See it in context
What it is
A snackbar communicates the result of an operation near the bottom of a surface. A short action such as Undo may let users respond without entering a separate dialog.
When to use it
Use for noncritical task feedback with one simple follow-up.
Know the difference
A snackbar supports a brief action; a persistent banner remains until resolved or dismissed.
Across platforms
iOS · iPadOS · macOS · visionOS
Use the native platform presentation and terminology; adapt density and interaction to touch, pointer, remote, or spatial input rather than copying a phone-sized view.
Web · Android · Windows · Linux
On the web, announce meaningful status changes without moving focus. On Android and desktop, keep messages near the relevant operation and follow the platform’s notification conventions.
