The open-source motion graphics and compositing app with After Effects’ layout, running in a browser tab. Animate titles, stack effects, light a 3D scene and render a video. Your footage stays on your computer.
Project, Composition, Timeline, Effect Controls, Effects & Presets and the Render Queue sit where you expect them, and the timeline shortcuts work: P, S, R, T, U, F9. Here is some of what the web build does.
Linear, Bezier, hold, auto and continuous Bezier keys, Easy Ease on F9, roving keys and a Graph Editor with value and speed graphs. Time remapping, time stretch, freeze frames and markers work at any frame rate, 29.97 drop-frame included.

Blur and sharpen, color correction (Curves, Levels, Lumetri Color), distort, keying, generate (Fractal Noise, Gradient Ramp, Audio Spectrum), simulation (CC Particle World, Shatter, Card Dance), time effects and more, each with its familiar parameters and defaults.

3D layers with material options, one- and two-node cameras with depth of field, parallel, spot, point and ambient lights with soft shadows, and layers that intersect correctly. Orbit, pan and dolly the camera, or switch to Front, Top and Custom views.

H.264 MP4, ProRes MOV (including 4444 with alpha), HEVC, AV1, WebM with VP9 alpha, image sequences, animated GIF and WAV. The encoders are written in Rust, so the browser build renders the same formats as the desktop app. Finished renders arrive as downloads.

Screenshot from the EffectCraft project.Open the AI panel next to the timeline, paste an OpenAI, Google Gemini or OpenRouter key, and generate a background plate, a cut-out element or a texture. One click adds it to your composition as a layer, ready for keyframes and effects. You can also send the current frame to the model and bring the edited still back.
Requests go from your browser to the provider. We never see your key, prompts or frames, and we add no markup.
How the AI tools workThe editor is the official build, byte for byte. Around it we add a few things the bare build doesn’t have.
Each new EffectCraft release is checked against its published SHA-256 checksum and deployed here. You are on v0.8.0.
The app file is too large for ordinary static hosting, so we serve it from Cloudflare storage, compressed on the way. After the first visit the app’s service worker opens it from cache.
Generate plates and elements or edit a rendered frame with OpenAI, Gemini or OpenRouter models, straight from the browser.
No account, no watermark, no upload. Your projects live in your own browser’s storage, not on a server.
EffectCraft is in alpha. Expect rough edges, and save often: File › Save keeps the project in your browser and downloads a copy.
Yes. EffectCraft is free and open source, there is no account and no watermark. The optional AI tools use your own API key, so any AI usage is billed by your provider, not by us.
It is the official EffectCraft web build, unmodified, as the ArtCraft team publishes it on GitHub. This site is independent: we host that build, keep it on the latest release and add an AI panel around it.
No. EffectCraft runs inside your browser with WebAssembly. Footage you import is kept in your browser’s own storage, renders happen on your device and finished files arrive as downloads. The only exception is the AI panel, which sends the prompt and frame you choose straight to the AI provider whose key you entered.
The browser version keeps your session in the browser’s storage, so the project you had open comes back on your next visit, unsaved changes included. File › Save also stores the project there (File › Open Recent lists it) and downloads a copy as an .ecproj file. Clearing site data removes it, and some private windows keep nothing, so download projects you care about.
No. EffectCraft saves its own .ecproj format, readable JSON, and cannot open .aep or .aepx files. After Effects plug-ins do not run either. You rebuild the comp in EffectCraft with the same layers, keyframes and effect names.
Any current browser with WebGPU or WebGL2. Chrome and Edge get the most out of it, because they also offer WebGPU inside Web Workers, where EffectCraft renders effects. Other browsers render effects on the CPU, which is slower. Use a desktop or laptop: the app needs a big screen and plenty of memory.
In the browser, the fonts bundled with EffectCraft: Inter, Noto Serif and JetBrains Mono. A web page cannot read the fonts installed on your computer. The desktop app shapes text in any installed font.
Its developers estimate that about 91% of After Effects’ features exist, but EffectCraft is young (its first commit was on October 1, 2026) and in alpha. They say plainly that it is not yet a replacement for After Effects on client work, and behavior still differs in places.
