Skematiq
Design schematics & wiring harnesses in your browser
Skematiq is browser-based CAD for the electrical side of robots & machines — no install. Instead of scattering it across CAD files, spreadsheets and PDFs, you keep it all in one connected project: block diagrams, pin-to-pin schematics (the label you type becomes the net), cable harnesses with auto connector-pinout tables, and a to-scale panel layout — all kept in sync. A rule check flags conflicts, and wiring lists, BOM and a PDF drawing set fall out at the end. Free to start.
I design electrical systems for machines and robots, and the wiring itself was rarely the hard part — keeping it all organized and consistent was. The block diagram in one file, the schematic in another, the harness list in a spreadsheet, the BOM somewhere else… and they'd drift out of sync the moment anything changed. The "proper" tools (Altium, EPLAN) are heavy, expensive and overkill when you just need a machine wired correctly; spreadsheets and generic diagram apps fall apart the moment it gets real.
So I built Skematiq: browser-based CAD where the whole electrical side lives in one connected project. You sketch block diagrams, draw schematics (the label you type becomes the net), and group wires into harnesses that auto-generate connector pinout tables — and it all stays in sync, so changing one wire updates the harness table, netlist and BOM. When you're ready it exports the wiring list, per-harness sheets, a BOM and a full PDF drawing set — the stuff the assembler needs — but that's just the tail end of keeping everything tidy.
Runs entirely in the browser, no install, free to start.
I'd love your feedback — especially from anyone who's wired a machine and hated keeping the paperwork straight. What should it do next?
the sync between block diagram, schematic, harness table and BOM is the actual product here, everything else is just export formatting. the question that matters for a team adopting this over Altium/EPLAN long term - if a project outgrows Skematiq or a customer demands Altium-native files, is there a real export path, or is a project effectively locked in once it's built here and you'd be redrawing from scratch if you ever needed to leave
Neat idea! I'm more of a mechanical guy but I've tinkered around with a Raspberry Pi to connect to old alarm clock and this would've been helpful for that. Good luck!

Who hunted Skematiq?
Skematiq was hunted by Batuhan Deveci. 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.
