Livewire is a modern electrical design tool for all the engineers who build cables and harnesses as a part of a larger product, but not as a full-time specialty. Start in minutes. Save hours.
Beta access · Free tier available at launch
The Problem
Your current tools were never built for this.
Files fall out of sync
Schematic in one folder, harness layout in another, BOM in a spreadsheet. Version conflicts slow every revision cycle.
Documentation takes weeks
Engineering docs that should be auto-generated get assembled by hand from scattered sources before every design release.
Errors reach the floor
Manual handoffs mean wiring mistakes aren't caught until prototyping or manufacturing — when they're most expensive.
Why Livewire
Powerful enough to be your system of record. Simple enough to start today.
01
Get started in minutes
No installation. No training session. Open your browser, create a project, and start your first schematic. Livewire is built for engineers who don't have time to learn new software.
02
Finish a design in hours
Schematic and harness design are fully connected — changes flow through automatically. What used to span days of copy-pasting now fits in a single afternoon.
03
No building component libraries
Don't spend time building components before you even start designing. Get started quickly with thousands of pre-built components, or choose from our hundreds of high fidelity placeholders parts and assign part numbers at the end.
04
Built for the way you actually work
Start from scratch, import from excel, or begin with a hand-drawn sketch. Livewire meets you where you are and gets you to a manufacturing-ready output faster than any tool you've used before.

Beta Feature Set
Everything you need to ship a harness design.
Schematic Editor
Draw and annotate electrical schematics with connector symbols, wire routing, and signal naming.
Harness design tool
Start a harness design fresh, or build directly from your schematic — changes propagate automatically, no sync required.
AI component search
Find the right connector, terminal, or seal from thousands using natural-language queries.
Import from a spreadsheet
Upload an existing from-to table directly to start building your design from.
Design rule checks
Catch wiring and pinout errors before they reach the prototype build.
Automate documentation
No need to manually build BOMs and connectivity table. All outputs stay synced, and are ready for export in excel or PDF at any time.
Who It’s For
Built for the engineer doing the work.
Hardware Teams
Hardware & electrical designers
Moving from prototype to series production and need a single source of truth for harness design — not a patchwork of folders.
Consultants
Engineering service firms
Delivering harness designs across multiple client projects and need a lightweight, professional tool that doesn’t require a support contract.
Robotics & IOT
Electric systems engineers
Focused on PCB and firmware, but tired of debugging wiring errors at prototype stage that a proper harness tool would have caught.
Upgrade when you’re ready.
After beta, Livewire’s free tier gives you access to schematic and harness design with no time limit. No credit card required. When your workflow grows, our paid plan pricing is within reach for teams of all sizes and stages – with self serve upgrade built in.
