perfwire
AI can design your circuit. It can't see your perfboard.
A browser-based wiring planner and checker for hand-soldered perfboard. Drag parts to match your real board while a rule-checker — implemented twice, in JS and Python, and verified to agree in CI — catches shorts, backwards parts, and missing connections before you solder. One HTML file, free, no install.
I've been building electronics for a while now — both as a personal hobby and as part of projects at work. I'm not an EE, and these days I can get an AI to design a circuit for me in about a minute. But wiring it onto an actual perfboard by hand? That's where it always fell apart — one jumper in the wrong hole and nothing works, with zero clue which of a hundred joints is the bad one.
What really bugged me was the gap between working with Claude Code and the reality on my bench. Claude could hand me a clean design in seconds, but the moment I picked up the soldering iron I was on my own — no way to check my physical wiring against what the AI actually intended.
So I built perfwire: a browser tool that plans and checks hand-soldered perfboard wiring the way a real board behaves, not an abstract schematic. It models individual holes and leads, so it catches shorts, backwards capacitors, and connections that never got made — before you pick up the iron. There's a 3D view now that finally lets you see where a wire actually goes on a crowded board.
It's one HTML file: no install, no account, works offline, and a board shares as just a URL. Use it standalone, or in a loop with Claude Code — describe a circuit, get a board back, drag it to match reality, hand it back, repeat. That loop is exactly the gap I wanted to close.
It's free and open source (Apache 2.0).
I'd love feedback, especially from anyone who's fought with perfboard by hand: what's the mistake that always gets you?
How does the rule checker handle parts with non-standard pinouts like transistors or voltage regulators that vary by manufacturer? Curious if I'd need to manually define each footprint or if there's some kind of common library built in.
Dragged a few resistors onto a perfboard layout and the rule-checker immediately caught a backwards LED I would have definitely missed. Love that it's just one HTML file with no install fuss.
drag a couple parts onto a board and the rule checker just works, caught a reversed diode i almost missed. love that the whole thing is a single html file.
A really useful idea would be to add a way to print or export the layout as a 1:1 template so you can tape it to the physical perfboard and punch through component leads at the exact spots. Right now I'd still have to eyeball placements during soldering, but a scaled print would let the digital plan match the real board one-to-one.

Who hunted perfwire?
perfwire was hunted by Yusuke. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
