Horizon EDA is a free, open-source Electronic Design Automation package for printed circuit board design. It provides an integrated end-to-end workflow covering parts management, schematic entry, PCB layout, 3D preview, and Gerber export.

Use cases

• design a printed circuit board from schematic to gerber export
• manage a shared pool of electronic parts and symbols
• draw hierarchical schematics with a netlist-aware editor
• route PCB layouts with an interactive router
• preview PCB designs in 3D before manufacturing
• run design rule checks on a board layout

When to choose

• you need a free, open-source alternative to KiCad or commercial EDA tools
• you want an integrated workflow from parts library management through board export
• you value a modern, legacy-free C++ codebase with JSON on-disk format
• you work on Linux or Windows and want GPU-accelerated rendering

When to avoid

• you need simulation or SPICE analysis features
• you require macOS support
• you need integration with an existing KiCad or Altium project ecosystem
• you need FPGA or IC design tools rather than PCB design
