EffectCraft: a free, open-source After Effects alternative

EffectCraft is the motion graphics and compositing app of the Crafting Apps: an open-source, clean-room take on Adobe After Effects. It has the same panels and keyframe behavior, shape layers, masks, text animators, JavaScript expressions, puppet pins, classic 3D, a big effects library and Lottie import and export.

The online version is the official web build from the v0.9.2 release (2026-10-12). It runs locally in your browser; a desktop browser with WebGPU or WebGL2 works best.

What EffectCraft can do

After Effects muscle memory

Project, Composition, Timeline, Effect Controls and Effects & Presets panels, with the same twirl-down shortcuts (P, S, R, T, U, UU…).

Layers and keyframes

Solids, shapes, text, footage, precomps, nulls, cameras and lights; linear, Bezier, hold and roving keyframes; time remapping.

Expressions

JavaScript expressions with the After Effects object model: wiggle, loopOut, valueAtTime and friends.

Effects and simulation

Color, distort, generate (Fractal Noise, Write-on), keying, CC Particle World, Shatter, Caustics, audio effects and more.

Lottie both ways

Export compositions to Lottie JSON or .lottie for the web and apps, and import Lottie files back in.

No FFmpeg

Encoding and decoding are pure Rust, shared with FilmCraft, plus EffectCraft's own VP9, AV1, HEVC and Opus.

Where can I download EffectCraft safely?
