PCB Design Software
PCB design software that runs in your browser with AI that handles the hard parts, real-time collaboration, and no install.
PCB design from idea to manufacturing with the help of AI
Flux is a PCB design software that works like an AI hardware engineer: handling complex tasks, learning your standards, explaining its decisions, and collaborating with you at every step.
Describe
Tell Flux what you're building. AI maps out your schematic and BOM for your PCB design.
Design
Refine your layout with AI-assisted routing and real-time collaboration.
Manufacture
Export Gerbers, BOM, and pick-and-place files, then order from any manufacturer.
5 Reasons to Choose Flux as Your PCB Design Software
More than traditional PCB design tools. A cloud-native, AI-powered PCB design software platform.
1. AI-Powered PCB Design That Handles the Tedious Work
Flux AI takes on part research, component placement, route optimization, and design rule checks so you spend less time on repetitive PCB design tasks and more time on the decisions that matter.
"From hours to minutes on routing iterations"
2. Real-Time Collaboration, Like Google Docs for Hardware
Multiple engineers on the same board, at the same time. Comment, review, and iterate on your PCB design without emailing files back and forth. Version history built in.
PCB design teams ship 40% faster with real-time review.
3. Browser-Based — No Install, No License Keys
Open a tab and start your PCB design. Flux runs entirely in your browser with no downloads, no license management, no OS compatibility headaches. Works on Mac, Windows, Linux, Chromebook.
4. Complete PCB Design Workflow in One Platform
Schematic capture, PCB layout, simulation, BOM generation, and Gerber export all in one PCB design software. No more switching between tools, no file format juggling.
5. Start Free, Scale When Ready
Flux includes plans for personal projects and growing teams. See current pricing.

Frequently Asked Questions
What is PCB design software?
PCB design software is a tool that lets engineers create schematics, design board layouts, place components, route traces, and export manufacturing files. Flux is PCB design software that runs entirely in the browser with AI assistance built in.
How much does Flux cost?
Eligible individual plans include a free trial; Teams subscriptions start paid. Explore supports learning. Build supports a first board. Pro supports product delivery. Teams supports organizations. See current pricing.
What makes Flux different from other PCB design software?
Three things: it's browser-based (no install), AI-powered (handles part research, placement, routing, and design checks), and collaborative (real-time multiplayer like Google Docs). Most PCB design software requires a desktop install, has no AI, and forces you to work alone.
Can I import projects from Altium, Cadence, or KiCad?
Yes. Flux supports importing from KiCad, Eagle, Altium, and other common EDA formats. Your existing libraries and footprints carry over.
Can I export for manufacturing?
Yes. Export Gerbers, BOM, and pick-and-place files for any manufacturer. Flux is compatible with PCBWay, JLCPCB, OSH Park, and others.
How capable is the AI, and what are its limits?
Flux AI handles part research, schematic generation, component placement, route optimization, and design rule checks. It works best as a collaborator: it makes suggestions and explains its reasoning, and you make the final call. It accelerates your workflow but does not replace engineering judgment.
What is the difference between PCB design and PCB layout?
PCB design covers the full workflow from schematic to manufacturing. PCB layout is one step within that, focused on component placement and trace routing on the physical board. Flux handles both in one platform.
Can multiple engineers work on the same PCB design?
Yes. Flux supports real-time collaboration with multiple engineers on the same schematic and layout simultaneously. Changes sync instantly, and version history tracks every edit.
