The first AI intern for PCBs
Introducing a new way to work: Give Flux a job and it plans, explains, and executes workflows inside a full browser-based eCAD you can edit anytime.
AI help from idea to PCB
Work with Flux like an engineering intern—automating the grunt work, learning your standards, explaining its decisions, and checking in for feedback at key moments.
01
Plan
Describe what you want to build.
Flux understands your requirements and maps out a detailed plan for your approval.
Flux understands your requirements and maps out a detailed plan for your approval.
02
Schematic
Flux generates conducts research, generates BoMs and schematics while checking in at key points to get your feedback and direction.
03
Layout
AI places parts and routes your design with awareness of your constraints — delivering layouts continue to optimize.
04
Manufacture
Outputs are ready for fab, with sourcing-aware parts suggestions to reduce cost and avoid supply risks.

Why engineers choose Flux
Hardware is entering a new era, led by engineers who embrace AI. Flux is the platform built for them—with automation, collaboration, and intelligence that improves with every design.
Live component data
Design with real inventory, pricing, and alternates—your BoM is always ready to source.
Real-time collaboration
Work together at the speed of thought with version control and advanced permissions.
Works anywhere
Browser-native design means no downloads, instant sharing, and access from any device.
Transparent AI
Every action is explainable, reviewable, and reversible—you stay in control.
Smart guardrails
Automated design rule checks, supply chain monitoring, and manufacturability validation.
Human Support
Fast help from real engineers and an active builder community.
Our vision
Taking the hard out of hardware
Unlike software, building hardware is still insanely difficult. If you’re working with atoms, the costs are high, the risks are significant, and the timelines are long.
We founded Flux to make atoms as malleable as bits. We want to take the hard out of hardware, making it as easy for a teenager to build an iPhone as it is to create a website. Read more about Flux manifesto.

Frequently Asked Questions
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 $15 per month for starter, $39 per month for pro, and $49 per month for teams. Each tier includes a number of monthly AI credits. Beyond that, additional AI credits 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.
