Score: 6.0/10 (Innovation: 7, Technical: 6, Documentation: 4, Utility: 5)

C'est is a native Mac CSS editor that visualizes CSS rulesets as draggable nodes with automatic indentation for descendant selectors, and provides visual tools for media queries, variables, and property editing. It's interesting because it reimagines CSS authoring as a spatial, node-based interface rather than a text editor, making relationships between selectors and responsive variants immediately visible.

Target audience: frontend devs, designers, web developers
