Foss Warn

The FOSS Warn icon represents a warning or alert. It visually depicts a stylized representation of a warning sign or an alert symbol. The origins of this symbol are likely rooted in software development or security.

In real-world applications, this icon appears in software development platforms, warning or alert systems, and security related tools. For instance, it might be used in FOSS software, warning apps, or security software.

From a UX perspective, this icon communicates the idea of caution or warning. It helps users understand that the related functionality involves alerting them to potential issues or security threats.

Foss Warn is one of 14,082 icons in Arcticons, made by Donnnno and released under CC BY-SA 4.0. It is drawn on a 48 × 48 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds FossWarnIcon to components/icons/arcticons-foss-warn.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed FossWarnIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Foss Warn icon, or any of 14,082 Arcticons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 48 × 48 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Foss Warn", so screen readers say what it does.

Yes. FossWarnIcon passes every SVG prop to the svg element, so <FossWarnIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes, with conditions: CC BY-SA 4.0 asks you to credit the author (Donnnno), and icons you change must use the same license. The full terms are in the license, linked on this page.

Yes. CC BY-SA 4.0 asks you to credit Donnnno, and icons you change must be shared under the same license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are development, software, security, notification, warning and alert. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Foss Warn in another set.
