Magic UI, visual effects without writing them from scratch

Magic UI, visual effects without writing them from scratch

A product landing page has one job: hold attention long enough for somebody to read what it is about. Animation helps with that job and is at the same time the most time consuming part of building such a page, since every effect needs polishing separately.

Magic UI is a set of ready animated components: text appearing letter by letter, numbers counting up, grids responding to a cursor, glowing borders, sliding logo strips. You copy the code into your project and from then on it is yours.

Copying instead of a dependency

This approach works exactly like shadcn/ui and the consequences of that choice deserve understanding.

You install no component library. You pick a component, copy its code into your project, and work with it like your own file. No component package shows up in your dependencies, no updates arrive from outside, and there is no question about what happens if the author abandons the project.

npx shadcn@latest add "https://magicui.design/r/typing-animation"

One caveat: the absence of dependencies covers the set itself, not everything a component drags along. The command above adds the motion library to package.json, since that is where the animation engine lives, and a few components add next-themes as well. The exceptions are effects built from CSS alone, such as the sliding logo strip or the glowing border, which declare no dependency at all.

It also helps to separate two products sharing a name. The component set is open source under the MIT licence and costs nothing. Magic UI Pro is sold separately: over fifty ready page sections and at least nine full site templates, an individual licence at 199 USD one off, perpetual, with commercial use allowed and reselling the code forbidden. The sentence "Magic UI has a ready SaaS template" refers to the second thing rather than the first.

The advantage is full control. A component that almost fits gets fixed in place rather than worked around through properties the author never anticipated.

The drawback is no updates. A bug fix in a component will not arrive on its own, so if a better version appears six months later, you copy it again and carry your own changes over.

On visual components that drawback hurts less than on libraries carrying logic. An animated text component written once keeps working, and adjusting it means changing parameters rather than tracking an external library's interface changes.

What it rests on

The components rest on three things you probably already have in the project.

Styles come from Tailwind CSS, so colours and spacing follow your configuration and a component looks consistent with the rest without adjustment.

Animation uses the library covered in the piece on Motion, previously known as Framer Motion. That means the performance rules applying there apply here too.

Some components extend those from shadcn/ui, so if you already use that set, these join it without conflicts.

The practical consequence: if your project does not use Tailwind, this set makes no sense, since the components would need their styles rewritten. If it does, adding them is one command.

Where it works and where it hinders

Separate two kinds of interface, since the same effect helps in one and hinders in the other.

A page visited once, such as a landing page, a portfolio, or an event site, gains from effects. A visitor sees them once, so animation is an impression rather than a cost. There these components are exactly what is wanted.

An application used daily loses. An effect impressive on first run is, on the fiftieth, a delay between a click and a result. An admin panel with numbers animating on every refresh tires within a week.

A simple test: count how many times a user will see this element. Once or twice in a lifetime argues for the effect. Twenty times a day argues against.

The second test concerns information. Animation showing where a window came from or that an item joined a list carries information. Animation existing for decoration costs the user time and gives nothing.

Performance

Visual effects carry a real price worth knowing before placing three of them on one page.

The base rule follows from how a browser works. Animating opacity and transforms is cheap, since it happens outside layout recalculation. Animating width, height, and position is expensive, since it forces a pass every frame.

The second matter is element count. An effect on one element goes unnoticed; the same one across a grid of a hundred tiles can stutter even on strong hardware. Components responding to cursor movement are the costliest here, since they recompute on every mouse move.

The third is mobile devices. An effect smooth on a desktop can stutter on a three year old phone, and that is where most landing page traffic comes from. Checking on weaker hardware is mandatory here rather than advisable.

The fourth is size. Every component pulls the animation engine along, so a page with one effect should load it dynamically rather than including it in the main bundle.

Accessibility

Some people enable a reduced motion preference in their system, and that is not a matter of taste but sometimes of health.

import { useReducedMotion } from 'motion/react'

const reduceMotion = useReducedMotion()

<motion.div
  initial={{ opacity: 0, y: reduceMotion ? 0 : 24 }}
  animate={{ opacity: 1, y: 0 }}
/>

The right approach is not disabling everything but replacing movement with an opacity change. The element still appears smoothly without travelling across the screen or flickering.

The second matter is content appearing gradually. Text typed out letter by letter looks striking and troubles a screen reader, which reads changing content repeatedly.

<>
  <span className="sr-only">{targetText}</span>
  <span aria-hidden="true">
    <AnimatedText text={targetText} />
  </span>
</>

The final text supplied separately and hidden visually reaches the reader once, whole. The animated version marked decorative is skipped, so the effect goes to whoever is looking and the content to whoever is listening.

The third is contrast. Light effects and gradients can push text legibility below the threshold at which it can be read on a bright screen. Checking contrast against an animated background is harder than against a flat one, so do it rather than assume.

A simple approach freezes the animation on a random frame and measures the contrast right there.

@media (prefers-reduced-motion: reduce) {
  *, *::before, *::after {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;
  }
}

That stylesheet rule is worth adding regardless of the measurement, since it also covers animations from libraries you do not control and which do not check the system preference themselves.

Which effects actually work

The set is large and individual effects vary widely in usefulness. It helps to know which recur in projects and which look good in a catalogue and poor on a page.

The first group carries content. Numbers counting up beside statistics, a strip of customer logos, sections appearing gradually on scroll. Their common trait is that animation underlines information rather than competing with it for attention.

