Floating UI vs Tippy.js vs Radix Tooltip: Popover Positioning 2026

TL;DR

Building tooltips, popovers, dropdowns, and floating menus correctly is deceptively hard — viewport overflow, collision detection, scroll containers, and keyboard accessibility are all gotchas that custom solutions routinely miss. Floating UI (successor to Popper.js from the same authors) is the low-level positioning engine — pure geometry and collision detection, totally unstyled, works with any framework, and is what Radix, Mantine, and many others use internally. Tippy.js is the batteries-included tooltip library built on Popper.js — styled out of the box, declarative API, animates, works in vanilla JS and React — but it's showing its age in 2026 with no App Router support and weaker accessibility guarantees. Radix UI's Tooltip and Popover are headless, fully accessible (WAI-ARIA compliant), React-only components built on Floating UI internally — the correct choice for React/Next.js component libraries where accessibility is non-negotiable. For low-level control over positioning in any framework: Floating UI. For quick tooltips with minimal config: Tippy.js. For production React UIs that must be accessible: Radix Tooltip/Popover.

Key Takeaways

• Floating UI is framework-agnostic — core is vanilla JS, @floating-ui/react adds React hooks
• Floating UI handles all edge cases — viewport overflow, flip, shift, arrow, virtual elements
• Tippy.js is easiest to get started — <Tippy content="Tooltip"> wraps any element
• Radix Tooltip is fully WAI-ARIA compliant — focus management, screen readers, keyboard nav
• Tippy.js is built on Popper.js — Floating UI's predecessor, still maintained but less active
• Radix Popover manages open state — controlled and uncontrolled modes, portal rendering
• Floating UI powers Radix internally — Radix uses @floating-ui/react-dom under the hood

Floating UI: The Positioning Engine

Floating UI provides the geometry and collision detection algorithms — you wire up the DOM refs and React state yourself.

Installation

npm install @floating-ui/react
# For vanilla JS (no React):
npm install @floating-ui/dom

Basic Tooltip

import {
  useFloating,
  autoUpdate,
  offset,
  flip,
  shift,
  useHover,
  useFocus,
  useDismiss,
  useRole,
  useInteractions,
  FloatingPortal,
} from "@floating-ui/react";
import { useState } from "react";

interface TooltipProps {
  content: string;
  children: React.ReactElement;
}

export function Tooltip({ content, children }: TooltipProps) {
  const [isOpen, setIsOpen] = useState(false);

  const { refs, floatingStyles, context } = useFloating({
    open: isOpen,
    onOpenChange: setIsOpen,
    placement: "top",
    // Keep in sync with scroll and resize
    whileElementsMounted: autoUpdate,
    middleware: [
      offset(8),           // Distance from reference
      flip(),              // Flip to bottom if no space above
      shift({ padding: 8 }), // Shift horizontally to stay in viewport
    ],
  });

  // Interaction hooks — compose behaviors
  const hover = useHover(context, { move: false });
  const focus = useFocus(context);
  const dismiss = useDismiss(context);
  const role = useRole(context, { role: "tooltip" });

  const { getReferenceProps, getFloatingProps } = useInteractions([
    hover,
    focus,
    dismiss,
    role,
  ]);

  return (
    <>
      {/* Attach to trigger element */}
      {React.cloneElement(children, {
        ref: refs.setReference,
        ...getReferenceProps(),
      })}

      {/* Tooltip — rendered in portal to escape stacking contexts */}
      <FloatingPortal>
        {isOpen && (
          <div
            ref={refs.setFloating}
            style={{
              ...floatingStyles,
              background: "#1a1a1a",
              color: "#fff",
              padding: "4px 8px",
              borderRadius: 4,
              fontSize: 12,
              zIndex: 9999,
            }}

    middleware: [
      offset(10),
      flip(),
      arrow({ element: arrowRef }),
    ],
  });

  return (
    <>
      <div ref={refs.setReference}>{children}</div>

      <div ref={refs.setFloating} style={floatingStyles}>
        {content}
        {/* FloatingArrow renders an SVG arrow positioned correctly */}

Radix UI Tooltip and Popover: Accessible Components

Radix provides fully accessible, headless components with correct ARIA roles, focus management, and keyboard navigation — you bring your own styles.

