Under construction - theme in development.
Neo-brutalist design with sharp edges and bold black shadows. A striking aesthetic that commands attention.
Arca UI started as a side project from an AI site-building agent experiment. Here we explore how AI can craft highly consistent, beautifully styled pages. Multiple designers will iterate on the system over time, with a long-term goal of dozens of themes plus a full agent and workflow stack that makes elegant page building dramatically easier.
We are locking in the core component stack. Sidebar navigation is temporarily disabled while the system is finalized.
Hard Edge Stack embraces neo-brutalism with unapologetic bold design choices. Sharp 90-degree corners, thick borders, and strong offset shadows create a layered, architectural feel that stands out from conventional interfaces.
Cut a release candidate.
Keep the UI crisp: borders first, shadows second, blur never.
"It feels like real paper UI — every layer is legible, every action is satisfying."
Hard shadows keep progress readable on paper-like backgrounds.

"Finally a brutalist theme from arca-ui that still feels premium."
