Overview of Projects

tscircuit is split into many small packages and apps. Use this page to pick the right repository before opening an issue or pull request.

Where to Start

New contributors should start with tscircuit/schematic-symbols, tscircuit/footprinter, or tscircuit/docs.
UI contributors should look at tscircuit/tscircuit.com, tscircuit/runframe, tscircuit/pcb-viewer, or tscircuit/3d-viewer.
Compiler and library contributors should look at tscircuit/core, tscircuit/circuit-json, tscircuit/props, or tscircuit/circuit-to-svg.
Converter and automation contributors should look at the CLI and converter repositories listed below.
