Flux is a PCB design software that works like an engineering intern: automating the grunt work, learning your standards, explaining its decisions, and checking in for feedback at key moments.

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.
More than traditional PCB design tools. A cloud-native, AI-powered PCB design software platform.

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"

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.

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.

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.

Flux's starter tier includes everything you need for personal projects and learning. When your team grows, Pro and Enterprise plans add advanced collaboration, priority support, and team management.
More than traditional PCB design tools. A cloud-native, AI-powered PCB design software platform.
Flux AI handles part research, schematic generation, component placement, routing, and design rule checks. Describe what you want to build, and AI delivers a starting point you can refine.
Create and edit schematics with a full component library. Every change syncs instantly to your PCB layout, keeping your design consistent throughout.
Place components, define board outlines, and route traces with AI assistance. Flux supports multi-layer designs with impedance-aware routing and real-time DRC.
Design with real-time inventory, pricing, and alternate part suggestions. Your BOM is always sourced and ready to order.
Validate your design before manufacturing with built-in SPICE simulation. Test circuits, verify parameters, and catch issues early.
Work with your team in real time on the same schematic and layout. Built-in version control, comments, and role-based permissions keep everyone aligned.
Work with Flux.ai like an engineering intern: automating the grunt work, learning your standards, explaining its decisions, and checking in for feedback at key moments.

Loved by engineers pushing hardware design forward.
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.
When you sign up you get a free two-week free trial — risk-free, cancel anytime. Then paid plans start at $20 per month for starter, $142 per month for pro, and $158 per month for teams. Each tier includes a number of monthly ACUs. Beyond that, additional ACUs are charged based on your usage, with a configurable spend limit.
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.
Yes. Flux supports importing from KiCad, Eagle, Altium, and other common EDA formats. Your existing libraries and footprints carry over.
Yes. Export Gerbers, BOM, and pick-and-place files for any manufacturer. Flux is compatible with PCBWay, JLCPCB, OSH Park, and others.
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.
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.
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.
