Mainframe icons for React.

31 icons across 7 libraries carry the mainframe tag. Counting each design once (a set's outline and filled wallet are one design), that's 31, which is what the wall shows.

mainframe is a tag: a word for what an icon shows or is for. It is set from each icon's name, its keywords and what it shows, the same way for every library, so a mainframe icon from Lucide and one from Tabler land on this page even when the sets name them differently.

The tags that most often share icons with mainframe are IBM, legacy, system, operating-system and enterprise. They are listed on this page; open one to widen or narrow your search.

Carbon has the most, 23 designs, then VSCode Icons (2) and File Icons (2). Pick one above the wall to see only its icons.

7 libraries draw mainframe icons, each in its own style. The page shows the first ones as rows of how each set draws it, and a picker above the wall narrows it to one library, so you can see mainframe icons that match the rest of your project.

Lucide, the set shadcn/ui ships with, has no mainframe icon here, so use the library with the most designs and keep to its style, or pick one icon per job from the libraries above.

Open a mainframe icon, then copy it as a typed React component or as SVG for Vue, Svelte, Angular or any design tool, or download it as SVG or PNG. Signed in, you can install it with one shadcn CLI command.

Open a mainframe icon, then Get icon, then Copy as code: React, Vue, Svelte, Angular, Solid or Preact. Each is one self-contained component with the SVG inside, so only the icons you import reach your bundle.

Open the icon, choose Get icon, then Install with shadcn CLI, and run the command. It adds one file to components/icons, ready to import. It needs a free account.

Yes. On an icon's page, Customize sets the color, size, stroke, rotation and padding, and every copy and download uses them. 5 libraries here are multicolor and keep their own colors.

Single-color icons are drawn in currentColor, so a Tailwind class recolors them: text-primary, text-muted-foreground or any theme token. Size one with size-5 or size-6.

With a visible label beside it, a mainframe icon is decoration: add aria-hidden="true". Alone, as in an icon button, name the button for what it does ("Pay", not "credit card") with aria-label. The installed component passes every SVG prop through.

Pair it with text when its meaning could be read two ways: icons for mainframe differ from set to set, and a label removes the doubt. Single-color icons use currentColor, so they follow your text color and keep its contrast in dark mode.

Most of them. Of the 31 mainframe designs: 31 are MIT, Apache 2.0, ISC, BSD, OFL or public domain, which allow commercial use with no credit. Each icon's page names its license, so check it before you ship.

None of the mainframe designs counted here asks for credit. 31 are MIT, Apache 2.0, ISC, BSD, OFL or public domain, which need no credit (most only ask you to keep the license notice if you ship their source files). Each icon's page names its license and author.

Yes. Every mainframe icon is free to browse, copy and download here. Pro adds the MCP server, which installs icons for your AI agent.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client search every library and install the mainframe icon you describe.

Ask in plain words, like "a cobol icon". search_icons matches an icon's name, keywords and tags, so the mainframe tag helps it find them, and get_icon installs the one you pick. The tools are search_icons, get_icon and list_icon_libraries.