Installation

npm install @radix-ui/react-tooltip @radix-ui/react-popover

Tooltip

import * as Tooltip from "@radix-ui/react-tooltip";

// Provider wraps your app — controls delay behavior globally
export function App() {
  return (
    <Tooltip.Provider delayDuration={300} skipDelayDuration={500}>

    </Tooltip.Provider>
  );
}

// Individual tooltip
export function DeleteButton() {

When to Use Each

Choose Floating UI if:

• Building a component library from scratch (unstyled primitives)
• Need maximum control over positioning behavior and styling
• Framework-agnostic — Vue, Svelte, vanilla JS, or React
• Virtual element positioning (context menus, cursors)
• Complex middleware requirements (custom offset logic)
• Want to understand exactly what's happening — no magic

Choose Tippy.js if:

• Quick tooltip needed with minimal setup
• Vanilla JS project or legacy codebase
• Want built-in themes and animations without CSS work
• Simple hover tooltips where accessibility is secondary
• Prototyping or internal tools where ARIA isn't critical

Choose Radix Tooltip/Popover if:

• React/Next.js production application
• Accessibility is required — screen readers, keyboard navigation
• Using shadcn/ui (Radix is the foundation)
• Want compound component API with proper focus management
• Need asChild pattern to avoid extra DOM elements
• Building a design system where consumers control all styling

Ecosystem and Community Health

Floating UI has effectively won the positioning engine category. When Popper.js creator Vlad Moroz deprecated Popper.js in favor of Floating UI, the ecosystem converged rapidly. In 2026, Floating UI underlies Radix UI, Mantine, Headless UI (Tailwind), and Arc browser's web extension overlays. The 29k GitHub stars and 12M weekly npm downloads confirm that Floating UI is infrastructure — it's used by nearly every modern React component library, whether developers know it or not.

The relationship between Floating UI and Radix is particularly important: Radix uses Floating UI's @floating-ui/react-dom package internally for all its overlay positioning. This means that when you use @radix-ui/react-tooltip, you're already depending on Floating UI — you just don't need to interact with it directly. The dual usage pattern is common: use Radix for standard accessible components, reach for Floating UI directly only when you need to build something the Radix primitives don't cover.

Tippy.js's activity has slowed relative to Floating UI and Radix. The library is maintained but not seeing the same pace of development. The npm downloads (3M weekly) are still substantial, largely from legacy projects that haven't migrated. The Popper.js dependency is a concern for bundle size — Floating UI is smaller, faster, and more capable. For new projects in 2026, Tippy.js is rarely the right choice unless the project is vanilla JavaScript or you need a quick prototyping tool.

Radix UI primitives are now controlled by Radix (part of WorkOS), a company with significant revenue and engineering resources. The pace of Radix development accelerated in 2025 with new primitives being added quarterly. The WAI-ARIA compliance commitment is a core product principle — every new component ships with a full ARIA specification review.

Real-World Adoption

Floating UI's 12M weekly downloads come primarily from indirect usage. Every shadcn/ui installation includes Radix UI which includes Floating UI. Every Mantine installation includes Floating UI directly. Component library authors building design systems for enterprise clients use Floating UI as the positioning layer. Direct usage — writing useFloating() yourself — is more common for custom components like inline color pickers, command palettes, and context menus. For the full comparison of React component libraries that build on Floating UI, see best React component libraries 2026.

Radix Tooltip and Popover are the de facto standard for React applications built with shadcn/ui, which has become the dominant React component library. When the State of JavaScript 2025 survey data showed shadcn/ui adoption surpassing Material UI and Chakra UI, the downstream effect was that Radix UI primitives became even more ubiquitous. Enterprise React applications that were previously using custom tooltip implementations or Tippy.js are migrating to Radix Tooltip when they adopt shadcn/ui. For animation of these floating elements, see Framer Motion vs Motion One vs AutoAnimate 2026.

Tippy.js's remaining primary use case in production code is in vanilla JavaScript applications, WordPress plugins, and legacy jQuery applications that need tooltip functionality without a React dependency. For these contexts, Tippy.js remains a reasonable choice with its simple tippy(element, { content: "Tooltip" }) API.

