When to use
- Inline status messages in the page for success, info, warning and error outcomes
- Notices that offer a next step, such as a security update, a renewal reminder or a plan upgrade
- Status rows set inside a Frame panel, such as service health, deploy results and message notifications
When not to use
- A yes or no decision that must be answered before the page goes on: use the Alert Dialog component
- A brief confirmation that floats in a corner and disappears by itself: use the Sonner component
- A complete modal task, such as a plan cancellation form that holds a warning banner: use the Dialog blocks

Shadcn Alert is the callout primitive for status, validation, billing, and system messages. It maps to WAI-ARIA alert and status roles so assistive technologies announce important content without breaking your layout.
Built for the React and Tailwind ecosystem, it works with Radix UI and Base UI-style projects because styling stays token-driven. Shadcn Create style options apply to alert surfaces so what you tune in the customizer matches exported code.
ReUI lists alert components in real dashboards and forms so you compare density, icons, and actions next to a Shadcn Card or table, not a lone sandbox. The sections below cover what it is, why teams use it, features, and integration ideas.
What is Shadcn Alert?
In product UI, an alert is a persistent or dismissible region that highlights an outcome, risk, or next step. Shadcn Alert composes title, description, and optional icon or actions while keeping roles and labels consistent with WAI-ARIA guidance.
Components here show stacked alerts, billing warnings, and inline actions. They help you decide density, contrast, and placement before you wire the same component into Next.js, Vite, or a server-rendered React tree.
Why Use Shadcn Alert?
Teams use alerts when users must notice state without opening a modal. That includes payment failures, form errors at the top of a page, or irreversible actions that need a short explanation and a primary Shadcn Button.
Shadcn Alert Features
- WAI-ARIA Aligned. Uses roles and semantics that match WAI-ARIA roles for alerts and status messages so screen readers can surface urgency without guessing.
- Radix UI and Base UI Friendly. Styling uses semantic tokens and composition that fit Radix UI projects and Base UI-style unstyled layers when you bring your own primitives.
- Shadcn Styles and Create. Fully compatible with Shadcn Create: try the style customizer above the component grid to preview radius, fonts, and colors on the same alert variants you will export.
- React and Tailwind First. Written for modern React with Tailwind CSS utility classes; pair with the shadcn CLI workflow (npx shadcn@latest add alert) to add source to your repo.
- Variants and Actions. Success, warning, destructive, and neutral treatments with optional actions or links, aligned with your design system tokens.
ReUI Alert: In-House Custom Shadcn Component
ReUI Alert is an in-house component built and maintained by the ReUI team as part of the ReUI open-source library. It is designed to integrate seamlessly into any shadcn/ui project: following the same copy-and-own installation model. The component source lands directly in your repository; you own it, extend it, and style it with your Tailwind CSS tokens. ReUI Alert extends the standard shadcn Alert with additional variants: success, warning, info, and invert: each backed by dedicated CSS variable tokens. This makes it a drop-in replacement that covers the full semantic range modern products need without patching base shadcn.
The component is available in two API flavors to match your primitive stack: a Radix UI version for teams using Radix-based shadcn primitives, and a Base UI version for teams on @base-ui/react. Both versions share identical visual output and Tailwind CSS styling: only the underlying headless primitive differs. ReUI maintains 22 such in-house components, all available in both Radix and Base UI versions, each with dedicated documentation covering the full component API, usage examples, and prop references.
Integrating with Other Components
Pair alerts with a Shadcn Button or link group for primary and secondary actions such as retry, view details, or dismiss when your product allows it.
Place alerts inside a Shadcn Card or at the top of a Shadcn Field group so validation errors stay near the inputs they reference.
For blocking decisions, route users to a Shadcn Dialog or Shadcn Alert Dialog while alerts handle non-modal status that should remain visible in the layout.
