# Cap vs wgpu

Cap and wgpu share 6 technologies: Tokio, objc2-foundation, winit, ash, log, and objc2-quartz-core. Both are written in Rust.

- [CapSoftware/Cap](https://seerepo.com/r/CapSoftware/Cap): Open source Loom alternative. Beautiful, shareable screen recordings.
- [gfx-rs/wgpu](https://seerepo.com/r/gfx-rs/wgpu): A cross-platform, safe, pure-Rust graphics API.

- 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.
