Rivet

Rivet is a design agent that works inside a coding agent. Instead of producing a single mockup, it explores dozens of design directions for a piece of software in parallel, shows them side by side, and lets the designer pick the direction that fits and refine it. It is built for designers and developers who craft software with AI coding tools. Rivet installs with one click into Claude Code, Codex and Cursor, and it connects as an MCP server. Designers can bring in inspiration from Pinterest, Are.na and local files so the generated directions follow their own references. Directions are grouped by kind of change, for example layout changes or rough explorations, and each is compared against the original running page, which the demo shows on a local development server. Results can be shared. The vendor describes its purpose as helping designers explore more ideas, and its story page frames the product as a design partner rather than another drawing tool, tracing a line from parchment and drafting tables to modern design software. The vendor does not publish pricing. Its pricing path returns the home page, and no plan prices, free tier or trial terms are stated.
