Why Netcatty
If you regularly work with a fleet of servers, Netcatty is built for speed and flow:
Netcatty is applying to the SignPath Foundation open-source program. Once
approved, covered Windows release artifacts will use Free code signing provided by SignPath.io, certificate by SignPath Foundation.
See the code signing policy and
privacy policy. Windows releases may remain unsigned until the
application and integration are complete.
> Windows portable data: Exit Netcatty, then create a folder named data beside Netcatty.exe (zip build) or beside the portable launcher. Netcatty will store its profile there on the next launch. Saved passwords and private keys remain protected by the Windows user account that created them, so they must be re-entered after moving the folder to another computer or Windows account.
> Open folders in Netcatty on Windows: The installed version adds Open in Netcatty to Explorer's folder context menu and folder-background context menu. It opens a local terminal in that folder. On Windows 11, choose Show more options first. Turn the menu off or on in Settings โ System โ Windows Explorer. ZIP and portable versions do not add this menu by default.
> macOS Users: Current releases are expected to be code-signed and notarized. If Gatekeeper still warns, make sure you downloaded the latest official build from GitHub Releases.
Nix / NixOS
Netcatty provides a flake that wraps the official Linux AppImage release for Nix and NixOS users:
nix run github:binaricat/Netcatty
For declarative installs, add the Netcatty flake as an input and use inputs.netcatty.packages.${pkgs.system}.default in your NixOS or Home Manager package list.
