Ink-lined capsules with bold outlines and full-round geometry. Every element behaves like a self-contained capsule, aligned by a strict, consistent system.
Arca UI originated from an intensive experiment in building AI-powered site-building agents. While the agent tool itself is currently on hiatus, the project led to a deep exploration of how AI can achieve high-fidelity, consistent, and elegant front-end architecture.
Through this process, I've developed dozens of aesthetically cohesive design themes and refined a series of complex workflows and debugging systems. Now, I am systematically releasing these findings as a component library. My goal is to empower indie hackers and small teams by providing pre-optimized, production-ready UI blocks that save hundreds of hours typically spent on styling and debugging.
Each feature, line of copy, and piece of media is treated as its own capsule. They float on a clean canvas—distinct yet harmonized by the same strict spacing, outline weight, and alignment rules.