Developer Experience Deep Dive

Building a tooltip with Floating UI requires more boilerplate than Tippy.js but less than you might fear. The useFloating hook handles the geometry — you provide refs for the reference and floating elements, specify placement and middleware, and get back position styles. The interaction hooks (useHover, useFocus, useDismiss) compose together cleanly, and the TypeScript types make the API surface discoverable. A complete, accessible tooltip implementation is around 50-60 lines of code.

The middleware system is Floating UI's most powerful feature. The offset middleware adds distance between the reference and floating elements. The flip middleware switches placement when the floating element would overflow the viewport. The shift middleware slides the floating element along its axis to keep it in view. The arrow middleware calculates the position for a pointing arrow. Combining these gives you correct positioning behavior for any viewport size or scroll position without custom logic.

Radix UI's API follows the compound component pattern where every part of the component (Trigger, Content, Arrow, Close) is a separate exported primitive. This pattern is more verbose than Tippy.js's single-component API, but it gives you complete control over rendering. asChild is the key prop — it lets Radix components forward all their behavior to your own DOM element, avoiding the extra <span> wrapper that otherwise appears in the DOM tree.

Tippy.js's API is the simplest: wrap your trigger element in <Tippy content="...">. This simplicity is the primary advantage — for simple hover tooltips where accessibility is secondary and you need something working immediately, Tippy.js delivers. The ecosystem of themes and animations that Tippy.js ships with makes it possible to have a polished-looking tooltip in under five minutes.

Accessibility Deep Dive

Accessibility is the critical differentiator between these three libraries, and the differences are not subtle. Radix UI implements the full WAI-ARIA 1.2 tooltip role specification: the trigger element gets aria-describedby pointing to the tooltip content's ID, the tooltip content has role="tooltip", keyboard focus (Tab) triggers the tooltip display, and Escape dismisses it. Screen readers announce the tooltip content when the trigger is focused. None of this requires any configuration — it's the default behavior.

Floating UI provides the building blocks for accessibility but requires you to implement it. The useRole hook applies the correct ARIA role to the floating element. The useFocus hook triggers the tooltip on keyboard focus. But you still need to manually manage aria-describedby, id attributes, and screen reader announcements. Done correctly, the result is identical to Radix. Done incorrectly — which is easy when you're focused on visual behavior — the result fails screen reader users silently.

Tippy.js has basic accessibility features: it adds the tooltip trigger role and some ARIA attributes. But the implementation does not fully match WAI-ARIA 1.2, and screen reader behavior varies across assistive technologies. For internal tools where accessibility is less critical, this is acceptable. For public-facing products in regulated industries (healthcare, finance, government), Tippy.js's ARIA implementation is insufficient.

Bundle Size and Performance

In a real application using 20 tooltips, the bundle size difference between the three libraries is negligible. Floating UI at 10KB, Tippy.js at 15KB, and Radix Tooltip at 8KB — the differences disappear into the background of a typical 500KB-1MB JavaScript bundle. The performance question that matters more in practice is runtime: how much does each library slow down tooltip display?

All three libraries use CSS for positioning when possible, falling back to JavaScript layout calculations only when needed for collision detection. The first time a floating element appears, Floating UI and Radix both compute the position in a single synchronous layout read, minimizing reflow. Tippy.js has similar behavior via Popper.js. In practice, you will not observe any perceptible difference in tooltip display speed between the three.

The genuine performance concern is event listener overhead on pages with hundreds of tooltips. Radix uses delegation and lazy initialization — components don't register event listeners until they're first interacted with. Floating UI's autoUpdate function only starts watching for position updates when the floating element is visible. Both patterns keep idle-state overhead near zero.

Final Verdict 2026

For React applications, use Radix Tooltip for simple tooltips and Radix Popover for interactive overlays. If you're using shadcn/ui, these are already wrapped and available as components/ui/tooltip.tsx. The accessibility guarantees, TypeScript support, and compound component flexibility make them the correct defaults.

Use Floating UI directly when you need to build something that Radix doesn't cover: context menus that follow the cursor, inline annotation popovers, virtual element positioning, or any overlay for a non-React framework. Floating UI is the right tool when the positioning primitive is the feature rather than a means to an end.

Avoid Tippy.js for new React projects unless you're prototyping or maintaining a legacy codebase. The Popper.js foundation, weaker ARIA support, and slower maintenance pace make it the least future-proof of the three options in 2026.
