ProtoFlow
AI-powered PCB design software for creating production-ready circuit boards
About
The ProtoFlow homepage
ProtoFlow is a free, AI-native PCB design application for Windows, macOS, and Linux that streamlines electronics design workflows. Users can describe circuits in plain language and the AI generates schematics with real components from major distributors, then assist with PCB layout, routing, and simulation. The software includes a full schematic and PCB layout editor, SPICE simulation capabilities, and exports manufacturing-ready files in Gerber format for production.
The tool is designed to work alongside existing EDA workflows. It imports and exports projects in KiCad, Altium, and EAGLE formats, allowing users to integrate ProtoFlow into their existing design processes without vendor lock-in. Every design element generated by AI remains editable, and designs are checked with electrical and design rule checks before fabrication.

FAQ
- What is ProtoFlow?
- ProtoFlow is free AI PCB design software for Mac, Windows and Linux - a full EDA tool with AI integrated into every step. It reimagines the PCB design experience to remove friction and make workflows faster. Users describe the circuit they want, the AI drafts the schematic with real parts and footprints, and they can route the board. All generated content is normal editable geometry.
- Can ProtoFlow simulate circuits?
- Yes. SPICE simulation with ngspice runs directly from the schematic, supporting operating point, transient, AC and DC sweep analyses with a waveform viewer.
- Can I take a board all the way to manufacturing?
- Yes. ProtoFlow exports Gerber X2 files with a job file, Excellon drills with plated and non-plated holes separated, plus BOM and placement files formatted for JLCPCB assembly. One click runs the board through JLCPCB's audit to catch problems before payment.
- Is ProtoFlow free?
- Yes. The free plan does not expire or require a credit card, and includes full access to the editor and AI features. Users can upgrade anytime for increased AI access and higher usage limits, and designs always remain owned by the user.
- Is ProtoFlow a KiCad or Altium alternative?
- ProtoFlow is designed to take you from an idea to a full production PCB without ever leaving it. That said, you are never stuck inside it. Save and export to KiCad, Altium, EAGLE, PADS or EDIF, go work in whatever tool you like, and come back in whenever you need to without losing anything. It is built to be where you start, not somewhere you get trapped.
