LibrePCB is a free EDA software to develop printed circuit boards. It runs on Linux, Windows and Mac. The project is still in a rather early development stage. See Project Status for more information about the currently available features, limitations and known bugs.

• Cross-platform (Unix/Linux/BSD/Solaris, macOS, Windows)
• Multilingual (both application and library elements)
• All-In-One: project management + library/schematic/board editors
• Intuitive, modern and easy-to-use graphical user interface
• Very powerful library design with some innovative concepts
• Human-readable file formats for both libraries and projects
• Multi-PCB feature (different PCB variants of the same schematic)
• Automatic netlist synchronisation between schematic and board

Official stable releases are provided at our download page.

Please read our user manual to see how you can install and use LibrePCB. The Getting Started guide gives you a quick introduction to LibrePCB.

Contributions are welcome! See our Contributing Guide for details.

For internal details take a look at the automatically generated documentation (doxygen)

WARNING: The master branch always contains the latest UNSTABLE version of LibrePCB. Everything you do with this unstable version could break your workspace, libraries or projects, so you should not use it productively! For productive use, please install an official release as described in the user manual. For development, please read details here.

Instead of building LibrePCB manually, Arch Linux users could install the package librepcb-git from the AUR. The package clones and builds the latest (unstable!) version of the master branch from GitHub.

To compile LibrePCB, you need the following software components:

• g++ >= 4.8, MinGW >= 4.8, or Clang >= 3.3 (C++11 support is required)
• Qt >= 5.2
• zlib
• OpenSSL

Instead of installing the dependencies manually on your system (see instructions below), you can also use one of our Docker images with all dependencies pre-installed (except GUI tools like QtCreator). These images are actually used for CI, but are also useful to build LibrePCB locally.

sudo apt-get install git build-essential qt5-default qttools5-dev-tools libglu1-mesa-dev openssl zlib1g zlib1g-dev libqt5opengl5-dev libqt5svg5-dev
sudo apt-get install qt5-doc qtcreator # optional

sudo pacman -S git base-devel qt5-base qt5-svg qt5-tools desktop-file-utils shared-mime-info openssl zlib
sudo pacman -S qt5-doc qtcreator # optional

1. Install Xcode through the app store and start it at least once (for the license)
2. Install homebrew (the package manager)
3. Install qt5: brew update && brew install qt5
4. Make the toolchain available: brew unlink qt && brew link --force qt5

Download and run the Qt for Windows (MinGW) installer from here. LibrePCB does not compile with MSVC, so you must install following components with the Qt installer:

• The MinGW compiler itself
• The Qt libraries for MinGW

It's important to clone the repository recursively to get all submodules too:

git clone --recursive https://github.com/LibrePCB/LibrePCB.git && cd LibrePCB

When updating the repository, make sure to also update all the submodules recursively. Otherwise you may get strange compilation errors:

git submodule update --init --recursive

You can either build LibrePCB using Qt Creator, or you can build on the command line using qmake. To build a debug version of LibrePCB with qmake/make:

mkdir build && cd build
qmake -r ../librepcb.pro CONFIG+=debug
make -j8

For more detailed instructions (including how to set up Qt Creator), see https://developers.librepcb.org/d5/d96/doc_building.html
