Are useAnimations Icons Free, Lightweight, and Customizable?

Yes on all three counts, based on the site's own description. useAnimations ships 300 animated icons under the MIT license, with a player that is about 8 kB gzipped and has zero dependencies, and the icons support custom color and size. The MIT license is the part that matters most for commercial work: it permits use, modification, and redistribution, typically requiring only that the copyright notice and license text are preserved. If you need a permissive, no-cost animated icon set for a React or shadcn/ui project, this fits. If you need guaranteed long-term support, a formal SLA, or a vendor to hold accountable, a free MIT library is not that — you would be relying on the community and the repository.

License: what MIT means for your project

The site states the library is MIT licensed. In practice that means:

• You can use the icons in personal and commercial projects.
• You can modify them and redistribute them.
• You generally must keep the license and copyright notice with the code.

The site does not describe any paid tier, account requirement, or usage cap, so there is no indication of a commercial-use restriction. It also does not state anything about attribution requirements beyond the license itself, so treat the standard MIT notice as the requirement rather than assuming attribution is optional.

Size: what the 8 kB figure covers

The published numbers are:

The 8 kB applies to the player, not to every icon you import. That distinction matters: the player is the shared runtime, and individual icons are separate assets. Zero dependencies means the library does not pull in a chain of transitive packages, which keeps your bundle predictable and avoids version conflicts.

For a concrete sense of scale: adding the player plus a handful of icons is a small addition next to most UI libraries. If you import many icons, check your bundler's output rather than assuming the total stays at 8 kB.

Customization: color, size, and styling

The library exposes custom color and size controls, and the site describes the icons as "yours to style." That means you can match them to your design tokens instead of being locked to a fixed palette.

The icons are also described as accessible. The site does not detail the specific accessibility implementation, so verify the rendered markup in your own project — particularly whether icons that convey meaning have appropriate labels and whether purely decorative ones are hidden from assistive technology.

Interactions you get without extra code

Each icon ships with the interaction it was designed for, and you can switch interactions with a single prop. The documented set:

• loop — plays continuously, for loaders and ambient status.
• click-toggle — switches between two states, such as menu and close, or play and pause.
• click-replay — replays from the start on every click, as feedback.
• hover — plays forward on enter and back on leave.
• hover-loop — loops while hovered and finishes its cycle on leave.
• hover-replay — plays once from the start on every enter.

The practical benefit is that you are not wiring animation state by hand for common cases. The trade-off is that these are the built-in behaviors; anything more custom means working with the underlying SVG or Lottie assets.

Formats and integration paths

The site lists three ways to consume the icons:

1. React component — install via npm i react-useanimations, then import.
2. shadcn/ui — add icons through the shadcn workflow.
3. Raw assets — download SVG and Lottie JSON, or a ZIP, per icon.

If you are not on React, the SVG and Lottie downloads are the relevant path. Lottie JSON works with Lottie players across platforms; SVG gives you a static or hand-animatable asset.

When this is the right choice — and when it isn't

Choose useAnimations if you want a permissive license, a small dependency-free player, built-in hover/click/loop behaviors, and easy color and size control for a React or shadcn/ui interface.

Look elsewhere if you need vendor support with commitments, a large icon count beyond 300, or animation behaviors that go well past the six built-in interactions. The site does not publish pricing, so there is no paid tier described here to compare against — the offering as documented is the free MIT library.
