The framework for AI-generated electronics.
Build real circuit boards with any AI.
Just tell your agent to "use tscircuit"
tscircuit is a TSX framework to enable AI to build electronics.
Using tscircuit, AI achieves state-of-the-art physically-validated
electronics generation capabilities.
AI-native electronics design
Reimagine electronic design, built for AI
Usable with any AI agent. tscircuit doesn't require any special installation- just tell your agent to "use tscircuit" and it gains the ability to create circuit boards
tscircuit boards are
physically verified.

Features
01 · REACT
TSX components for circuits
Compose boards the way you compose UI. Props, children, hooks — but for resistors.
export default () => ( <board width="18mm" height="12mm"> <resistor name="R1" resistance="1k" footprint="0402" pcbX={-4} /> <led name="D1" color="red" footprint="0603" pcbX={4} /> <trace from=".R1 > .pin2" to=".D1 > .anode" /> <trace from=".D1 > .cathode" to=".R1 > .pin1" /> </board> )
02 · AUTOROUTE
Real-time autorouting
Sub-second routing on 4-layer boards. Runs locally with LLM-compatible tweaking.
03 · AI
AI coding skills for hardware
Give Claude Code, Codex, or custom agents the tscircuit skill with the CLI, syntax, workflow, and pre-fab context they need to make useful changes.
04 · FAB
Export every format you need
Download PCB, schematic, and assembly images plus fabrication files, KiCad, DSN, JSON, and netlists from the same board source.
05 · REVIEW

FAQ
Questions people ask before trying tscircuit.
A quick pass over licensing, workflows, imports, and the API surface.
Can I use tscircuit commercially?
You can use tscircuit for commercial purposes. tscircuit is under the same permissive MIT license as Node.js, React, and thousands of other popular projects you are likely already using!
Can I import designs from other software?
tscircuit has some support for importing designs from other software, but it's not yet fully featured. You should file an issue on our GitHub if you'd like to see a specific format supported.
Can I use tscircuit locally?
Yes, you can use tscircuit locally using the tscircuit CLI, but we recommend starting with the web-based application for simplicity.
Can tscircuit make schematics? Is it extra effort?
tscircuit always renders both a schematic and PCB. Unlike traditional EDA where the schematic capture and PCB layout are separate processes, tscircuit combines them by allowing a user to specify constraints and automations. This means that you can design a schematic and then immediately see a PCB layout or vice versa.
What exactly is tscircuit?
tscircuit is a React/TypeScript framework for designing electronic circuits programmatically.
Instead of using traditional graphical interfaces, you write code to define components, their connections, and layout constraints. This "electronics design as code" approach unlocks powerful capabilities like reusable packages, continuous automation, parameterization, and integration with modern software development workflows like version control with Git.
While the core of tscircuit is the framework, the term "tscircuit" often refers to the broader ecosystem built around it. This includes:
- The online development platform and registry (tscircuit.com)
- The command-line interface (CLI) for local development
tscircuit is a modern, web-first approach to hardware development. To learn more about the core concepts and architecture, visit the official documentation.
Can I use tscircuit programmatically?
Yes, you can use tscircuit programmatically with these packages:
- @tscircuit/core - Execute tscircuit React code directly in Node, Bun, or a browser to create Circuit JSON
- @tscircuit/eval - Dynamically run tscircuit code with automatic import handling and transpilation support built in
- @tscircuit/runframe - React components for viewing and running circuits in the browser
How do I display tscircuit circuits on my website?
tscircuit code builds into Circuit JSON, you can then use the
CircuitJsonViewer component inside @tscircuit/runframe to display the Circuit JSON on
your website as a schematic, PCB, or 3D view.
What is Circuit JSON?
Circuit JSON is a JSON format for representing electronic circuits. It is a sort of assembly language for electronic circuits. All tscircuit designs are compiled to Circuit JSON as the intermediary format.
