Versions:
Geppetto, currently at version 1.3.1 and offered in three cumulative releases by independent developer Matthijs Groen, is a free, open-source animation utility whose single purpose is to let web authors create lightweight WebGL-based animations and drop them straight into any modern web page. Designed for designers, front-end developers and content managers who need motion graphics without resorting to heavy video files or proprietary plug-ins, the program provides a streamlined timeline editor, key-frame controls and a real-time WebGL preview that runs in the same rendering context the final visitor will see. Typical use cases include hero banners that react to mouse movement, interactive product tours, data-story infographics, and short looping backgrounds for landing pages, all exported as a self-contained folder of minified JavaScript, shader code and optional JSON asset manifests that can be uploaded to any CDN. Because the output is pure standards-compliant WebGL, animations remain vector-crisp, resolution-independent and playable in every evergreen desktop or mobile browser without extra extensions. The tool also exposes a small JavaScript API so that site scripts can control playback speed, seek to markers or bind animations to scroll events, making it suitable for more advanced creative coding projects. Occupying the “Authoring & Animation” sub-category of web-development software, Geppetto keeps its interface minimal: import SVG or lightweight 3-D OBJ files, arrange layers, set easing curves, add interactivity triggers, then publish. All three published versions remain available, with 1.3.1 adding improved shader compilation and broader export targets. Geppetto is available for free on get.nero.com, where downloads are served through trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
