ARM CPU

HCL has shown working prototype of Domino 14.5.1 running on a Raspberry Pi with an ARM CPU at Engage 2026

Officially published versions of HCL Domino are not compiled for ARM CPU’s and will not work on the following hardware

• Raspberry Pi
• Intel Atom CPU’s
• Amazon EC2 Graviton
• Apple Silicon (M1/M2/M3/M4/M5 CPU’s)

There are several AHA ideas out there - please vote for them if you want HCL Domino to be supporting ARM CPU’s

• ARM version of Domino Server on Linux
• Domino on Docker in the ARM based Apple Silicon M1/M2/M3/M4
• Domino Designer for ARM

How about Emulators?

We have tested running the x86 version of Domino on ARM CPU’s in compatibility mode. While it is somewhat possible, e.g. in a docker container, it is not fun to work with as performance is 10x slower.

Mainframe / zLinux / zOS

HCL Domino is not compiled for Mainframe CPUs and will NOT work on the following

• OS/390 - although older versions of Domino used to support z/OS, see this IBM Redbook
• IBM zLinux
• IBM LinuxOne
• IBM Telum

Please vote this idea if you want HCL Domino to be supporting Mainframes

• Support for Domino on z/OS / zLinux

FreeBSD

FreeBSD is a free and open-source Unix-like operating system, but it is NOT a Linux distribution. HCL Domino is not going to run on this operating system.

Please vote this idea if you want HCL Domino to be supporting FreeBSD

• Idea: FreeBSD version of HCL Domino

Special Linux distributions

The following Linux distributions have been tested but will NOT work with Domino.

• Wolfi OS
