“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

Take the hard
out of hardware.
Flux does the engineering work that normally makes hardware hard.
Flux catches issues in real time by continuously running electrical and design rule checks,. It grounds its decisions in the actual parts by reading datasheets. It handles the details – sizing passives, I²C pull-ups, and decoupling caps. Flux works dynamically instead of following a rigid plan, re-evaluating work after each step and course correcting.

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.
