What each one is
SweetAlert2
SweetAlert2 is a JavaScript library that shows popup dialogs, alerts, confirmations, prompts and toast notifications on a web page. It replaces the plain browser alert and confirm boxes with styled, responsive ones that follow WAI-ARIA accessibility conventions. The README says it has zero dependencies.
toastr
Toastr is a JavaScript library that shows short, non-blocking notification messages (toasts) on a web page, such as info, success, warning, or error messages. Developers call a simple function like toastr.success with a message, and the notification appears and disappears without stopping the user from continuing to use the page. The README says jQuery is required.

Strengths
SweetAlert2
- The README describes it as zero dependencies
- Built to be accessible with WAI-ARIA support
- Customizable and includes several prebuilt theme CSS files in the latest release

- Simple API with info, success, warning, and error methods, as shown in the README
- Options for timeouts, progress bars, close buttons, callbacks, and right-to-left layouts
- Available through npm, yarn, NuGet, Bower, and CDNs
Not ideal for
SweetAlert2
- Projects that do not run JavaScript in a browser, since it is a front-end popup library
- Anyone who needs a fully custom dialog system built from scratch, as this library brings its own look and behavior
- Non-developers who want a no-code tool; using it requires writing code
toastr
- Projects that do not use jQuery, since the README says jQuery is required
- Developers who want a modern, actively updated library, since the last push was in February 2023
- Apps that need notifications beyond the page itself, such as native system alerts
Trade-offs
SweetAlert2
- The README is truncated and does not show the full API, so the depth of customization is hard to judge from it alone
- Much of the README is sponsor listings, which makes the documentation harder to scan
- Its popups are a visual style choice; teams wanting a specific design system may still need to adapt the styles
toastr
- Requires jQuery, which adds a dependency to your project
- Last push was 2023-02-27 and the README lists version 2.1.4 while the latest release is 2.1.1, so maintenance status and version alignment are unclear
- README includes a deprecation notice for older animation options that must be replaced
