LibreSpin is an open-source, AI-driven platform designed to facilitate end-to-end PCB and embedded circuit design. It enables users to describe their hardware requirements in plain language, and then leverages AI to guide the entire design process, from initial circuit calculations through to the generation of production files. The tool is positioned as a Claude Code harness for hardware projects, aiming to streamline the workflow for those involved in electronic design.
The platform supports a comprehensive design pipeline that begins with a natural language requirements interview, allowing users to specify what they want to build without needing to write detailed technical specifications. LibreSpin then performs AI-assisted circuit calculations, followed by SPICE simulation using NGSpice, and schematic and PCB layout using KiCAD. It incorporates automated checks such as ERC (Electrical Rule Check), DRC (Design Rule Check), and DFM (Design for Manufacturability) to help ensure design quality. The workflow culminates in the export of production files, including Gerber, drill, BOM (Bill of Materials), and pick-and-place data, as well as providing a human review report.
LibreSpin is built on a technology stack that includes Python, KiCAD, NGSpice, and Claude Code. The tool is currently in pre-alpha status and is being developed in public. It is released under the MIT license, making it freely available for use and modification. The project is accessible via its GitHub repository, reflecting its open-source nature and collaborative development approach.
In the Other AI space, LibreSpin takes a focused approach. It focuses on automating and streamlining the PCB and embedded circuit design process using AI. It is built as an open-source project for hardware engineers and embedded system designers. LibreSpin is open source under the MIT license. LibreSpin is available on the web and the command line, and it can be self-hosted.
LibreSpin Contributors builds and maintains LibreSpin, and the product first shipped in 2026. Development happens publicly on GitHub with 70 commits in the last 90 days. Key capabilities include AI circuit design, SPICE simulation, and schematic layout. LibreSpin is currently in beta.
