User-Facing Tools

tscircuit is a set of tools around the same circuit-as-code workflow. You can start in the online editor, move to local development with the CLI, and use previewers, converters, and web APIs when you need to integrate tscircuit into a larger toolchain.

Design and Editing

Tool	Use it for	Where to start
tscircuit.com editor	Writing and previewing tscircuit projects in the browser	Quickstart: web editor
tsci CLI	Creating, developing, building, and exporting projects locally	Quickstart: CLI
RunFrame	Embedding a live tscircuit runner inside another web page	Run tscircuit in an iframe

Preview and Inspection

Tool	Use it for	Where to start
PCB viewer	Rendering and inspecting PCB layouts from Circuit JSON	Display Circuit JSON on a webpage
3D viewer	Showing board assemblies with 3D component models	Cad model element
