Sprite Alive
Most sprite previewers tell you whether an animation is smooth — not whether it'll feel like a game. Sprite Alive closes that gap: a single self-contained HTML file for previewing attacks, idles, walks, and hits with synced placeholder effects — no engine import, nothing uploaded.
Summary
A single self-contained HTML tool for previewing sprite animations the way they'll actually read in a game: drag-and-drop import, automatic frame slicing, playback controls with onion skinning, purpose presets (Attack, Idle, Walk, Hit), and a small plugin system of placeholder effects with live parameters.
What I built
Vanilla JavaScript and Canvas — zero frameworks, no build step. Effects are defined as small self-contained objects, so a new effect drops in with a single addition. The whole thing is one file you can open locally.
What makes it interesting
It leads with a real user need: seeing an attack with a synced beam or impact flash without a full engine import. The single-file design is both a portability choice and a privacy one — because nothing is uploaded, artists protective of unreleased work can use it freely.
