See inside
every circuit.
Blocks that explain themselves — and catch what doesn't add up.
A live Electrace design — hover a block to see what it does. And the linter just caught a 24 V brick feeding an 18 V-max regulator, before it shipped.
Other tools stay silent — or just guess.
Electrace is the one that shows you why.
An IDE — for circuits.
Self-explaining blocks
Authored intent, not guesses. Every block says what it does and why.
Drill into anything
Double-click into a block's real schematic — discrete or IC, every part labeled.
Linting, not SPICE
Voltage and current follow every wire — over-voltage, blown budgets, broken isolation, and overloaded connector pins get caught with the where and the why.
Open any block.
Read every part.
The one IC stops being a mystery — you see exactly what surrounds it, and why.
- ✓ A plain-language reason on every part.
- ✓ ANSI or IEC symbols — your choice.
An AI assistant
that doesn't get to guess.
Didn't we just say copilots guess? They do — because nothing checks them. Sparky is different by construction: everything it draws goes through the same deterministic linter as your own work. Every wire resolved, every budget recomputed, every claim checkable.
- ✓ Builds from real, spec'd blocks — with a real BOM, not invented part numbers.
- ✓ When it's wrong, the checker says so. Out loud, on the canvas.
- ✓ Explains every choice in plain language — it's a tutor, not an oracle.
Nothing
forgotten.
Connect net-to-net — 5 V to 5 V, ground to ground. Leave one dangling and Electrace tells you, right there.
Not guessing. Not SPICE.
Not locked in.
Design it. Understand it. Build it.
Electrace is a free, browser-based circuit and PCB design tool built around one idea: you should be able to see inside every circuityou build. Every block carries its real schematic and the reasoning behind every part; the checking engine follows voltage and current through every wire and tells you where — and why — something won't work. Draw the schematic, lay out the board, export to KiCad, order the parts. No simulation setup, no install, no vendor lock-in.
