Aseprite AI Artist

Your coding agent, painting in the Aseprite window you already have open.

Not a generated PNG. Not a file changed behind your back. The document on your screen, one pixel at a time — and every step is one Ctrl+Z.

☔ 500×400 · 384 frames at 24 fps · 16 s · 24 layers — drawn by Claude Opus 5.5 through this server.

✨ What it feels like

"Draw me a 32×32 knight in the PICO-8 palette, then give him a 4-frame idle."

You type that, and watch it happen in Aseprite: a palette, a silhouette, shading, layers, a breathing idle, a tagged cycle. The agent looks at its own work after every step, and at the end tells you what it compromised on.

You stay in charge. Don't like the helmet? Ctrl+Z, or just say so.

Works with Claude Code, omp, OpenCode, Codex CLI, Gemini CLI, Cursor, VS Code and Windsurf. Best results so far: Claude Opus 5.5.

🚀 Install

You need Aseprite 1.3+ and Node 22.6+ (macOS, Linux or Windows).

1. The Aseprite extension — then quit and reopen Aseprite:

npx @pebbly/aseprite-ai-artist install-extension

2. Your agent:

Claude Code

/plugin marketplace add with-pebbly/aseprite-ai-artist
/plugin install aseprite@aseprite-ai-artist

omp

omp plugin marketplace add with-pebbly/aseprite-ai-artist
omp plugin install aseprite@aseprite-ai-artist

OpenCode 2.x

npx @pebbly/aseprite-ai-artist install opencode
opencode plugin add github:with-pebbly/aseprite-ai-artist#main::path:opencode

Codex, Gemini, Cursor, VS Code, Windsurf

npx @pebbly/aseprite-ai-artist install codex      # or gemini, cursor, --all

Your config is backed up first; --dry-run shows the change.

3. Check it — restart your agent, then:

npx @pebbly/aseprite-ai-artist doctor

All ticks means you're ready. Updating? Run step 1 again. Odd setups (Steam, custom folders, Windows paths) are in docs/INSTALL.md.

No window? Headless mode

For CI or a batch of assets, the server can run Aseprite itself with no window:

npx @pebbly/aseprite-ai-artist serve --headless --aseprite /path/to/aseprite

Nothing is on disk until the agent saves, and it never touches a file your editor has open. It is never a fallback: if your window isn't attached, the agent asks instead of quietly switching.

🎨 How it draws

Ask /aseprite:studio for anything and it runs the whole job:
