fluid

fluid is a collection of 6 open-source capabilities designed to create distinct and high-quality user interfaces for projects. Key capabilities include: • Unique brand identity per project brief • Curated database of palettes and typography • Dynamic motion language • Deterministic 23-rule slop detector • Ships production-ready designs • No external API calls for design decisions This system helps developers move beyond generic, template-driven designs by providing a robust framework for consistent and unique visual aesthetics. It ensures that every UI output has a committed identity, leveraging a rich database of palettes and type pairings to generate designs that look custom-made. The integrated motion language adds a layer of sophistication, creating engaging user experiences without complex manual adjustments. The deterministic guardrail, a 23-rule slop detector, runs locally to prevent common design pitfalls such as generic gradients, default fonts, and poor contrast, ensuring high-quality outputs. This means designs meet professional standards without requiring additional review cycles. Fluid integrates seamlessly with popular code assistants and generators, including Claude Code, Cursor, Codex, and Gemini, enabling a streamlined development process. Ideal for engineering teams, product designers, and web studios seeking to rapidly prototype and deploy unique UIs that reflect a strong brand identity. It's especially beneficial for those who want to produce diverse, professional-grade interfaces without extensive design expertise.
