The best ideas
need hardware.
Flux is your AI hardware engineer.
From idea to PCB to shipped product.
ElectronicsMechanicalFirmwareSimulationManufacturing
One project. Every part of the product.
Electronics, layout, enclosure, firmware, and manufacturing live in one project, handled by the same AI engineer.
PCB layout
Placement, routing, stackups, and design rule checks.
Mechanical
Enclosures and brackets around your hardware, each built on the right CAD kernel.

Firmware
BETAStarter firmware for common microcontrollers.
Manufacturing
Live part pricing, availability, and files ready to order.
Describe your idea.
Flux makes it real.
Turn your idea into electronics, mechanical parts, firmware, and manufacturing files with AI, right in your browser.
EngineerManufacturerDesignerGeneral AI writes text. Flux builds hardware.
Claude and Codex are general AI agents. They cannot see your schematic or board, run engineering simulation, or check live part prices and stock. Flux runs the same frontier models inside a complete hardware design environment, in projects that your whole team shares.
Works on the real design
Flux edits the actual schematic, board, and 3D model of your project.
Checks its own work
Circuit, electromagnetic, and thermal simulation, plus design rule checks.
Picks real parts
Flux reads the datasheet and checks live stock and pricing from Digi-Key, Mouser, LCSC, and more before it picks a part.
Already work in Claude Code, Cursor, VS Code, Codex, or ChatGPT?
Connect it to Flux through MCP.Simulates and checks its own work before you build.
Flux doesn't stop at generating designs. The AI engineer simulates and checks its own work with professional-grade solvers, and it shows you the results.
Circuit simulation
SPICE simulation of analog, power, and mixed-signal circuits, with Monte Carlo, temperature sweep, and noise analysis, run and read by the AI engineer.
Electromagnetic simulation
Full-wave simulation of the routed board: signal integrity, power integrity, impedance, S-parameters, crosstalk, and antennas.
Thermal simulation
Flux runs PCB thermal analysis of the routed board at stated operating powers, plus heat and airflow simulation of the enclosure, before you build.
Fluid simulation
Airflow and cooling through the enclosure, so vents, fans, and heat sinks work before the first prototype.
Mechanical simulation
Finite-element stress analysis of brackets, enclosures, and mounts.
Design rule checks
Electrical and manufacturing rule checks on every schematic and board.
Datasheet checks
Reads the datasheet of every part and checks the design against its pinouts, ratings, and limits.
Whatever you're building,
Flux knows the domain.
Ship the next product version in weeks, not quarters.
Flux designs the board, the enclosure, and the firmware together, so they fit the first time.
See Consumer electronics
Medical hardware, checked at every step.
Flux designs the board, the enclosure, the wiring, and the firmware, and checks each change before your design review.
See Medical devices
Boards, parts, wiring, and firmware that change together.
Every robot version changes the electronics, the mechanics, and the code. Flux keeps all three in step.
See Robotics
Industrial products that last. Redesigns that don't take months.
Flux keeps many product versions current, and swaps parts when the supply changes.
See Industrial and connected devices
More design checks. Fewer engineer hours.
Flux does the design work and the simulation, and hands off clean files to your suppliers and your CAD tools.
See Automotive and aerospace
Power hardware, with the math checked.
Chargers, battery packs, and power supplies are easy to get wrong. Flux picks parts that fit your voltage and current, runs the calculations, and checks the design before you order.

Builders love Flux.
“Nothing was more satisfying than seeing our system working in the field, and we really have Flux to thank for it all.”
Michael van Niekerk, Agri-iO
“Flux does not have an upper limit. It gets better every time, makes it easier with every version and not just more precise but also with checks and verifications.”
Dr. Juergen Kienhoefer, AIRcable
“Flux helped kickstart my first PCB design,
50% faster than if I had to use KiCad by myself.”
Melker Wändahl, creator of Tilt Tracker

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
Flux is an AI hardware engineer. It designs schematics and places components. Yes. Ask Flux to route the board or the nets you name, including differential pairs, RF feeds, and power nets. Ask for changes to trace widths, layers, or matched lengths in chat. Keep control of your existing routes and routing rules, and edit the result by hand at any time. AI PCB routing
Yes. Flux imports complete projects from Altium, Cadence OrCAD and Allegro, KiCad, Siemens PADS and Xpedition, Zuken CADSTAR, Eagle, Fusion Electronics, EasyEDA, DipTrace (XML export), and SOLIDWORKS PCB. Schematics, parts, connections, board outlines, and placement come across. Flux imports Labcenter Proteus SDF netlists with Specctra board exports. IPC-2581 revision B and C files become board projects with reusable footprint parts. Altium, OrCAD, PADS, KiCad, Eagle, Fusion Electronics, EasyEDA, and DipTrace part libraries, Allegro footprints, and JEP30 part models become Flux parts. Ask Flux to continue the imported design with mechanical parts, firmware, and manufacturing files.
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 infrastructure with SSO and project-level permissions. Read more about privacy statement.
Flux provides AI for PCB design that works alongside you. As a collaborative AI for electronics, it remains transparent: explaining changes, showing its reasoning, and checking in with you 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.
