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.
Describe
Tell Flux what you're building. AI maps out your schematic and BOM.
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 EDA. A cloud-native, AI-powered design platform.
Flux AI takes on part research, component placement, route optimization, and design rule checks so you spend less time on repetitive tasks and more time on the design that matters.
"From hours to minutes on routing iterations"
Multiple engineers on the same board, at the same time. Comment, review, and iterate without emailing files back and forth. Version history built in.
Teams ship 40% faster with real-time review
Open a tab and start designing. 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 are all in one workflow. No more switching between tools, no file format juggling.
Flux's free 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.

Loved by engineers pushing hardware design forward.
Flux supports professional multi-layer PCBs up to eight layers used in IoT devices, wearables, and robotics. Built to go all the way from prototype to production. Featured projects
Yes — schematics from Altium (ASCII) and Cadence (EDIF) import into Flux; KiCad part libraries can be imported to bring your components across. Layout import isn’t supported yet.
Importing projects from:
Yes. Flux exports Gerbers, drill files, BoM, pick-and-place, and standard netlists for fabrication and downstream tools. Exporting projects
Yes. Flux encrypts data in transit and at rest and runs on SOC-2–aligned, cloud-native infrastructure with SSO and project-level permissions. Read more about privacy statement.
Treat it like a fast junior engineer: powerful, but you must review its work. We recommend intermediate PCB experience; Flux explains changes, shows reasoning, and checks in before key steps.
Flux is built to feel like a desktop-class tool without installs: large, multi-layer designs run smoothly in a modern browser, with real-time collaboration built in. Learn how to setup your browser to ensure the best possible experience.
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. Plans and pricing
You’re not alone. Our team and community are active in Slack, with docs, Youtube videos, and fast support when you need it.
Flux is full ECAD rebuilt for the AI era: browser-based, collaborative, connected to live parts data, and guided by explainable AI. See KiCAD vs. Flux, EasyEDA vs. Flux to learn about key differences.
