![Engineer holding a green Flux-designed circuit board over a workbench](https://www.flux.ai/p/assets/homepage-v2/hero-bg.webp) # Build. Working. Hardware. 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. Flux takes you from idea to PCB to prototype. Welcome to your hardware era. [Start Building](https://www.flux.ai/signup) ## Let’s make this real. ![](https://www.flux.ai/p/assets/homepage-v2/tier-basic.webp) ### Basic boards. Flux helps you build simple sensor boards, LED controllers, breakouts, and basic microcontroller products that fit comfortably on two layers. Example **NF-Dual Output Buck** [View Project](https://flux.ai/fatenerris/nf-dual-output-buck~cf) ![](https://www.flux.ai/p/assets/homepage-v2/tier-intermediate.webp) ### Intermediate designs. Flux works great for compact microcontroller boards, connected sensors, mixed-signal controllers, and general embedded products. Example **Modern Distortion Effects Pedal** [View Project](https://flux.ai/cherepanyadima/modern-distortion-effect-pedal-v1~w0) ![](https://www.flux.ai/p/assets/homepage-v2/tier-advanced.webp) ### Advanced products. Flux excels at compact designs with fine-pitch components and dense routing, such as wearables, processor boards, and camera or display electronics. Example **ESP32 x86 PC** [View Project](https://flux.ai/vasy_skral/esp32-x86-pc~rzy) ![](https://www.flux.ai/p/assets/homepage-v2/testimonial-1.webp) > “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 [Read Case Study](https://www.flux.ai/p/blog/agri-io-revolutionizes-farming-with-flux) ![](https://www.flux.ai/p/assets/homepage-v2/testimonial-2-boards.webp) > “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 [Read Case Study](https://www.flux.ai/p/blog/why-dr-juergen-kienhoefer-switched-to-flux-after-15-years-of-eagle) ![](https://www.flux.ai/p/assets/homepage-v2/testimonial-3.webp) > “Flux helped kickstart my first PCB design, > 50% faster than if I had to use KiCad by myself.” Melker Wändahl, creator of Tilt Tracker [Read Case Study](https://www.flux.ai/p/blog/building-tilt-tracker-first-pcb-in-flux) ## Flux is your AI hardware engineer. ![](https://www.flux.ai/p/assets/homepage-v2/engineer-card-1.webp) ![](https://www.flux.ai/p/assets/homepage-v2/engineer-card-2.webp) ![](https://www.flux.ai/p/assets/homepage-v2/engineer-card-3.webp) Brainstorm Tell Flux what you're trying to build and why. It asks questions, researches the approach with you, and turns the conversation into a real plan. Design Flux transforms the project plan into a working schematic, lays out components, and tests the design against engineering rules. Make Flux shows you what each part costs and how long it takes to arrive, then packages all files according to manufacturer specifications.

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. Now validating: - Schematic legibility - Electrical rule check - Design rule check ## Boot up your hardware era. Get started with Flux in the browser right now.

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](https://www.flux.ai/p/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: - [Eagle to Flux](https://docs.flux.ai/Introduction/eagle-to-flux---migration-guide) - [Upverter to Flux](https://docs.flux.ai/Introduction/upverter-to-flux) - [KiCAD to Flux](https://docs.flux.ai/Introduction/kicad-to-flux) - [Altium to Flux](https://docs.flux.ai/Introduction/flux-to-altium-migration-doc) - [EasyEDA to Flux](https://docs.flux.ai/Introduction/easyeda-to-flux) ### 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](https://docs.flux.ai/Introduction/getting-started-in-flux-manufacturing) ### 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.
