Windows, macOS and Linux

KliemSoft runs where your business works: on Windows, on the Mac – with an Intel processor or Apple silicon – and as a server on Linux. Interface, features and data are the same on all systems. You choose an operating system, not a different application.

Windows

Desktop app for Windows 11 (64-bit) with installer. PRO server also as a Windows service.

macOS

Separate packages for Apple silicon (M1 to M4) and Intel Macs, macOS 13 Ventura or later, signed with an Apple Developer ID.

Linux

PRO server on Debian, Ubuntu and other distributions or in a Docker container. Operated in the browser.

Overview

Desktop app (Single)	Windows 11, x64	13 Ventura or later, Apple silicon and Intel	–
Desktop app as PRO workstation	yes	yes	–
PRO server	Windows 11 Pro, Windows Server, Docker Desktop	yes, as a background service	systemd service or Docker
Working in the browser (PRO)	yes	yes	yes – Firefox, Chrome

On Linux you use KliemSoft PRO: the server runs on your Linux system, and you work in the browser – on Linux, Windows, macOS or the iPad. There is no separate desktop app for Linux.

Windows

The installer sets up KliemSoft with a Start menu entry; you choose the installation folder yourself. Company files open with a double click. In the company network, the PRO server can also run as a Windows service.

macOS – Apple silicon and Intel

There is a matching package for every Mac: arm64 for Macs with an Apple chip (M1, M2, M3, M4) and x64 for Macs with an Intel processor. KliemSoft therefore runs natively on both architectures, without a translation layer. The app is signed with an Apple Developer ID.

Linux – the PRO server

KliemSoft PRO consists of the server with a PostgreSQL database and the workstations. On Linux, an installation script sets up the server as a systemd service, including a nightly backup. Alternatively, you start server and database with Docker Compose. Users work in the desktop app on Windows and macOS or directly in the browser.

The same on every platform

One license for all systems – the license is not tied to an operating system. You may use KliemSoft Single on up to three of your own devices, for example the Windows PC in the office and the MacBook on the road.
The same data – a company file created on Windows opens on the Mac and vice versa. When you upgrade to PRO, the server takes over all data, no matter on which system it was created.
The same interface – if you know KliemSoft on Windows, you will feel at home on the Mac and in the browser.
Same features, same updates – every version is released for all platforms at the same time.
Mixed teams – in PRO mode, Windows, Mac and browser workstations work with the same database at the same time.
