Here’s how Flux works
You know what you want to build. Flux knows how to get it onto a board. It plans the design with you, explains every decision, and checks in before anything important, so you're never guessing whether it's right.
01
Describe your idea Describe what you’d like to build
Flux turns your idea into a plan you approve before any work starts.
02
Flux drafts the schematic
It researches the parts, builds your BoM, and wires it up.
03
Flux lays out the board
AI places and routes it. Nudge anything, anytime.
04
Order it, ready to manufacture
Design checks and in-stock parts, so it works the first time.
Why people 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.
Real-time collaboration
Work on the same board at once, with version history and permissions.
Works on any device
It's just a browser tab. No installs, and it runs on Mac, Windows, Linux, and Chromebook.
Transparent AI
Every action is explainable and reversible. You stay in control.
Smart guardrails
Design-rule checks, supply-chain monitoring, and manufacturability, all automatic.
Human Support
Fast answers from real engineers, plus an active builder community.
Hardware people have a lot to say about Flux.
From first-time PCB designers to space engineers, founders, software developers, and manufacturing teams — these are the people actually building hardware in Flux.
I am a Senior Software Developer with more than 20y experience and I felt its time for something new. You Instagram Ad caught me and now Im fully in, my mission is to build and assemble a real working hardware product, eventually scale and sell it.

The experience with Flux is incredible, with the integration of Chat vs. Agent where you can research and discuss design before having the Agent move forward. It's like having a personal research assistant who can build your parts list and verify your design.

I got help from a few employees at flux. Especially Vasyl who made my 4 layer pcb into a 2 layer pcb and choose simpler parts for me. This would have been difficult to figure out myself.

Before I found Flux, I was in perpetual prototype mode. Not being an electrical engineer, the process seemed so daunting I kept putting the task off. The Flux platform enabled me to have a production ready prototype for my business in less than 2 weeks!
