# Data sources and libraries Whip apps can use

> The full list of live data sources (weather, Wikipedia, currency, trivia…) and building blocks (Three.js, PixiJS, physics, audio, charts) in Whip apps.

Apps made on Whip draw from two curated toolkits: about **40 approved live data sources** they can fetch from (weather, Wikipedia, currency rates, trivia, art collections, and more), and a set of **professional building blocks** for graphics, games, sound, charts, and animation — including Three.js, PixiJS, and Matter.js. Here's the full menu.

You never need to memorize any of this. Describe what you want — "a morning briefing with real weather" — and Whip picks the right pieces. But if you know exactly what you're after, you can ask by name: "build it with Three.js" works.

## Live data sources

Apps reach these through Whip's own servers — never the open internet — so every source is [safe, free, and keyless](/using/data-ai-and-consent). Where a source asks for credit, Whip's AI builds the attribution into your app automatically.

<Note>
  This is the complete list — if a source isn't on it, apps can't reach it,
  which is [the safety rail](/using/data-ai-and-consent), not a bug. Separately,
  Whip's AI can research the whole web **while building** your app and bake in
  a snapshot of what it finds — that's how a "2026 movie quiz" gets real 2026
  movies. The list grows over time; [the changelog](/changelog) announces new
  sources.

## Building blocks

These are the professional libraries Whip's AI can build your app with — the same tools human developers use. Grouped by what they unlock:

<AccordionGroup>
  <Accordion title="3D worlds" icon="box">
    **Three.js** (with React Three Fiber and Drei) — spinning planets, 3D
    dice, product viewers, little explorable worlds.
  </Accordion>

  <Accordion title="2D games & physics" icon="joystick">
    **PixiJS** for fast 2D graphics and **Matter.js** for real physics —
    bouncing, stacking, colliding, toppling. Arcade games live here.
  </Accordion>

  <Accordion title="Motion & flair" icon="sparkles">
    **Framer Motion** and **Anime.js** for silky animation,
    **canvas-confetti** and **tsParticles** for celebrations and particle
    effects, plus animated counters and typewriter text.
  </Accordion>

  <Accordion title="Sound" icon="volume-2">
    **Howler** — sound effects and music that work the same on every phone.
  </Accordion>

  <Accordion title="Charts & data" icon="chart-line">
    **Recharts** — line, bar, pie, and area charts for trackers, budgets, and
    dashboards.
  </Accordion>

  <Accordion title="Touch & interaction" icon="hand">
    **use-gesture** for swipes, pinches, and drags; **SortableJS** for
    drag-to-reorder lists; **Embla** for smooth carousels.
  </Accordion>

  <Accordion title="Creative tools" icon="palette">
    **perfect-freehand** for natural drawing and signatures, color pickers
    and palette tools (**react-colorful**, **colord**), and **html-to-image**
    for turning a view into a shareable picture.
  </Accordion>

  <Accordion title="Text, math & practical bits" icon="type">
    Markdown rendering, code syntax highlighting (**Prism**), beautiful math
    equations (**KaTeX**), QR codes, date handling (**date-fns**), toast
    notifications, and thousands of icons (**Lucide**).
  </Accordion>
</AccordionGroup>

Under it all, every app is built with **React** and styled with **Tailwind CSS** — the same foundations behind much of the modern web. That's what makes [what you build real](/building/how-whip-builds-your-app), not a mockup.

## Common questions

<AccordionGroup>
  <Accordion title="Do I need to know these tools to use Whip?" icon="circle-help">
    Not at all. Describe the result you want and Whip chooses the right
    building blocks. Naming a library is a power move for people who already
    have one in mind — never a requirement. Start with
    [prompt tips](/building/prompt-tips-and-ideas) instead.
  </Accordion>

  <Accordion title="Can an app use a data source that isn't listed?" icon="globe-lock">
    No — the list is a hard boundary, enforced by Whip's servers. It keeps a
    stranger's app from sending your data somewhere sketchy. If you want live
    data from something not listed, ask in the
    [Discord](https://discord.com/invite/bsSeNMQkTZ) — new sources get added
    over time.
  </Accordion>

  <Accordion title="Why did my app show a credit line I didn't add?" icon="badge-check">
    Some sources (Wikipedia, museum collections, trivia databases) require
    attribution. Whip's AI adds those credits automatically so your app plays
    by the rules.
