In-house tool

Layout Animation Explorer

Scrub between captured layout frames, interpolate component positions, and audit motion at any duration.

Layout Animation Explorer is a Web Design Awards in-house tool for motion studies. Drop in a sequence of layout capture frames — positions, sizes, and labels for each component — and the tool interpolates between them, plays the result at any duration, and lets you scrub frame-by-frame to audit timing.

— 02 / What it is

The shape of the tool.

Layout animation is one of those areas where reading the spec, looking at the Framer Motion docs, and running the production build still leaves you guessing what's actually happening between frames. Web design awards are full of nominees with beautiful motion at full speed — and rough motion at 0.1× speed, where the easing breaks, components teleport, or labels rebind incorrectly.

This tool exists to make that rough motion visible. The inputs are an ordered list of frames; each frame is a list of items with id, label, color, x, y, width, and height. Items that exist in both frame N and frame N+1 are interpolated. Items that exist in only one frame fade in or out (visually represented by the explorer's renderer). The output is a canvas you can play, pause, scrub, and re-time.

The point is debugging, not authoring. Use Framer Motion, GSAP, or the View Transitions API to build the animation in production. Use this tool when you need to see what the layout transition would look like in isolation — to share with a colleague, to embed in a case study, or to debug why a specific component is jumping. Combined with the data export from the production page, it's the fastest way to round-trip a motion bug.

— 04 / Key features

What it actually does.

  • Interpolation between any two layout frames using shared item IDs
  • Variable animation duration (150ms to 2000ms) so you can audit at any speed
  • Playhead scrubbing for precise frame-by-frame inspection
  • Play / pause / step controls
  • Automatic handling of items that appear or disappear between frames
  • Item color and label preserved across frames
  • Canvas-based rendering for high-density device support
— 05 / Use cases

When designers reach for it.

  1. 01
    Debugging awards-submission motion

    Nominees often submit case-study pages with layout transitions. When the motion feels 'off' but you can't articulate why, scrubbing in this tool surfaces the timing bug — usually a component without a stable ID, an easing curve that doesn't match the rest of the system, or a frame jump that's hidden at full speed.

  2. 02
    Motion studies before implementation

    Before writing Framer Motion or View Transitions API code, sketch the start and end frames as data, run them through the explorer, and validate the easing feel. Saves implementation churn.

  3. 03
    Case-study assets

    Export scrubbed frames as images to embed in a case study or process post. Showing the in-between frames is often more compelling than showing the start and end states.

  4. 04
    Team alignment on motion direction

    Send a co-worker a frame data set and the URL. They scrub the same animation you scrubbed and can comment on the same moments. Faster than recording a screen capture and circling timestamps.

— 06 / Workflow

A working sequence.

  1. 01
    Capture or author your layout frames

    Each frame is an array of items. Each item needs an id (stable across frames), x, y, width, and height. Optional label and color render visually.

  2. 02
    Drop the frames into the explorer

    The tool ships with a default sample set. To use your own, update the `frames` import in the data file or pass them via props in a custom mount.

  3. 03
    Set the animation duration

    Default is 800ms. Slow it to 200ms to see the snap; slow it to 2000ms to audit easing.

  4. 04
    Play, then scrub

    Run the animation once at full speed to get a feel. Then scrub the playhead to find the moments that feel wrong.

  5. 05
    Identify the bug class

    Most layout animation bugs fall into three classes: unstable IDs (component re-creates instead of moves), wrong easing (cubic-bezier doesn't match the rest of the system), or layout jump (a frame between two captured frames is missing).

  6. 06
    Apply the fix in production

    Round-trip the fix into the production codebase (Framer Motion, View Transitions API, or hand-rolled CSS transitions) and re-capture the frames to confirm.

— 08 / Strengths & trade-offs

The balance.

Strengths
  • Isolates motion debugging from a heavy production build
  • Scrubbable timeline catches timing bugs hidden at full speed
  • Free, runs entirely client-side, no upload
  • Canvas rendering scales to dense compositions
Trade-offs
  • Requires you to author or capture frame data yourself
  • Does not author production motion — debug only
  • No easing-curve editor yet (uses linear interpolation between frames)
  • Items are rectangles; complex shapes need to be approximated
Web Design Awards — Verdict
A purpose-built debugger for layout animations. If you ship motion as a serious part of your design work, scrubbing in this tool will catch bugs that real-time playback hides.

FAQ

  • Do I need an account to use Layout Animation Explorer?

    No. The tool runs entirely client-side, requires no sign-in, and stores nothing on our servers. Frame data is loaded from the page bundle.

  • Can I bring my own frame data?

    Yes. The component accepts a `frames` prop. If you're embedding the tool elsewhere, pass an array of frames where each frame contains items with stable IDs. The default frames in /tools/layout-animation-explorer are a demo set.

  • How does this differ from Framer Motion's tools?

    Framer Motion is an authoring library — it makes layout animations possible in React. This tool is a debugger — it makes layout animations inspectable. They're complementary; use both.

  • Does it work with the View Transitions API?

    It works with frame data, regardless of where that frame data came from. If you've captured layout snapshots from a View Transitions API implementation, you can scrub them here.

  • Why does my animation look correct at full speed but wrong when scrubbed?

    Almost always one of: unstable IDs (so the tool treats it as remove + add, not move), missing intermediate frames (the animation between captured frames is being linearly interpolated), or a real production bug that's hidden by the speed of full playback. Scrubbing surfaces the third class of bugs, which is usually the actionable one.
