Livewire is the unfair advantage your team has been looking for
Livewire is the browser-based software for cable and wire harness design, built for early-stage hardware teams: robotics, drones, EV, medical devices, and more. Start designing in minutes, seamlessly, at any skill level.
Take your napkin sketch to a final schematic and harness design in an afternoon
Early hardware teams don’t usually lose to bad engineering. They lose to time. The schematic, the cut list, and the reasons behind both often come at the end of the design, creating problems later in the process.
Zero learning curve, a new engineer can pick it up on day one and design concurrently with the rest of the product.
Knowledge stays with the team
Everyone works from the same live project instead of one engineer’s laptop.
Your CM builds what you designed
Contract manufacturers get a clean wiring diagram and a real bill of materials, speeding up delivery.
Catch issues before the build
Find a reversed pin or a missed connection on screen, not after the first prototype comes back.
Everything your team needs to get to prototype and production.
Capable enough to be your system of record. Simple enough that no one needs a training session to open it.
Schematic editor
Route your wiring diagram with connector symbols, pin call-outs, and wire gauge, in one click with our AI tidy feature.
Harness design tool
Build the physical harness straight from your schematic. Change a pinout once and the whole harness updates automatically.
Pre-built component library
Search from thousands of connectors, terminals, and seals in plain language instead of digging through a distributor catalog at 1am.
Design rule checks
Catch a reversed pin or a short before it reaches your prototype, not after the build.
Auto-generated documentation
Bills of materials, connectivity tables, and harness drawings stay in sync. Use them in pitch decks or for engineering handoff.
Import from Excel
Already tracking a from-to table in a spreadsheet? Pull it straight in and keep building instead of starting over.
One harness design tool for every kind of hardware startup.
Different product, same headache: too many wires, not enough documentation. Livewire fits early hardware teams of any kind.
Robotics & automation startups
Move from a one-off prototype harness to something the next hire can actually maintain.
Drone & aerial systems teams
Keep flight-critical wiring documented well enough to survive a design review, not just a test flight.
EV & mobility hardware
Chase down a wiring issue on the bench, not on a demo.
Medical device & consumer hardware
Harnesses documented well enough for your contract manufacturer and for regulatory approval.
As you grow, hand it off clean to your next hire.
Join Livewire’s beta, stay with us for the release, and receive your first year on us. Your project carries over hire to hire, so the next engineer inherits a working system, not a folder of leftover files.
