## What it is
tscircuit is an open-source React/TypeScript framework and toolchain for designing, previewing, simulating, and manufacturing printed circuit boards (PCBs) using code. It includes a CLI, component registry, package manager, autorouter, analog simulation, and exports to fabrication files and KiCad formats.

## Use cases
- design a PCB using React components in TypeScript
- generate electronics with AI coding agents like Claude Code
- preview schematic, PCB, and 3D views in real time while editing code
- export fabrication files to get a circuit board manufactured
- run analog circuit simulations from the command line
- import and export KiCad projects
- review circuit board changes as visual diffs in GitHub pull requests
- share reusable electronic components via a package registry

## When to choose
- you want to design circuit boards in code with version control and code review workflows
- you want AI agents to generate physically-validated electronics
- you prefer a web-development-style workflow (hot reload, components, npm) for hardware
- you need to export to fabrication files or KiCad for manufacturing

## When to avoid
- you need a traditional GUI-first schematic capture and layout tool
- you work on analog-heavy designs requiring advanced SPICE features beyond basic simulation
- you are not comfortable writing TypeScript/React code

## Facets
- artifact type: framework
- maturity: active
- function: sdk, developer-tools, cli, simulation, graphics, build-tool, package-manager
