopyRect, ZRLE and Tight encodings, and RDP with NLA sign-in and pinned TLS certificates.
Native VNC & RDP remote desktop client
Connect to any VNC or RDP machine — including a Mac's built-in Screen Sharing — from one small, fast native app. No browser tab, no Electron.
Everything you need, nothing you don't
Works with a Mac's Screen Sharing
Sign in with your Mac username and password — no extra software needed on the Mac.
Fast on slow links
Colour depth adapts to your connection and only changed pixels are drawn, so even long-distance sessions stay usable.
Many sessions at once
Keep several machines open and switch instantly. Dropped connections reconnect on their own.
Stay organized
Colour tags, quick connect, and import or export of your saved connections.
Private by design
Passwords live in your OS keychain, never in a config file.
Clipboard and keys
Two-way clipboard sync, full keyboard passthrough and a Ctrl+Alt+Del button.
Speaks your language
38 languages, including right-to-left scripts, picked automatically.
