Headless API

Frames, cels & tags

Frame timeline with durations, copy/empty frames, Continuous and linked cels, tags with playback, onion skinning and a live preview.

Multi-document workspace

Document tabs with independent history, selection, view and colors; dockable/reorderable panels; validated keyboard bindings with .pxkeys import/export.

Native & interchange formats

ZIP-based .pvc save/open, PNG import (including Adam7), PNG/frame-sequence/sheet+JSON export, GIF export and an Aseprite supported-subset import/export.

Headless core

Document model, compositor, codecs and workspace utilities run headlessly in Node — the UI consumes the same compositor as atlas/GIF export.

Local-first & offline

All editing stays in your browser. Release packages include a standalone offline-capable HTML file, with fonts and icons bundled locally.
