Every release is published on GitHub releases. Pick the package for your platform below — the file names carry the version number, so grab the one matching the latest release.

Linux

The simplest way is the Snap Store, which keeps Beremiz up to date for you:

sudo snap install beremiz

The snap is built for arm64 as well as amd64, so the same command installs Beremiz on a Raspberry Pi — see Raspberry Pi PLC.

If you would rather not use the store, the same snap is attached to each release as beremiz_<version>_amd64.snap and beremiz_<version>_arm64.snap, and installs with:

sudo snap install --dangerous beremiz_<version>_amd64.snap

Windows

Two packages are attached to every release:

package	what it is
beremiz-windows-installer_<version>_amd64.exe	Ordinary installer. Use this one unless you have a reason not to.
beremiz-windows-portable_<version>_amd64.zip	Unpack and run, no installation and no administrator rights. Useful on machines you do not own.

Both are 64-bit. They are large, because they carry a complete Python and GCC toolchain: Beremiz compiles your PLC program to C and then to native code, so the compiler ships with the IDE.

Source

beremiz-source-package_<version>.zip is attached to each release and contains the sources of Beremiz and of everything it builds against.

To work from Git instead, you need Beremiz and the MatIEC compiler side by side:

mkdir ~/Beremiz && cd ~/Beremiz
git clone https://github.com/beremiz/beremiz
git clone https://github.com/beremiz/matiec

Then follow doc/install.rst, which covers the system packages, the Python virtualenv, building MatIEC, and the optional Modbus, CANopen and BACnet libraries. Once built, the IDE starts with:

~/Beremiz/venv/bin/python ~/Beremiz/beremiz/Beremiz.py

beremiz_public_dist holds the Makefiles, scripts, Dockerfiles and patches used to produce the installers and packages above, if you need to build your own.

What is in the box

component	licence
Integrated Development Environment — configure, write, build and debug PLC programs	GPLv2 or later
Command Line Interface — build and control a PLC from a terminal or a script	GPLv2 or later
Python reference runtime	LGPLv2.1 or later
C++ runtime, for smaller targets	GPLv3 or later

The runtime is under the LGPL on purpose: your PLC program, and the extensions you write for your own hardware, stay yours.
