32 of my After Effects scripts are online for free (MIT), plus a page that bundles just the ones you want into a single toolbar
Most of these exist because I got tired of doing the same thing by hand for the hundredth time and wrote a script instead. They piled up, so I finally stuck them on a site. Everything's free and MIT, so you can open them, change them, use them in paid work, whatever you want.
What makes it less of a mess than the usual "here's a bunch of loose scripts" is something I called Build-a-bar. You tick the ones you actually want, hit download, and you get a zip with one responsive, fast, scriptui dockable panel (icon button per script) plus only those scripts. So your Window menu doesn't turn into a wall of scripts, it's just one panel with your picks. Drop it in ScriptUI folder, restart AE, done.
Each one also has a docs page if you want to see exactly what it does before installing.
Full list:
Animation & rigging
- Limb-a-tron: two-segment IK/FK limb rig. Drag one null to bend it, bake it out when you're happy.
- Linearizer: drive existing keyframed animation off any slider, position, or rotation value.
- PathMaster: stick a layer's position on a shape path and retime/re-ease/loop it.
Composition
- Guiderator: type a number (or a formula like 1920/2) and it drops the guide there.
- Slidotron 16x9 / 9x16: one-click horizontal or vertical slide-reveal rigs with mirrored mattes.
Effects, color & audio
- BurstMate: drops in a rigged radial stroke burst you can dial in (color, length, density, decay).
- ChromaBlenderizer: ramp a color range across selected fills, strokes, and effect colors.
- Sync-o-tron: make any property audio-reactive in a click.
- sfxMaster: run Voice Over / SFX / Music off three master sliders, audio auto-sorted into groups.
Keyframes
- Elast-o-matic: adds elastic overshoot or a gravity bounce after a keyframe.
- KeyBot: batch-edit selected keyframe values with = + - x / per axis.
- KeyCloneMatic: repeat a keyframe set down the timeline, fixed or decaying interval.
- Valuatron: stamp a key at the playhead for every selected property at once.
Layers
- Controllerizer: pull selected properties from a bunch of layers onto one control null via expressions.
- NullBot: parent a group of layers to one null at their average position.
- Opac-o-bot: basically parenting but for Opacity, via expression.
- OrderMaster: reverse or shuffle the stacking order of layers or shape groups.
- Parent-o-bot: blend a layer's Position/Scale/Rotation/Opacity toward up to two parents.
- Rectangulator: turn a parametric rectangle into a real bezier shape with per-corner rounding.
- Reseterator: zero out the transform origin on selected layers (anchor to 0,0,0).
- SubtitleForge: builds a caption rig, text plus a self-sizing box with stroke and shadow.
- TextMate: highlight every case-sensitive match of a word in a text layer.
- TimeWarp-a-tron: drive Time Remap off a 0-100 slider over an in/out range you set.
Paths & shapes
- Centralizer: drops center + bounding-box guides around shapes, images, or precomps, works on multiselect.
- Distributron: spread a comp's layers along a shape path, each rotating to follow the curve.
- Originator: recenter a shape path's origin on (0,0) so it scales and rotates the way you'd expect.
- Trace-o-matic: turn a layer's masks into a shape layer with hold-keyframed paths.
- VertexMaster: convert a bezier path's vertices/tangents into nulls you can key and parent.
Utilities
- Iteratron: spread a property evenly across a stack of layers between a start and end value.
- RandoMatic: replace selected keyframe values with fresh random numbers, per-axis range.
- Triminator: slap a pre-keyframed 0-100% Trim Paths reveal on a shape layer.
Ping me if any issues surface - those were all personal tools, so bugs may exist :)
