October Themes

Browse over 1,000 curated design systems for AI coding tools. Give your agent a consistent visual reference for colors, type, spacing and components.

Use themes with your coding tools

October Themes includes a free MCP server and an agent skill. Use them with tools such as Claude, Cursor, VS Code and Windsurf. No API key is needed.

The gallery includes references for websites, mobile apps and desktop interfaces. Select a theme that fits the product you are building, then share that design system with the agent working on your interface.

For agents

Read the agent-readable guide, browse the public themes API, or get the MCP package.
