From idea to PCB with the help of AI

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.

01

Describe

Tell Flux what you're building. AI maps out your schematic and BOM.

02

Design

Refine your layout with AI-assisted routing and real-time collaboration.

03

Manufacture

Export Gerbers, BOM, and pick-and-place files, then order from any manufacturer.

5 reasons why engineers switch to Flux

More than traditional EDA. A cloud-native, AI-powered design platform.

1. AI 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 tasks and more time on the design that matters.

"From hours to minutes on routing iterations"

Why are engineers switch to Flux

Loved by engineers pushing hardware design forward.

Founder of DirtyDevices

Tim Wagner

"As a startup founder building an IoT device for construction machinery, I took my product from concept to production entirely in Flux with no external EE help. We even raised $187K on Indiegogo. Flux made it possible."

Praxis Manufacturing Founder

Nick Parker

"This is Figma for circuit design - ridiculously slick software in a space where everyone else's UX is stuck in 2005. I'm beyond hyped to see this take over!"

PhD researcher in CTS

Nabhan Fakrudin

"Next-Generation EDA; Absolutely phenomenal support and design experience. Added value with the post-design reviews before manufacturing"

Frequently Asked Questions

What kinds of boards can I design in Flux?

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

Can I import projects from Altium, Cadence, or KiCad?

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:

Can I export for manufacturing?

Yes. Flux exports Gerbers, drill files, BoM, pick-and-place, and standard netlists for fabrication and downstream tools. Exporting projects

Is my data secure?

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.

How capable is the AI — and what are its limits?

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.

How does Flux perform in the browser?

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.

How much does Flux cost?

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

How do I get help if I’m stuck?

You’re not alone. Our team and community are active in Slack, with docs, Youtube videos, and fast support when you need it.

How is Flux different from traditional ECAD tools?

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.
