Fulmetry gives coding agents a disciplined way to design circuit boards, run repeatable checks, inspect every result, and produce evidence you can review.

Circuit boards, built like software
Design PCBs with
your coding agent.
Author a board as composable TypeScript, give your agent clear procedures, and move from source to checked, inspectable results without surrendering control of the project.

TRUTH
A successful build means normalized Circuit JSON. Electrical, fabrication, functional, standards, and sourcing results remain independent.
02 / Foundation
BUILT ON.
BUILT OUT.
Fulmetry keeps the circuit engine underneath and builds a controlled, reviewable agent workflow around it.
Built on01
tscircuit
The circuit-as-code foundation for authoring boards in TypeScript and compiling them into Circuit JSON.

03 / Evidence
Honest
by design.
Fulmetry records what the board build and each downstream check actually proved—never what one success merely suggests.

Fulmetry is an independent MIT-licensed project built directly on a pinned tscircuit implementation. It is not a visual editor, an agent runtime, or an official tscircuit product.
