# codex vs solidcraft

codex and solidcraft share 9 technologies: objc2-app-kit, objc2-foundation, keyring, png, image, zip, quick-xml, schemars, and log. Both are written in Rust.

- [openai/codex](https://seerepo.com/r/openai/codex): Lightweight coding agent that runs in your terminal
- [tangency-labs/solidcraft](https://seerepo.com/r/tangency-labs/solidcraft): SolidCraft: an open-source parametric 3D CAD application built in pure Rust. Desktop, web, and automation through MCP.

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