With a logo strip the bottleneck is not the effect but the files. SVGL gathers over six hundred technology marks as vectors, with light and dark background variants, and serves them through an API needing no key, which removes the hunt for each logo separately. Its MIT licence covers the catalogue code rather than the marks themselves, so the right to display somebody else's logo is checked with its owner regardless of where the file came from.

The second group accents a single element. A glowing border on the main button or a subtle effect on a heading. They work while there are one or two per page, since they then lead the eye where you want it.

The third group covers backgrounds and full screen effects. They look most striking in a catalogue and most often hinder in practice, since they lower text legibility and load weaker devices hardest. If you reach for them, check contrast and performance before considering the matter closed.

The fourth reacts to the cursor. Impressive on a desktop and nonexistent on a phone, where there is no cursor.

@media (hover: hover) and (pointer: fine) {
  .card:hover .glow { opacity: 1; }
}

Querying the pointer type is the right tool here rather than checking screen width. A tablet with a stylus and a laptop with a touchscreen both have wide screens and behave differently from a mouse, and a width threshold will not tell them apart. Plan how such an element looks without interaction, since for some visitors that is the only version they will see.

The practical rule: one main effect per page and a few small accents. A page with five equal effects reads as a capability demonstration rather than a product.

Magic UI against the alternatives

The last row is a different category worth separating. Component libraries give buttons, forms, and dialogs with sensible animation. This set gives visual effects a component library does not and should not carry.

In practice both often run together: a component library for the application interface, this set for the landing page. Avoid layering animation from two sources on the same elements, though, since that ends in a double transition nobody planned.

The table has no row for sets from the same shelf, because differences between those are of another kind. Aceternity UI rests on the same foundation, Tailwind and Motion, and is copied in the same way, then parts company in two places. Its effects are heavier, built on large blurs and cursor position maths, so choking scroll performance on a phone comes easier. On top of that sits a paid tier of ready made whole page templates, absent here. Mixing both sets in one project is technically possible and ends with two aesthetics on one page.

The second row deserves more serious thought than convenience suggests. An effect written yourself takes an evening and gives exactly what you want, at a pace consistent with the rest of the project. A ready component saves that evening and brings a look visible on plenty of other sites, because many teams use it. On a product where appearance is the differentiator, that difference sometimes matters.

Effect on page results

A landing page is judged by search engines and by users on how fast it appears and how stably it behaves. Visual effects touch both.

The first is time to a meaningful first view. A page loading an animation engine before showing content makes people wait for something that is not content. The answer is loading effects below the first screen dynamically and keeping only what is immediately visible in the main bundle.

The second is layout stability. An element appearing with animation and shifting the rest of the page makes a user click something other than intended. Reserving space up front, through a fixed container height, removes that.

The third is behaviour on a slow connection. An effect depending on a script that has not loaded leaves an empty area instead of content. Check how the page looks before scripts run, since some visitors will see exactly that state.

The practical order runs like this: first a page working without animation, then effects layered on. The reverse yields a page that looks good on a fast connection and poor everywhere else.

Maintenance in a project

A copied component becomes part of the code, so the same rules apply as to everything else, and it pays to tidy that early.

The first thing is placement. Keep these components in a separate directory, apart from your own, so it is clear what came from outside and what should not be polished without reason.

The second is parameters. A component copied with default durations and delays deserves aligning with the rest of the project immediately, since otherwise every effect runs at a different pace and the page feels incoherent.

The third is removal. An effect that failed its trial and goes unused should leave the repository rather than stay just in case. Unused code complicates searching and reaches the bundle if somebody imports it by accident.

The fourth is recording decisions. A short note on which effects you adopted and why saves discussion on the next page and guards against adding a third effect to the same section.

Common mistakes

The first is using effects in an application people work in daily. What impresses on first run is a delay a week later.

The second is three effects on one page. Attention is a limited resource, so three things competing for it leave the user looking at none.

The third is ignoring the reduced motion preference. It is a system setting chosen deliberately and worth respecting.

The fourth is checking on a desktop only. Most landing page traffic arrives from phones, and effects behave differently there.

The fifth is animating dimensions rather than transforms. The result looks the same and costs many times more.

The sixth is text typed out letter by letter with no screen reader version. It looks good and is inaccessible to some users.

FAQ

Is Magic UI a library?

Not in the classic sense. You copy a component's code into your project and from then on it is yours, with no dependency in the package configuration. It is the same model as shadcn/ui, with the same control advantage and the same lack of updates.

Does it require Tailwind?

Yes, the components use that framework's classes and your colour configuration. In a project without it they would need their styles rewritten, which defeats the main advantage of quick adoption.

Does it suit applications rather than only pages?

Rarely. Visual effects work where a user sees them once rather than twenty times a day. An application interface is better served by utility component libraries with animation tuned to frequent use.

How does it affect performance?

It depends on the effect and the element count. Animating opacity and transforms is cheap; animating dimensions is expensive. Components responding to cursor movement recompute very often, so they can stutter on weaker hardware.

Can it be reconciled with accessibility?

Yes, under two conditions. Handle the reduced motion preference by replacing movement with an opacity change, and ensure content appearing gradually has a version accessible to screen readers.

Components and examples sit on the project site, and the source code in the GitHub repository.
