What is slintcn?

Slintcn is a component library for Slint, a toolkit for building native desktop applications. Rather than installing a package and styling it through a configuration API, slintcn follows the copy-paste ownership model: you run a command to add a component and the source files land in your project. From there you can change colors, adjust sizing, or modify behavior directly without working around a library's constraints. The library currently ships 56 UI components and 8 larger block templates. Components cover a broad range: basic buttons, inputs, cards, and badges, overlays like dialogs, sheets, and tooltips, selection controls like checkboxes, switches, tabs, and radio groups, navigation pieces like a sidebar, breadcrumb, pagination, and menubar, data display components like a sortable data table, calendar, and chart-adjacent progress and skeleton elements, and a small set of game HUD pieces including a hotbar, crosshair overlay, and compass strip. Block templates are for complete screen layouts. The eight available ones cover sign-in, login, pricing, dashboard, settings, team member management, a profile form, and a stats display with traffic bars. Installation uses either a cargo CLI or an npm CLI, and both install the same files from the same hosted registry. Running init sets up a theme token file, after that you add components by name. A lockfile tracks installed versions, and a diff command shows what changed in the registry since your install. The init command accepts a base color argument, with choices including neutral, zinc, slate, and stone. An MCP server is included for AI agent workflows. MCP-capable tools like Claude Desktop or Cursor can connect to it and use tools to list, inspect, and install components directly during a coding session. Documentation for each component is available as a hosted site with per-component pages and a live WASM preview.
